So David, naħseb fil lecture
huwa ma xi għalf jibred.

353
00:11:52,700 --> 00:11:53,875
Mela ejja jikteb programm.

354
00:11:53,875 --> 00:11:56,000

355
00:11:56,000 --> 00:11:58,540
Sabiex inti tista 'tagħmel li
numru ta 'modi differenti.

356
00:11:58,540 --> 00:12:00,040
Tista 'tuża kwalunkwe tip ta' editur test.

357
00:12:00,040 --> 00:12:03,090
Inti tista 'tuża Nano, inti
jistgħu jużaw Vim, Emacs.

358
00:12:03,090 --> 00:12:05,110
Dawk huma ftit aktar kumplikata.

359
00:12:05,110 --> 00:12:06,822

360
00:12:06,822 --> 00:12:09,030
Jew tista 'tuża xi ħaġa fil-
hawnhekk li sejjaħ gedit.

00:12:19,480 --> 00:12:21,870

366
00:12:21,870 --> 00:12:27,870
Allura gedit hija bażikament

00:16:58,300 --> 00:16:59,070
Ejja jagħmlu dan.

506
00:16:59,070 --> 00:17:00,310
Kun ċert li jaħdem.

00:17:00,960 --> 00:17:02,430

509
00:17:02,430 --> 00:17:03,610
Xogħlijiet, run.

510
00:17:03,610 --> 00:17:08,484
Hekk ./hi biża.

511
00:17:08,484 --> 00:17:09,609
Dan huwa l-ewwel programm tiegħek.

512
00:17:09,609 --> 00:17:10,800
Let me jagħmilha akbar.

513
00:17:10,800 --> 00:17:15,130

514

Allura verament good-- Yeah, x'hemm up?

515
00:17:16,833 --> 00:17:18,833
STUDENT: Għaliex ma jkun
li meta I jieħdu gedit,

516
00:17:18,833 --> 00:17:21,809
ma tagħti me ieħor
linja għal hi.txt gedit?

517
00:17:21,809 --> 00:17:23,793

518
00:17:23,793 --> 00:17:25,690
Hija biss jpoġġi l-cursor għal linja.

519
00:17:25,690 --> 00:17:26,273
STUDENT: Yeah.

520
00:17:26,273 --> 00:17:27,265

hemm fil-quċċata ħafna?

525
00:17:37,070 --> 00:17:39,800
STUDENT: Has-ebda Harvard J
appliance, u l-cursor

526
00:17:39,800 --> 00:17:41,237
huwa biss it-triq kollha lejn ix-xellug.

527
00:17:41,237 --> 00:17:42,986
JASON Hirschhorn: All
il-mod lejn ix-xellug?

528
00:17:42,986 --> 00:17:43,569
STUDENT: Yeah.

529
00:17:43,569 --> 00:17:44,810
Ma ħaddieħor jkollhom dak?

530
00:17:44,810 --> 00:17:46,920
>> JASON Hirschhorn: Oh, ukoll J
Harvard huwa biss bħall-username.

531
00:17:46,920 --> 00:17:48,770
Allura dan huwa biss l-username standard.

532
00:17:48,770 --> 00:17:49,978
>> STUDENT: Hija waqfiet jirrispondu.

533

JASON Hirschhorn: Oh,
huwa obbligat jieqfu jirrispondu.

535
00:17:52,840 --> 00:17:55,570
OK, sabiex dak li għandek tagħmel hu
inti għandek li tagħlaq out ta gedit.

536
00:17:55,570 --> 00:17:58,360
Tant qrib minn gedit,
u għandu jirritorna.

537
00:17:58,360 --> 00:18:00,726
Allura huwa gedit miftuħa fuq tiegħek
appliance dritt issa?

538
00:18:00,726 --> 00:18:02,636

539
00:18:02,636 --> 00:18:05,510
Jekk inti ħruġ minnha, għandu
ritorn u inti għandek tkun tajba biex tmur.

540
00:18:05,510 --> 00:18:08,257

541
00:18:08,257 --> 00:18:08,840
Did dak ix-xogħol?

542
00:18:08,840 --> 00:18:10,824

543
00:18:10,824 --> 00:18:13,850
>> STUDENT: Allura ma inti tuża
il-kmand gedit li open--

544
00:18:13,850 --> 00:18:16,350
JASON Hirschhorn: Le, l-ewwel
kmand gedit kien żball.

545
00:18:16,350 --> 00:18:17,930

546
00:18:17,930 --> 00:18:19,860
L-ewwel gedit kmand,
I tagħmel hi.txt gedit.

547
00:18:19,860 --> 00:18:21,170

548
00:18:21,170 --> 00:18:24,240
So I tagħtiha isem, hi.txt hekk gedit.

549
00:18:24,240 --> 00:18:27,070
hi.txt huwa l-isem tal-fajl.

550
00:18:27,070 --> 00:18:28,890
L-ewwel waħda kienet biss
żball, u mbagħad

551
00:18:28,890 --> 00:18:30,450
I malajr magħluqa mill-programm.

552
00:18:30,450 --> 00:18:36,737
Għalhekk il-kwistjoni kienet
jekk I do gedit, jien ma

553
00:18:36,737 --> 00:18:39,320
ser tkun tista 'verament tagħmel
kull ħaġ'oħra fil-linja kmand tiegħi

554
00:18:39,320 --> 00:18:42,390
sal I tagħlaq dik gedit, so I
jaħsbu li huwa dak li dam fis.

555
00:18:42,390 --> 00:18:43,689
Hekk tagħlaq il-gedit.

556
00:18:43,689 --> 00:18:45,730
Hija ser jirritorna barra minn dak
programm, u mbagħad tkun taf

00:18:45,730 --> 00:18:49,090
tkun tista 'fil-fatt tip
fil-linja tal-kmand-ġdid.

00:18:52,698 --> 00:18:57,715

562
00:18:57,715 --> 00:19:00,410
Hekk biss tagħmel ċert li tagħlaq
jekk inti jidħlu f'inkwiet.

563
00:19:00,410 --> 00:19:01,860

564
00:19:01,860 --> 00:19:04,465

Imma ejja ngħidu Irrid li jibdlu.

568

Irrid ngħid klassi hi.

570
00:19:13,250 --> 00:19:15,670
Imma nixtieq li żżomm din it-template.

571
00:19:15,670 --> 00:19:17,980
I ma jkollhomx biex jikteb
il-programm kollu mill-ġdid.

572
00:19:17,980 --> 00:19:19,700
I tixtieq li żżomm l-template.

573
00:19:19,700 --> 00:19:20,480
Kif nista kopja?

574
00:19:20,480 --> 00:19:25,580

575
00:19:25,580 --> 00:19:26,210
>> Faċli.

576
00:19:26,210 --> 00:19:29,680
Allura newhi.c hi.c cp.

577
00:19:29,680 --> 00:19:32,767

578
00:19:32,767 --> 00:19:34,340
Issa għandi tnejn.

579
00:19:34,340 --> 00:19:48,330
U mbagħad I tista 'tiftaħ newhi.c,
u minflok sempliċiment tgħid hi,

580
00:19:48,330 --> 00:19:51,280
I ser jgħidu klassi hi!

581
00:19:51,280 --> 00:20:00,530

582
00:20:00,530 --> 00:20:01,780

00:20:11,530 --> 00:20:13,600

592
00:20:13,600 --> 00:20:17,610
Mela jekk inti tixtieq li kopja xi ħaġa,
faċli bħal dik. cp hija kopja.

593
00:20:17,610 --> 00:20:22,060

Mela jekk inti kienu se
tiftaħ it up fil gedit jew Nano,

637
00:21:44,670 --> 00:21:46,240
dan huwa dak li qed ittajpjar fl.

638
00:21:46,240 --> 00:21:48,710
Meta inti josservawha, imbagħad
ikollok eżekutibbli fajl.

C'est hi.

640

Mela jekk inti fetaħ hi, li għaddej
li jkun mazz ta 'gibberish lilek.

641

Huwa bażikament se tkun
mazz ta 'struzzjonijiet kompjuter.

Jaqbeż il-gun.

649
00:22:09,010 --> 00:22:11,880
Allura neħħi hi iva.

650
00:22:11,880 --> 00:22:12,930
Mela allura ejja do ls.

651
00:22:12,930 --> 00:22:13,930
I ma jkollhomx hi aktar.

652
00:22:13,930 --> 00:22:16,770
Allura meta inti tagħmel, li meta inti
jieħdu l-programm li inti kiteb

653
00:22:16,770 --> 00:22:18,100
u inti tagħmel fajl eżekutibbli.

654
00:22:18,100 --> 00:22:20,720
Sabiex tagħmel hi.c-- tajjeb, jagħmlu hi.

655
00:22:20,720 --> 00:22:21,956

656
00:22:21,956 --> 00:22:24,060

Inti biss jiktbu tagħmel.

661
00:22:31,210 --> 00:22:32,680
Allura dan jagħmel il-fajls eżekutibbli.

662
00:22:32,680 --> 00:22:36,200
Allura meta inti tagħmel ls, issa għandek hi.

663
00:22:36,200 --> 00:22:38,320
Allura dan huwa dak li int
ser tmexxi effettivament.

664
00:22:38,320 --> 00:22:45,130
U għalhekk inti tmexxi li billi tagħmel
./hi, u din tmur program tiegħek.

665
00:22:45,130 --> 00:22:51,066
Imma jekk jien tipprova tagħmel dan ma '
hi.c, ebda, mhuwiex sejjer jaħdem.

666
00:22:51,066 --> 00:22:52,190

kull min huwa interessat,

673
00:23:02,226 --> 00:23:04,350
meta inti jaqbżu barra ta '
direttorju, huwa l-dot dot.

675
00:23:05,580 --> 00:23:08,960
Ma xi ħadd ikollu idea ta 'dak
forsi biss il-dot mezzi singular?

676
00:23:08,960 --> 00:23:15,085

677
00:23:15,085 --> 00:23:15,960
STUDENT: [inaudible].

678
00:23:15,960 --> 00:23:16,631

679
00:23:16,631 --> 00:23:18,880
JASON Hirschhorn: Huwa
attwalment il-direttorju kurrenti.

680
00:23:18,880 --> 00:23:20,730
Allura huwa direttorju kurrenti tiegħek.

681
00:23:20,730 --> 00:23:21,920

682
00:23:21,920 --> 00:23:22,610
Hekk jien hawn.

683
00:23:22,610 --> 00:23:23,700
Jien fil-biża.

684
00:23:23,700 --> 00:23:27,090
Jekk I do cd dot, ma tagħmel xejn.

685
00:23:27,090 --> 00:23:28,750
Huwa jieħu me direttorju kurrenti tiegħi.

686
00:23:28,750 --> 00:23:34,407
Allura żejda ftit, iżda inti għandek
biex tagħmel dan, hekk ./ isem tal-programm tiegħek,

687
00:23:34,407 --> 00:23:36,490
sabiex tmexxi tiegħek
programm, għandek tagħmel dan.

688
00:23:36,490 --> 00:23:38,020

689
00:23:38,020 --> 00:23:38,520
OK.

690
00:23:38,520 --> 00:23:39,555

691
00:23:39,555 --> 00:23:42,032
>> STUDENT: Jekk inti tagħmel cd dot
dot dot, madankollu ħafna tikek

692
00:23:42,032 --> 00:23:43,990
se biss tieħu inti up
li ħafna direttorji?

693
00:23:43,990 --> 00:23:46,527
>> JASON Hirschhorn: You tfisser
bħal cd dot dot dot dot?

694
00:23:46,527 --> 00:23:47,110
STUDENT: Yeah.

695
00:23:47,110 --> 00:23:47,985
JASON Hirschhorn: No

696
00:23:47,985 --> 00:23:48,850

697
00:23:48,850 --> 00:23:52,130
So attwalment Ftakar I ma Ls-l?

698
00:23:52,130 --> 00:23:53,290

699
00:23:53,290 --> 00:23:56,800
Jekk nagħmel xi ħaġa oħra, I jistgħu ls -a.

700
00:23:56,800 --> 00:23:59,940
Allura dak li dan jgħid hu -a
jurik kollox.

701
00:23:59,940 --> 00:24:03,180
Allura Dan juri li inti affarijiet li huma
moħbija u affarijiet li mhumiex moħbija.

702
00:24:03,180 --> 00:24:10,880
Mela jekk tinnota li meta għamilt
biss ls, I biss raw li Jittieħed,

703
00:24:10,880 --> 00:24:12,060
l-għalf I magħmula.

704
00:24:12,060 --> 00:24:14,640
Jekk I do -a, li għaddej
biex juru lili kollox.

705
00:24:14,640 --> 00:24:18,460
U direttorju hekk attwali,
direttorju hawn fuq.

706
00:24:18,460 --> 00:24:22,025

707
00:24:22,025 --> 00:24:22,900
Ma li jagħmel sens?

708
00:24:22,900 --> 00:24:23,130
Yeah?

709
00:24:23,130 --> 00:24:25,296
>> STUDENT: Iżda dawn mhumiex
attwalment fid-direttorju.

710
00:24:25,296 --> 00:24:30,938
Id-direttorju attwali mhix fiha nnifisha,
hekk għaliex juru dawk tikek ġewwa?

711
00:24:30,938 --> 00:24:33,910
>> JASON Hirschhorn: Inti jfissirx li huwa
simili huwa mhux fil-direttorju.

712
00:24:33,910 --> 00:24:34,810
>> STUDENT: Dritt.

713
00:24:34,810 --> 00:24:36,620
Allura aħna għandna lista ta 'affarijiet
li huma fid-direttorju.

714
00:24:36,620 --> 00:24:37,630
>> JASON Hirschhorn: Naħseb
huwa fl-direttorju.

715
00:24:37,630 --> 00:24:41,190
Bħal -a turi kollox, anki jekk
huwa moħbija ġewwa l-direttorju.

716
00:24:41,190 --> 00:24:44,440
Hekk naħseb huwa biss rotta għall-
direttorju kurrenti jekk dan jagħmel sens.

717
00:24:44,440 --> 00:24:46,400

718
00:24:46,400 --> 00:24:47,400
Huwa rikursivi ftit.

719
00:24:47,400 --> 00:24:48,300
Huwa simili Bidu.

720
00:24:48,300 --> 00:24:48,920
X'hemm up?

721
00:24:48,920 --> 00:24:52,090
>> STUDENT: Allura inti qal
turi -A [inaudible]?

722
00:24:52,090 --> 00:24:53,215
JASON Hirschhorn: -a, yeah.

723
00:24:53,215 --> 00:24:54,964

724
00:24:54,964 --> 00:24:56,572
>> STUDENT: Dak li jagħmilha [inaudible]?

725
00:24:56,572 --> 00:24:59,280
JASON Hirschhorn: Well, per eżempju,
ejja jmorru lura sal-quċċata.

726
00:24:59,280 --> 00:25:00,890

727
00:25:00,890 --> 00:25:04,180
Huwa normalment Jittieħed inti m'għandekx mess
ma 'u inti m'għandekx bżonn ninkwetaw dwar.

728
00:25:04,180 --> 00:25:07,180
Allura dan huwa tip ta 'l-dar.

729
00:25:07,180 --> 00:25:10,230
Jekk I do -a, I tikseb tunnellata ta 'għalf.

730
00:25:10,230 --> 00:25:14,760

731
00:25:14,760 --> 00:25:15,440
Dak kollu li Jittieħed.

732
00:25:15,440 --> 00:25:18,840

733
00:25:18,840 --> 00:25:21,258
U inti ma għandekx bżonn li mess
ma xi li Jittieħed.

734
00:25:21,258 --> 00:25:23,716
Definitely ma tibda tmur
fil hawn u biss neħħi Jittieħed.

735
00:25:23,716 --> 00:25:27,190
>> [Rires]

736
00:25:27,190 --> 00:25:32,440
>> Yeah, dan kien ftit aktar
Jittieħed comfy, iżda dan huwa tajjeb li tkun taf.

737
00:25:32,440 --> 00:25:34,310
Naħseb li huwa tajjeb li tkun taf.

738
00:25:34,310 --> 00:25:35,540

739
00:25:35,540 --> 00:25:41,420
Imma jekk inti qatt tixtieq li tip -a
fil-intier ta 'dan il-kors,

740
00:25:41,420 --> 00:25:42,540
biss tinsa dan.

741
00:25:42,540 --> 00:25:43,040
X'hemm up?

742
00:25:43,040 --> 00:25:44,436
>> STUDENT: X'inhu l-Ls-l?

743
00:25:44,436 --> 00:25:46,310
JASON Hirschhorn: Li
turi li inti l-permessi.

744
00:25:46,310 --> 00:25:50,269
Bażikament inti tuża dik
għall-permessi, hekk -l.

745
00:25:50,269 --> 00:25:52,060
Dan juri li inti ftit
daqsxejn aktar informazzjoni,

Għalhekk dawn huma direttorji.

751
00:26:05,500 --> 00:26:08,250
U mbagħad jaqra, jikteb, tesegwixxi.

Għalhekk dawn huma permessi għal
Naħseb utent, grupp, dinja.

Totalment esaġerata.

755
00:26:15,610 --> 00:26:18,580
Inti qed tmur biex jmorru f'din bħal

00:26:45,165 --> 00:26:47,960

776
00:26:47,960 --> 00:26:52,667
Jiddispjacini, messing mad-daqs huwa

Ejja ngħidu jien ridt li jiċċaqalqu
kollox għall-direttorju ġdida

792
00:27:20,090 --> 00:27:21,600
minħabba I biss trid
li jorganizzaw dan, id-dritt?

793
00:27:21,600 --> 00:27:22,560
Allura kif nagħmel dan.

794
00:27:22,560 --> 00:27:23,650

Aħna qed tmur biex jużaw move darb'oħra.

Allura jimxu hi.c.

798
00:27:26,320 --> 00:27:27,620

799
00:27:27,620 --> 00:27:29,810
U dak li inti tista 'tagħmel huwa
tibda elenkar Jittieħed,

800
00:27:29,810 --> 00:27:32,268
u l-aħħar ħaġa inti lista hija
fejn huwa għaddej biex jġorrhom.

801
00:27:32,268 --> 00:27:38,230
Allura jimxu hi.c, hi newhi newhi.c, hi_dir.

802
00:27:38,230 --> 00:27:41,960

803
00:27:41,960 --> 00:27:45,880
U għalhekk mċaqalqa kollox fis
l-aħħar ħaġa int semma.

00:27:45,880 --> 00:27:49,462
Allura mbagħad bidla direttorju, ls hi_dir.

għaliex inti ma għandekx ħin
għal twissijiet, neħħi-f.

Allura issa Sharon u
Hannah se jmorru fuq xi wħud

1040
00:35:44,400 --> 00:35:46,720
tal-loġika wara problema sett wieħed.

1041

1046
00:35:59,170 --> 00:36:00,154
Dan huwa Sharon.

1047
00:36:00,154 --> 00:36:03,106
Aħna kemm CS50 TFS, u
aħna qed tmur biex jagħtuk

1048
00:36:03,106 --> 00:36:06,050
intro ftit fuq koppja importanti
affarijiet għall-problema sett wieħed.

1049
00:36:06,050 --> 00:36:09,670
Kollox minn tipi tad-data
li conditionals li għal loops.

1050
00:36:09,670 --> 00:36:10,620
Loops b'mod ġenerali.

1051
00:36:10,620 --> 00:36:14,360
>> SHARON: U fl-aħħar, aħna
se tagħti ħarsa lejn P sett wieħed,

1052
00:36:14,360 --> 00:36:16,739
u dak li inti għandek tkun taf għal dan.

1053
00:36:16,739 --> 00:36:18,030
Mela ejja nibdew mal-tipi ta 'data.

1054
00:36:18,030 --> 00:36:19,840

1055
00:36:19,840 --> 00:36:23,230
You guys għandhom ikunu familjari mal-
dawk li huma enfasizzati fil-blu.

1056
00:36:23,230 --> 00:36:25,340
Allura nistgħu tibda bil ints.

1057
00:36:25,340 --> 00:36:31,500
ints huma interi, hekk wieħed, tnejn,
tlieta, erbgħa. sufruni, punti f'wiċċ l-ilma.

1058
00:36:31,500 --> 00:36:37,830
Bħal interi bl deċimali,
hekk 5.2 jew saħansitra 5.0.

1059
00:36:37,830 --> 00:36:44,230
Chars huma karattri bħal A, B, Ċ
U string, inti guys kollha jafu.

1060
00:36:44,230 --> 00:36:48,470
Bħal CS50 jew Hello u fid-dinja.

1061
00:36:48,470 --> 00:36:50,290

1062
00:36:50,290 --> 00:36:56,890
>> BOOL hija Boolean, hekk aħna
vera u falza bħala Boolean tagħna.

1063
00:36:56,890 --> 00:37:01,550
Mela jekk xi ħaġa jikkalkula li truth--
5 ugwali 5, li jikkalkula li veru,

1064
00:37:01,550 --> 00:37:06,470
u jekk ikollna 5 ugwali 4, li l-
falza, b'tali mod li jikkalkula li falza.

1065
00:37:06,470 --> 00:37:12,280
U hawn aħna għandna l-assoċjati
daqs ta 'kollha ta' dawn it-tipi ta 'data.

1066
00:37:12,280 --> 00:37:14,860
U inti ser ikollok tkun taf
dan għall kwizzijiet tiegħek,

1067
00:37:14,860 --> 00:37:18,412
għalhekk dan jista 'jkun utli li
ftakar, iżda aħna ser post dawn.

1068
00:37:18,412 --> 00:37:19,745
Attwalment dawn qed diġà stazzjonati.

1069
00:37:19,745 --> 00:37:21,921

1070
00:37:21,921 --> 00:37:24,420
Allura inti għandek tkun familjari ma '
dawk enfasizzati fil-blu.

1071
00:37:24,420 --> 00:37:27,900

1072
00:37:27,900 --> 00:37:30,580
>> JASON Hirschhorn: Real
malajr, biss fil-każ li inti

1073
00:37:30,580 --> 00:37:34,096
trid tkun taf id-differenza
bejn char u string.

1074
00:37:34,096 --> 00:37:45,020
Allura meta int bil-miktub Jittieħed,
kull meta inti għandek xi ħaġa bħal "hi,"

1075
00:37:45,020 --> 00:37:46,340
li għaddej biex tkun string.

1076
00:37:46,340 --> 00:37:48,090
Mela jekk ikun hemm tnejn
kwotazzjonijiet, huwa string.

1077
00:37:48,090 --> 00:37:52,890
Imma jekk jien kienu għal "h"
bħal dik, li l-string.

1078
00:37:52,890 --> 00:37:55,759
Imma jekk jien biss jkollhom waħda
kwotazzjoni, li l-char.

1079
00:37:55,759 --> 00:37:57,550
U hekk x'inhu l-
differenza tista 'titlob.

1080
00:37:57,550 --> 00:38:00,985
Ukoll, id-differenza hija
dan huwa byte wieħed ta 'memorja.

1081
00:38:00,985 --> 00:38:02,265
Dan huwa ta '4 bytes ta' memorja.

1082
00:38:02,265 --> 00:38:09,480

1083
00:38:09,480 --> 00:38:10,520

1084
00:38:10,520 --> 00:38:12,180
Iddeskrivi ġdid?

1085
00:38:12,180 --> 00:38:18,200
OK, huwa tip simili ta 'numru
li għandu punt deċimali magħha,

1086
00:38:18,200 --> 00:38:27,569
hekk 5.2 jew saħansitra 5.0 huwa float
versus biss 5 huwa int.

1087
00:38:27,569 --> 00:38:28,444
STUDENT: [inaudible].

1088
00:38:28,444 --> 00:38:30,240

1089
00:38:30,240 --> 00:38:36,301
>> SHARON: Oh, dan jista 'jkollu ħafna
punti deċimali, hekk 5.675-3.1415.

1090
00:38:36,301 --> 00:38:36,800
Iva?

1091
00:38:36,800 --> 00:38:39,716
>> STUDENT: Do għandna bżonn tkun taf
l-daqsijiet kollha għal dan?

1092
00:38:39,716 --> 00:38:40,216
SHARON: Iva.

1093
00:38:40,216 --> 00:38:41,293

kurżità, hemm utilità

1099
00:38:56,432 --> 00:39:00,424
li jkunu jafu l-daqs tal-fajls int
sejħa sabiex inkunu għandek tkun taf dan?

1100

1101
00:39:01,430 --> 00:39:04,330
>> SHARON: Allura dawn huma
tip ta 'data, iżda iva.

1102
00:39:04,330 --> 00:39:09,820
Allura f'dan il-każ, li wieħed ikun
jieħdu memorja aktar jew aktar spazju?

1103
00:39:09,820 --> 00:39:13,940
>> JASON Hirschhorn: So
għal eżempju konkret,

1104
00:39:13,940 --> 00:39:16,904
fil Naħseb sett problema
erba 'jew ħamsa, aħna qed

1105
00:39:16,904 --> 00:39:19,070
ser jagħtuk mazz
ta 'data, u inti bażikament

1106
00:39:19,070 --> 00:39:20,710
għandek travers dik id-data.

1107
00:39:20,710 --> 00:39:24,470
Allura huwa utli li tkun taf li
jekk għandek tant interi,

1108
00:39:24,470 --> 00:39:25,770
li għaddej biex jkun dak.

1109
00:39:25,770 --> 00:39:28,802
Mela ejja ngħidu I ħadt għaxar
interi, x'inhu l-daqs ta 'dak?

1110
00:39:28,802 --> 00:39:30,111

1111
00:39:30,111 --> 00:39:30,610
STUDENT: 40.

1112
00:39:30,610 --> 00:39:32,026
JASON Hirschhorn: 40 bytes, id-dritt.

1113
00:39:32,026 --> 00:39:35,690
Allura inti jista 'jkollok bżonn li tkun taf li
OK, I bżonn li tiżdied 40 bytes.

1114
00:39:35,690 --> 00:39:42,200
Mela ejja ngħidu minflok huwa 40 Chars,
then-- ejja ngħidu jiena ħadt 10 Chars,

1115
00:39:42,200 --> 00:39:44,860
imbagħad inti taf, OK, I biss
bżonn li tiżdied 10 bytes.

1116
00:39:44,860 --> 00:39:47,651
Allura huwa utli ħafna li jkunu jafu l-
daqs tat-tipi ta 'dejta attwali,

1117
00:39:47,651 --> 00:39:49,900
għaliex il-darba lott tkun taf
jiġu jaqbeż madwar id-dejta,

1118
00:39:49,900 --> 00:39:51,399
sabiex inti jeħtieġ li tkun taf kemm li jaqbżu.

1119

>> JASON Hirschhorn: OK,
żewġ kwotazzjonijiet hija sekwenza.

1122
00:39:58,670 --> 00:40:00,423
Wieħed kwotazzjoni hija char.

1123
00:40:00,423 --> 00:40:03,570
>> STUDENT: Bħal operazzjonalment,
x'inhu l-differenza?

1124
00:40:03,570 --> 00:40:04,466
Huma t-tnejn jgħidu hi.

1125
00:40:04,466 --> 00:40:05,094

1126
00:40:05,094 --> 00:40:06,260
JASON Hirschhorn: Oh, sorry.

1127
00:40:06,260 --> 00:40:07,870
Dan huwa biss h.

1128
00:40:07,870 --> 00:40:09,585
Jiddispjacini, dan ma jkunx ċar.

1129

1130
00:40:10,920 --> 00:40:12,412
>> STUDENT: Allura l-quċċata one--

1131
00:40:12,412 --> 00:40:14,120
JASON Hirschhorn: Dan
huwa string, yeah.

1132
00:40:14,120 --> 00:40:15,430
Allura huwa żewġ karattri, id-dritt?

1133
00:40:15,430 --> 00:40:16,360
Spag, hi.

1134
00:40:16,360 --> 00:40:19,030
Imma ejja ngħidu I biss
kellha karattru wieħed,

1135
00:40:19,030 --> 00:40:23,220
jekk nressaq żewġ kwotazzjonijiet madwar
biss h, li l-string.

1136
00:40:23,220 --> 00:40:24,500
Din hija string h.

1137
00:40:24,500 --> 00:40:25,660

1138
00:40:25,660 --> 00:40:26,940
Ma li jagħmel sens?

1139
00:40:26,940 --> 00:40:28,705
Allura dan huwa erba 'bytes.

1140
00:40:28,705 --> 00:40:31,660
Imma ejja ngħidu I ħassar
ta 'dak l tpoġġi wieħed biss.

1141
00:40:31,660 --> 00:40:33,940

1142
00:40:33,940 --> 00:40:34,830
Wieħed kwotazzjoni.

1143
00:40:34,830 --> 00:40:37,140
Dan issa huwa char, char h.

00:40:37,140 --> 00:40:38,440

1145
00:40:38,440 --> 00:40:42,410
Allura istess ħaġa eżatt,
tip ta 'data differenti.

1146
00:40:42,410 --> 00:40:45,330
Dan huwa byte wieħed biss, billi
il-sekwenza kien erba 'bytes.

1147
00:40:45,330 --> 00:40:45,830
Yeah.

1148
00:40:45,830 --> 00:40:48,214

li taħżen kelma bħal David,

1150

inti tixtieq li tuża string għaliex
irrispettivament minn kemm żmien il-sekwenza huwa,

1151
00:40:54,436 --> 00:40:57,760
se jieħu biss erba 'bytes
sakemm huwa twil twil

1152
00:40:57,760 --> 00:41:02,530
jew doppja, li fiha case-- hekk jekk
jestendi lil hinn erba 'karattri, imbagħad

1153
00:41:02,530 --> 00:41:04,435
inti tixtieq li tagħmel dan fil string.

1154
00:41:04,435 --> 00:41:05,810
Huwa li l-loġika ġenerali.

kelma bħala tliet karattri individwali

1160
00:41:18,370 --> 00:41:22,050
minħabba li se jkun biss tliet bytes,
kif oppost għad-sekwenza parti tlieta.

1164
00:41:27,850 --> 00:41:31,070
Inti tista 'tagħmel dan, imma jien ma
jaħsbu li tassew utli,

00:41:31,070 --> 00:41:32,570
għax int biss iffrankar byte wieħed.

1166
00:41:32,570 --> 00:41:33,310
Inti taf dak li jien tgħid?

1167
00:41:33,310 --> 00:41:35,559
Fl-iskema ta 'affarijiet kbar,
li mhux se verament kwistjoni.

1168

1170
00:41:43,430 --> 00:41:47,680
inti tista 'jistampa qattus biss billi
tagħmel char waħda char waħda char waħda,

1171
00:41:47,680 --> 00:41:49,980
jew inti tista 'jistampa qattus string.

1172
00:41:49,980 --> 00:41:51,140
Huwa l-istess ħaġa eżatt.

1173
00:41:51,140 --> 00:41:52,870
Allura inti tista 'tagħmel dan bħal dik, but--

1174
00:41:52,870 --> 00:41:54,330
>> STUDENT: Mhuwiex għaddej
biex tiffranka li ħafna.

1175
00:41:54,330 --> 00:41:54,720
>> JASON Hirschhorn: Yeah.

1176
00:41:54,720 --> 00:41:57,125
L-ras li dan iwassal
jinduċi huwa mhux worth it.

1177
00:41:57,125 --> 00:41:59,049

1178
00:41:59,049 --> 00:42:00,020
Yeah?

1179
00:42:00,020 --> 00:42:02,920
>> STUDENT: Per eżempju,
kellek il-h ma 'wieħed

1180
00:42:02,920 --> 00:42:05,410
versus tnejn, il-kwotazzjonijiet wieħed jew doppju.

1181
00:42:05,410 --> 00:42:08,760
Għaliex kieku inti tixtieq li jiffrankaw
ittra waħda bħala string.

1182
00:42:08,760 --> 00:42:11,569
Liema għan ma li qatt iservu?

1183
00:42:11,569 --> 00:42:12,860
JASON Hirschhorn: I do not know.

1184
00:42:12,860 --> 00:42:14,568
I mean, huwa verament
jiddependi fuq il-programm.

1185
00:42:14,568 --> 00:42:16,060

1186
00:42:16,060 --> 00:42:20,800
Per eżempju, I think aktar tard
inti ser tikseb fis-għalf linja ta 'kmand.

1187
00:42:20,800 --> 00:42:24,770
Hekk per eżempju, minflok me
inti titlob għal sorry integer--,

1188
00:42:24,770 --> 00:42:26,720
nista jitkellmu fis inti?

1189
00:42:26,720 --> 00:42:27,220
HANNAH: Iva.

1190
00:42:27,220 --> 00:42:30,660

1191
00:42:30,660 --> 00:42:32,450
>> JASON Hirschhorn: So
per eżempju, minflok

1192
00:42:32,450 --> 00:42:35,830
ta 'lili tistaqsi għal xi ħaġa
b'tarf get, li

1193
00:42:35,830 --> 00:42:38,854
Naħseb li inti tista raw lecture,
jista 'jkun hemm linja ta' kmand.

1194
00:42:38,854 --> 00:42:40,520
Inti biss tip fil fil-linja tal-kmand.

1195
00:42:40,520 --> 00:42:46,690
Ikun simili - / hello4 jew
xi ħaġa, jew h helloh, ikun x'ikun.

1196
00:42:46,690 --> 00:42:49,190
Inti tagħmel dan fil-linja tal-kmand
minflok jiġu mitluba għal dan,

1197
00:42:49,190 --> 00:42:53,830
dik il-linja kmand huwa dejjem
string, kemm jekk huwa ta 'erba jew h,

1198
00:42:53,830 --> 00:42:55,320
li huwa dejjem string.

1199
00:42:55,320 --> 00:42:59,130
Allura dak eżempju wieħed ta 'meta inti tista
jkollu ittra singular jew singular

1200
00:42:59,130 --> 00:43:00,667
Numru rappreżentati kif string.

1201
00:43:00,667 --> 00:43:06,360

1202
00:43:06,360 --> 00:43:07,110
SHARON: Kull dritt.

1203
00:43:07,110 --> 00:43:08,230

1204
00:43:08,230 --> 00:43:09,855
U allura hawn huma xi operaturi bażiċi.

1205
00:43:09,855 --> 00:43:11,460

1206
00:43:11,460 --> 00:43:14,560
Nisperaw int familjari ma '
l-ewwel erba 'biss b'mod ġenerali.

1207
00:43:14,560 --> 00:43:18,080
Allura hemm żieda, tnaqqas,
multiplikazzjoni, u jiġi diviż,

1208
00:43:18,080 --> 00:43:23,535
u aċċerta ruħek li tuża
l-keystrokes dritt.

1209
00:43:23,535 --> 00:43:25,260

1210
00:43:25,260 --> 00:43:29,640
>> U allura hemm modulo ukoll, li xi
inti tista 'ma tkun familjari ħafna ma.

1211
00:43:29,640 --> 00:43:34,900
U dak modulo ma huwa li
jekk nieħdu dan l-eżempju 4% 2,

1212
00:43:34,900 --> 00:43:37,990
dan jieħu l-bqija tal-
dak li ma fid-diviżjoni.

1213
00:43:37,990 --> 00:43:41,670
Allura 4 diviż bil 2 huwa 2,
u hemm ebda bqija.

1214
00:43:41,670 --> 00:43:47,880
4 iddividi 3 hija l-1 u
03/01, u għalhekk kumplament 1.

1215
00:43:47,880 --> 00:43:49,320
Għalhekk jikkalkula li wieħed.

1216
00:43:49,320 --> 00:43:56,960
U mbagħad 4% 5 huwa l-frazzjoni
4/5, u l-bqija huwa ta '4.

1217
00:43:56,960 --> 00:43:58,580
Ma li jagħmel sens?

1218
00:43:58,580 --> 00:43:59,580
OK, berred.

1219
00:43:59,580 --> 00:44:01,080

1220
00:44:01,080 --> 00:44:03,110
U nimxu wara PEMDAS hawnhekk ukoll.

1221
00:44:03,110 --> 00:44:06,240

1222
00:44:06,240 --> 00:44:07,740
>> Għalhekk xi espressjonijiet Boolean.

1223
00:44:07,740 --> 00:44:08,920

1224
00:44:08,920 --> 00:44:16,890
Allura inti guys raw ugwali ugwali
li jqabbel, jiġifieri, żewġ numri.

1225
00:44:16,890 --> 00:44:20,440
Mela jekk 5 ugwali ugwali 5,
li jikkalkula li veru.

1226
00:44:20,440 --> 00:44:22,190
Kun ċert li jkollok wieħed biss ugwali sinjal.

1227
00:44:22,190 --> 00:44:23,530

1228
00:44:23,530 --> 00:44:27,030
Għal mhux ugwali, huwa
bang jew exclamation.

1229
00:44:27,030 --> 00:44:28,960
>> Hannah: Żewġ sinjali indaqs
meta inti tagħmel l-ugwaljanza.

1230
00:44:28,960 --> 00:44:29,290
>> SHARON: Oh, yeah.

1231
00:44:29,290 --> 00:44:30,998
Kun żgur li inti ma
jkollhom waħda ugwali sinjal.

1232
00:44:30,998 --> 00:44:32,320

1233
00:44:32,320 --> 00:44:35,745
U mbagħad għal mhux ugwali,
huwa bang ugwali.

1234
00:44:35,745 --> 00:44:37,000

1235
00:44:37,000 --> 00:44:40,540
U allura inti tista 'tfittex permezz
għal inqas minn, akbar minn.

1236
00:44:40,540 --> 00:44:44,300
U allura għandna loġiku u
u loġiku jew dritt hawn.

1237
00:44:44,300 --> 00:44:47,190
U dak li ma hu, jekk
tiftakar fil Scratch

1238
00:44:47,190 --> 00:44:51,000
meta kellek li jimblukkaw
li qal u, u allura inti

1239
00:44:51,000 --> 00:44:54,860
tista 'toqgħod tajjeb żewġ biċċiet differenti
hemm, dan huwa dak dan u ma.

1240
00:44:54,860 --> 00:44:56,450
U aċċerta ruħek li tagħmel żewġ ampersands.

00:44:56,450 --> 00:44:57,590

1242
00:44:57,590 --> 00:45:04,110

thats jitqabblu xi ħaġa oħra.

1251

Allura bħal int x ugwali 4.

1254
00:45:33,170 --> 00:45:38,080
Inti qed tgħid li x-varjabbli ugwali 4.

1255
00:45:38,080 --> 00:45:42,910
Allura 1 ugwali huwa assenjazzjoni,
iżda l-ANDS u l-pajpijiet

1256
00:45:42,910 --> 00:45:45,820
jew il-bars, bħad Sharon
qal, dawn qed operaturi bitwise.

per eżempju, ejja ngħidu I jridu jiċċekkjaw
li numru huwa bejn 5 u 15,

1263

1322
00:48:28,630 --> 00:48:32,090
jew talab il-ħin, or--
kull ħaġ'oħra ma dan l-eżempju?

1323
00:48:32,090 --> 00:48:33,560

1324
00:48:33,560 --> 00:48:34,060
Biża.

1325
00:48:34,060 --> 00:48:35,750

1326
00:48:35,750 --> 00:48:40,490
>> OK, issa għandna b'żieda
għal dik sempliċi jekk format ieħor,

1327
00:48:40,490 --> 00:48:42,899
għandna żewġ strutturi differenti oħra.

1328
00:48:42,899 --> 00:48:44,940
Allura l-ewwel għandna l-iswiċċ
dikjarazzjoni, u hawnhekk

1329
00:48:44,940 --> 00:48:46,564
l-forma ġenerali ta 'dikjarazzjoni swiċċ.

1330
00:48:46,564 --> 00:48:49,450

1331
00:48:49,450 --> 00:48:53,110
Inti għandek l-keyword jaqilbu l-
istess mod inti għandek l-keyword jekk.

1332
00:48:53,110 --> 00:48:56,250
U mbagħad input, f'dan il-każ n.

1333
00:48:56,250 --> 00:48:58,410
Allura dan jista 'jaħdem biss ma' interi.

1334
00:48:58,410 --> 00:49:02,270
Allura li l-input n ikollu
li jkun integer, OK?

1335
00:49:02,270 --> 00:49:04,950
U aħna qed tmur biex
jsegwi waħda minn dawn il-każijiet

1336
00:49:04,950 --> 00:49:07,430
jiddependi fuq dak li l-valur n huwa.

1337
00:49:07,430 --> 00:49:12,170
>> Allura f'dan il-każ, inti l-ewwel tqabbel
huwa n ugwali għal wieħed kostanti,

1338
00:49:12,170 --> 00:49:15,844
jekk huwa, tagħmel dak kollu
tip ta 'indentata hawn fuq.

1339
00:49:15,844 --> 00:49:17,510
I jista 'jiġbed l għaliex jien qasir wisq.

1340
00:49:17,510 --> 00:49:19,400

1341
00:49:19,400 --> 00:49:23,210
Jekk mhuwiex ugwali għal wieħed kostanti
u huwa minflok ugwali għal kostanti tnejn,

1342
00:49:23,210 --> 00:49:27,060
aħna qed tmur biex isegwu dan it-tieni blokk,
u nistgħu nagħmlu dan għal kemm il-darba

1343
00:49:27,060 --> 00:49:32,890
kif irridu, u mbagħad li default jekk
hija ma taqbilx ma kwalunkwe mill-każijiet imsemmija hawn fuq,

1344
00:49:32,890 --> 00:49:33,820
tesegwixxi dan il-kodiċi.

1345
00:49:33,820 --> 00:49:35,759

1346
00:49:35,759 --> 00:49:36,550
Kwalunkwe mistoqsijiet hawn?

1347
00:49:36,550 --> 00:49:38,133
Dan huwa wieħed ftit aktar kumplikata.

1348
00:49:38,133 --> 00:49:38,633

1349
00:49:38,633 --> 00:49:39,395
Yeah?

1350
00:49:39,395 --> 00:49:41,820
>> STUDENT: Break li tfisser dak?

1351
00:49:41,820 --> 00:49:45,560
>> HANNAH: Sure, hekk darba aħna jidħol
li blokk, jekk insibu, ejja ngħidu,

1352
00:49:45,560 --> 00:49:50,940
n tagħna hija fil-fatt ugwali għal wieħed kostanti,
aħna jidħol li jimblukkaw wara l-kolon.

1353
00:49:50,940 --> 00:49:54,840
We do dak kollu li huwa fuq
dik il-linja ta 'kummentarju,

1354
00:49:54,840 --> 00:49:58,182
u allura aħna break, li jfisser irridu jiksbu out
ta 'din id-dikjarazzjoni swiċċ kompletament.

1355
00:49:58,182 --> 00:49:58,682
STUDENT: OK.

1356
00:49:58,682 --> 00:49:59,830

1357
00:49:59,830 --> 00:50:00,562
>> HANNAH: Mm-hm?

1358
00:50:00,562 --> 00:50:03,311
>> STUDENT: Huwa l-indentazzjoni
meħtieġ, jew għandek bżonn [inaudible]?

1359
00:50:03,311 --> 00:50:03,959

1360
00:50:03,959 --> 00:50:04,500
HANNAH: Sure.

1361
00:50:04,500 --> 00:50:07,640
Allura, kif dejjem, indentazzjoni
mhuwiex strettament neċessarju.

1362
00:50:07,640 --> 00:50:09,930
Il-kompjuter ma
kura jekk inti inċiż.

1363
00:50:09,930 --> 00:50:12,630
Aħna, bħala nies li huma
qari kodiċi tiegħek, do kura.

1364
00:50:12,630 --> 00:50:15,100
Allura huwa ħafna aktar faċli biex
ħarsa up fuq l-iskrin

1365
00:50:15,100 --> 00:50:19,707
u ara, oh, I jafu eżattament liema
jiġri meta n huwa daqs wieħed kostanti.

1366
00:50:19,707 --> 00:50:22,290
Jekk kelli inċiżi każwali, I
ma tkunx kapaċi li tgħid daqshekk faċilment.

1367
00:50:22,290 --> 00:50:23,276
Yeah?

1368
00:50:23,276 --> 00:50:27,466
>> STUDENT: Mela jekk riedu utent biex
jagħżlu waħda mill-għażliet li

1369
00:50:27,466 --> 00:50:31,657
għandna fuq il-lista, kieku
nużaw, I raden, [inaudible],

1370
00:50:31,657 --> 00:50:35,108
iżda jiksbu integer minn
minnhom u li jitqiegħdu fis n?

1371
00:50:35,108 --> 00:50:36,844

1372
00:50:36,844 --> 00:50:37,760
HANNAH: Eżattament dritt.

1373
00:50:37,760 --> 00:50:40,330
Mela ejja ngħidu ridna
biex jiċċekkjaw liema numru sħiħ.

1374
00:50:40,330 --> 00:50:45,380
Aħna qal oh, jidħol integer
bejn 0 u 5, ejja ngħidu.

1375
00:50:45,380 --> 00:50:47,790
Nistgħu jistaqsu għal dak
n, titlob għal dak il-valur,

1376
00:50:47,790 --> 00:50:50,000
u mbagħad ikollhom kull wieħed minn dawk il-każijiet.

1377
00:50:50,000 --> 00:50:53,230
U għal darb'oħra, din hija xi ħaġa nistgħu
faċilment jagħmlu ma jekk id-dikjarazzjonijiet,

1378
00:50:53,230 --> 00:50:53,730
dritt?

1379
00:50:53,730 --> 00:50:56,920
Jista 'jkollna jekk daqs każ
wieħed, jekk daqs każ tnejn,

1380
00:50:56,920 --> 00:50:58,910
jekk daqs każ tlieta,
hekk u ibqa 'sejjer hekk.

1381
00:50:58,910 --> 00:51:01,680
Dan huwa ftit aktar mgħaġġel
u nadifa ftit.

1382
00:51:01,680 --> 00:51:04,201
Huwa tip ta 'ftit struttura sbieħ issa.

1383
00:51:04,201 --> 00:51:05,450
STUDENT: Faster kif bil-miktub?

1384
00:51:05,450 --> 00:51:06,830
Jew ma imexxu l-
kompjuter ftit aktar mgħaġġel?

1385
00:51:06,830 --> 00:51:08,246
>> HANNAH: Huwa runs ftit aktar mgħaġġel.

1386
00:51:08,246 --> 00:51:09,214

1387
00:51:09,214 --> 00:51:09,714
Yeah?

1388
00:51:09,714 --> 00:51:13,490
>> STUDENT: Allura l-double
sing huwa biss jikkummentaw or--

1389
00:51:13,490 --> 00:51:14,700
>> HANNAH: Oh, jien so sorry.

1390
00:51:14,700 --> 00:51:15,700
I ma jsostnu dan.

1391
00:51:15,700 --> 00:51:17,790
OK, jekk ikollok li //, huwa kumment.

1392
00:51:17,790 --> 00:51:19,250

1393
00:51:19,250 --> 00:51:20,770
Just // huwa kumment.

1394
00:51:20,770 --> 00:51:23,030
Sabiex kwalunkwe ħin il-kompjuter
jara li, li għaddej

1395
00:51:23,030 --> 00:51:25,760
ngħid OK, xi ħaġa li ġej
dan, jien biss ser jinjoraw.

1396
00:51:25,760 --> 00:51:27,310
Jien ser nippretendu int
qatt ma kiteb li.

1397
00:51:27,310 --> 00:51:28,850
>> STUDENT: Allura dan [inaudible].

1398
00:51:28,850 --> 00:51:30,650
>> HANNAH: Dan ma assolutament xejn.

1399
00:51:30,650 --> 00:51:37,360
Imma jekk I kiteb xi ħaġa simili fuq il-
ewwel kumment I kiteb minflok printf

1400
00:51:37,360 --> 00:51:41,640
jgħidu congratulations tkun daħħalt
wieħed kostanti, li tkun xi ħaġa.

1401
00:51:41,640 --> 00:51:42,140
Yeah?

1402
00:51:42,140 --> 00:51:44,515
>> STUDENT: Allura fil-ħajja reali, il-
każ ikun biss sempliċement tkun numru

1403
00:51:44,515 --> 00:51:46,420
u mbagħad [inaudible]
ikun numru sħiħ ieħor.

1404
00:51:46,420 --> 00:51:46,763
>> HANNAH: Eżattament.

1405
00:51:46,763 --> 00:51:48,550
>> STUDENT: U ma għandek bżonn l-elissi?

1406
00:51:48,550 --> 00:51:48,805
>> HANNAH: Jiddispjacini?

1407
00:51:48,805 --> 00:51:49,550
>> STUDENT: Għandek bżonn li?

1408
00:51:49,550 --> 00:51:50,010
>> HANNAH: Oh, no.

1409
00:51:50,010 --> 00:51:50,560
Jien sorry.

1410
00:51:50,560 --> 00:51:53,684
Li kien biss li jindika li inti tista '
mur fuq għal kif ħafna każijiet kif tixtieq.

1411
00:51:53,684 --> 00:51:56,950
Ejja nagħmlu eżempju konkret li
tista 'tagħmel l-affarijiet ftit aktar ċara.

1412
00:51:56,950 --> 00:52:01,440
OK, so ejja ngħidu I say,
OK, tagħti me n integer

1413
00:52:01,440 --> 00:52:05,010
li jirrappreżenta numru tal-klassi,
speċifikament klassi xjenza tal-kompjuter

1414
00:52:05,010 --> 00:52:05,720
numru.

1415
00:52:05,720 --> 00:52:07,950
Mela jekk inti tagħti me 50,
Jien se ngħid kbira.

1416
00:52:07,950 --> 00:52:12,020
CS50 hija introduzzjoni għal kompjuter
xjenza, u mbagħad jien ser break.

1417
00:52:12,020 --> 00:52:14,810
Allura dan ifisser I jaqbżu out ta '
din id-dikjarazzjoni swiċċ kollu,

1418
00:52:14,810 --> 00:52:17,020
hekk issa jien jsir running-kodiċi, OK?

1419
00:52:17,020 --> 00:52:21,410
>> Jekk int tajt lili minflok 51, I d
jistampaw il-tieni dikjarazzjoni.

1420
00:52:21,410 --> 00:52:24,720
U mbagħad jekk inti tatni xi
numru li ma kienx 50 jew 51,

1421
00:52:24,720 --> 00:52:27,133
Jien se ngħid sorry, jien
ma jkunux familjari ma 'dik il-klassi.

1422
00:52:27,133 --> 00:52:28,019
Yeah?

1423
00:52:28,019 --> 00:52:29,350
>> STUDENT: Inti ma għandekx break.

1424
00:52:29,350 --> 00:52:30,400
>> HANNAH: Jien sorry, I ma jkollhomx break?

1425
00:52:30,400 --> 00:52:31,510
>> STUDENT: X'jiġri jekk.

1426
00:52:31,510 --> 00:52:32,450
>> HANNAH: Oh, dak li jekk
inti ma għandekx break?

1427
00:52:32,450 --> 00:52:33,450
Eċċellenti kwistjoni.

1428
00:52:33,450 --> 00:52:37,890
Allura x'jista 'jiġri huwa inti tmur fi,
u inti tiċċekkja am I ugwali għal 50?

1429
00:52:37,890 --> 00:52:42,064
U ejja ngħidu, iva, inti kienu ugwali
50, youd jistampaw l-istqarrija.

1430
00:52:42,064 --> 00:52:45,105
U allura inti se jibqgħu eżekuzzjoni,
sabiex inti ngħid jien ugwali għal 51?

1431
00:52:45,105 --> 00:52:46,500

1432
00:52:46,500 --> 00:52:49,763
U inti tmur fuq u jmorru
permezz ta 'kull każ bħal dik?

1433
00:52:49,763 --> 00:52:50,262
Iva?

1434
00:52:50,262 --> 00:52:52,894
>> STUDENT: Huwa l-linja default
analogi għal qal ħaġa oħra?

1435
00:52:52,894 --> 00:52:53,560
HANNAH: Eżattament.

1436
00:52:53,560 --> 00:52:54,060
Tajba ħafna.

1437
00:52:54,060 --> 00:52:56,140
Huwa bħall-tip ta 'qabda kollha.

1438
00:52:56,140 --> 00:53:00,574
>> STUDENT: Mela jekk inti ma kellhiex waqfa
u mbagħad wieħed mill-istqarrijiet każ

1439
00:53:00,574 --> 00:53:03,843
kien veru, u mbagħad
qal żieda n b'1,

1440
00:53:03,843 --> 00:53:09,210
allura awtomatikament
jagħmlu dak li jmiss.

1441
00:53:09,210 --> 00:53:11,657
Ikun tiċċekkja każ 51, u
mbagħad juru dan ukoll?

1442
00:53:11,657 --> 00:53:13,240
HANNAH: Yeah, naħseb li tkun taħdem.

1443
00:53:13,240 --> 00:53:15,740
Allura inti tista 'tip ta' nikseb messy, hekk
waqfa hija ħaġa tajba li jkollhom.

1444
00:53:15,740 --> 00:53:16,240
Yeah?

1445
00:53:16,240 --> 00:53:18,557
STUDENT: Mingħajr break
ikun jidher jagħmlu l-default?

1446
00:53:18,557 --> 00:53:19,890
HANNAH: Din hija mistoqsija tajba.

1447
00:53:19,890 --> 00:53:20,590
JASON Hirschhorn: Naħseb li biss runs.

1448
00:53:20,590 --> 00:53:23,975
Hekk jekk inti ma għandekx break-- hekk
ejja ngħidu I ma 50 u hija vverifikat 50,

1449
00:53:23,975 --> 00:53:25,306
u kien jistampa li minn.

1450
00:53:25,306 --> 00:53:27,430
Jistampa CS50 bħala introduzzjoni
għax-xjenza tal-kompjuter.

1451
00:53:27,430 --> 00:53:30,549
Inti ma għandekx break, għandhom imorru
u jibqgħu għaddejjin sakemm hits pawża.

1452
00:53:30,549 --> 00:53:32,590
Hekk jekk hemm l-ebda waqfa,
li għaddej biex jibqgħu għaddejjin.

1453
00:53:32,590 --> 00:53:34,190
Li għaddej biex jistampa kollox out.

1454
00:53:34,190 --> 00:53:35,695
>> HANNAH: So I raden li kieku
jkun inkluż l-inadempjenza.

1455
00:53:35,695 --> 00:53:36,020
>> JASON Hirschhorn: Yeah.

1456
00:53:36,020 --> 00:53:36,720

1462
00:53:43,153 --> 00:53:45,520

1463
00:53:45,520 --> 00:53:46,840
I se taħsibha darbtejn biex ngħid li.

1464
00:53:46,840 --> 00:53:52,000
>> JASON Hirschhorn: Allura normalment
meta tara funzjonijiet

1465
00:53:52,000 --> 00:53:54,370
dawn ser ikunu fil braces kaboċċi.

1466
00:53:54,370 --> 00:53:57,840
Hekk per eżempju, meta inti tfittex
fil-kodiċi tiegħek, per eżempju, prinċipali.

1467
00:53:57,840 --> 00:54:01,450
Kien paren ewlenin miftuħa,
imbagħad null, paren qrib.

1468
00:54:01,450 --> 00:54:05,415
Functions-- dawn qed bażikament
dejjem tkun taf tara parentesi.

1469
00:54:05,415 --> 00:54:07,290
Mela każ jekk il-każ ma
xi parentesi,

1470

01:00:31,659 --> 01:00:33,950
JASON Hirschhorn: Meta tagħmel
taħseb li tista 'tuża dan?

1625
01:00:33,950 --> 01:00:35,480
Meta ma jagħmilx sens li jużaw dan?

1626
01:00:35,480 --> 01:00:36,839

1627
01:00:36,839 --> 01:00:37,380

JASON Hirschhorn: Dritt.

1631
01:00:41,080 --> 01:00:41,575
HANNAH: Tajjeb ħafna.

1632
01:00:41,575 --> 01:00:43,408
JASON Hirschhorn: So
meta inti utent pront,

1633
01:00:43,408 --> 01:00:45,947
int ser dejjem trid
biex fil-pront utent darba.

1634
01:00:45,947 --> 01:00:48,280
Inti dejjem tmur jridu
biex tkun inkoraġġuta l-utent f'ħin wieħed.

1635
01:00:48,280 --> 01:00:50,103
Allura minflok ta 'tqegħid
fil-linja waqt, inti

1636
01:00:50,103 --> 01:00:52,820
jitqiegħdu fil tagħmel waqt loop, għax int
dejjem se tagħmel dan darba.

1637
01:00:52,820 --> 01:00:54,730
Jekk huma jagħtuk l-
risposta korretta, inti qed isir.

1638
01:00:54,730 --> 01:00:56,355
Jekk huma ma jagħmlux hekk, allura inti jerġgħu twassalhom.

1639
01:00:56,355 --> 01:01:02,080

1640

1642
01:01:05,830 --> 01:01:08,590
Allura fil Scratch, kellna blokki ripetuti.

1643
01:01:08,590 --> 01:01:12,640
Hekk ridna li jirrepetu xi ħaġa,
ejja ngħidu, seba 'darbiet.

1644
01:01:12,640 --> 01:01:16,580
Allura aħna biss qal jirrepetu seba, u
ngħid jien hawn biex jgħinuk Snow White!

1645
01:01:16,580 --> 01:01:18,590

1646
01:01:18,590 --> 01:01:22,550
Fil C, għandna għal linji jekk aħna
tixtieq li jgħaddu xi ħaġa

1647
01:01:22,550 --> 01:01:23,970
numru speċifiku ta 'drabi.

1648
01:01:23,970 --> 01:01:29,700
Ejja ngħidu jekk aħna initialize
l-dwarves varjabbli

1649
01:01:29,700 --> 01:01:35,410
u jagħmlu sure-- hekk l-ewwel blokk
hemm dritt qabel l-ewwel punt u virgola,

1650
01:01:35,410 --> 01:01:39,260
aħna initialize varjabbli tagħna
li, u aħna waqqafna dan għal 0.

1651
01:01:39,260 --> 01:01:41,850
U varjabbli tagħna hemm
huwa integer, int.

1652
01:01:41,850 --> 01:01:43,590

1653
01:01:43,590 --> 01:01:47,640
U l-isem varjabbli huwa
dwarves, u aħna waqqafna dwarves għal 0.

1654
01:01:47,640 --> 01:01:52,660
>> U t-tieni parti bejn l-
żewġ semicolons hija kundizzjoni tagħna.

1655
01:01:52,660 --> 01:01:53,720

1656
01:01:53,720 --> 01:01:58,630
U hekk sakemm dwarves
huwa inqas minn seba,

1657
01:01:58,630 --> 01:02:01,730
aħna ser iżommu għaddejjin dan għall loop.

1658
01:02:01,730 --> 01:02:06,350
U allura l-aħħar parti huwa dak do
nagħmlu fl-aħħar ta dan għall loop?

1659
01:02:06,350 --> 01:02:12,480
dwarves ++, u dan ifisser li aħna
inkrement dwarves minn wieħed kull darba.

1660
01:02:12,480 --> 01:02:13,900
>> Allura dak li jiġri hawn?

1661
01:02:13,900 --> 01:02:15,860

1662
01:02:15,860 --> 01:02:17,620
Allura l-ewwel aħna qed tmur biex jgħaddu.

1663
01:02:17,620 --> 01:02:19,690
Għandna dwarves bħala 0,
u allura aħna qed tmur

1664
01:02:19,690 --> 01:02:22,845
li jistampaw Ninsab hawn biex
jgħinek Snow White!

1665
01:02:22,845 --> 01:02:24,120

1666
01:02:24,120 --> 01:02:27,197
U mbagħad dwarves se
tiżdied għaliex aħna qal dwarves ++.

1667
01:02:27,197 --> 01:02:28,409

1668
01:02:28,409 --> 01:02:29,450
Dwarves se tkun 1.

1669
01:02:29,450 --> 01:02:32,720
U allura aħna compare-- dwarves huwa 1.

1670
01:02:32,720 --> 01:02:35,900
Inqabblu li huwa dwarves inqas minn 7?

1671
01:02:35,900 --> 01:02:36,660
Iva.

1672
01:02:36,660 --> 01:02:38,320

Ninsab hawn biex jgħinuk Snow White!

1674
01:02:40,190 --> 01:02:44,490
U mbagħad dwarves isir
2, u mbagħad inqabblu.

1675
01:02:44,490 --> 01:02:46,621
Huwa 2 inqas dik 7?

1676
01:02:46,621 --> 01:02:47,120
Iva.

1677
01:02:47,120 --> 01:02:48,740
Aħna qed tmur biex iżommu għaddejjin.

1678

1684
01:03:07,280 --> 01:03:08,546
Allura nibdew il 0.

1685

Iva?

1686
01:03:09,046 --> 01:03:11,630
>> STUDENT: Allura dan huwa
differenti mill-do

1687
01:03:11,630 --> 01:03:13,920
għaliex dan ma print
fil-bidu fl-ewwel.

1688
01:03:13,920 --> 01:03:15,880
Allura inti tista 'tkompli l-istess ħaġa.

dwar il-loop waqt, id-dritt?

1697
01:03:34,210 --> 01:03:36,010
Allura l-do filwaqt loop
hija kemmxejn differenti

1698
01:03:36,010 --> 01:03:39,966
għaliex aħna jiggarantixxu mill-anqas

SHARON: Inti tista 'titlob li tagħmel dan.

1782
01:06:59,530 --> 01:07:00,191
STUDENT: OK.

1783
01:07:00,191 --> 01:07:02,190
SHARON: Imma inti
jkollhom biex tistidinha sabiex tagħmel dan.

1784
01:07:02,190 --> 01:07:03,231
Ma tagħmel dan għalik.

1785
01:07:03,231 --> 01:07:04,730

1786
01:07:04,730 --> 01:07:06,875
Jien jibża li jpoġġu imsielet tiegħi lura fl.

1787
01:07:06,875 --> 01:07:07,874

1788
01:07:07,874 --> 01:07:09,290
Jagħmlu dan fl-aħħar għall-applause.

1789
01:07:09,290 --> 01:07:10,090
Just kidding.

1790
01:07:10,090 --> 01:07:11,755
>> JASON Hirschhorn: Allura dak hu l-istess.

1791
01:07:11,755 --> 01:07:13,460
Allura initialize fil-quċċata.

1792
01:07:13,460 --> 01:07:15,360
Kundizzjoni, jistampa, it-tibdil.

1793
01:07:15,360 --> 01:07:22,482
Allura dan huwa eżattament l-istess bħal
li jekk xi ħadd jista 'jara li.

1794
01:07:22,482 --> 01:07:23,871

1795
01:07:23,871 --> 01:07:26,370
STUDENT: Għaliex ma inti għandek l-
virgola fuq l-ewwel linja?

1796
01:07:26,370 --> 01:07:27,657

1797
01:07:27,657 --> 01:07:28,240
SHARON: Fejn?

1798
01:07:28,240 --> 01:07:29,490
STUDENT: Wara l-ewwel linja.

1799
01:07:29,490 --> 01:07:31,976
SHARON: Wara l-4 fil-parentesi?

1800
01:07:31,976 --> 01:07:33,850
Għaliex irridu li jmorru
'permezz fis dan loop.

1801
01:07:33,850 --> 01:07:39,309
U jekk inti tagħti ħarsa lejn loops fil
ġenerali, dawn ma jkollhomx semicolons.

1802
01:07:39,309 --> 01:07:40,100
Mhuwiex prattiku.

1803
01:07:40,100 --> 01:07:45,160

1804
01:07:45,160 --> 01:07:46,240
Aħna tajba?

1805
01:07:46,240 --> 01:07:47,470
Wieħed aktar kwistjoni, żewġ aktar.

1806
01:07:47,470 --> 01:07:48,056
Yeah?

1807
01:07:48,056 --> 01:07:49,930
STUDENT: Dan jista 'jkun
ftit avvanzati,

1808
01:07:49,930 --> 01:07:52,840
iżda do dwarves jkollhom
differenti [inaudible]

1809
01:07:52,840 --> 01:07:54,780
minn varjabbli [inaudible].

1810
01:07:54,780 --> 01:07:57,421

1811
01:07:57,421 --> 01:07:58,170
SHARON: Tajjeb ħafna.

1812
01:07:58,170 --> 01:07:59,045
STUDENT: [inaudible].

1813
01:07:59,045 --> 01:08:00,480

1814
01:08:00,480 --> 01:08:02,456

Liema?

1817
01:08:04,422 --> 01:08:05,880
JASON Hirschhorn: Yeah, hekk ma.

1818
01:08:05,880 --> 01:08:08,965
Allura normalment l-ambitu ta '
xi ħaġa hija fl-braces kaboċċi.

1819
01:08:08,965 --> 01:08:10,216

1820
01:08:10,216 --> 01:08:12,340
Allura ambitu dejjem se
li jkun fil-braces kaboċċi,

1821
01:08:12,340 --> 01:08:14,850
iżda li ma tkunx tagħmel
ħafna sens għall-għall-loop

1822
01:08:14,850 --> 01:08:17,550
għaliex aħna initialized
dwarves f'dak Brace kaboċċi.

1823
01:08:17,550 --> 01:08:23,310
Allura normalment l-ambitu ta 'dwarves, li
varjabbli ma testendix passat li.

1824
01:08:23,310 --> 01:08:25,000
Dan huwa każ speċjali għalkemm.

1825
01:08:25,000 --> 01:08:28,080
Allura inti initialize dan
fi ħdan dawk parentesi,

1826
01:08:28,080 --> 01:08:30,600
u allura inti għandek l-ambitu aktar tard.

1827
01:08:30,600 --> 01:08:32,720
Każ hekk speċjali.

1828
01:08:32,720 --> 01:08:39,059
Huma ma għandu jkollhom li, u
li was-- Li jagħmel sens?

1829
01:08:39,059 --> 01:08:40,037
>> STUDENT: No

1830
01:08:40,037 --> 01:08:41,629
>> JASON Hirschhorn: I tista 'tmur fuqha.

1831
01:08:41,629 --> 01:08:43,170
Allura dak li huma inti xorta konfuż dwar?

1832
01:08:43,170 --> 01:08:47,200

barra l-formula wisq?

1834
01:08:48,439 --> 01:08:49,480
>> JASON Hirschhorn: No, no.

1835
01:08:49,480 --> 01:08:53,385
Allura l-ambitu ta 'dan huwa biss ġewwa l-
ċingi kaboċċi għall-għall-loop, yeah.

1836
01:08:53,385 --> 01:08:56,509

1837
01:08:56,509 --> 01:08:59,300

inti tista 'tuża xi mkien ieħor
Hemm mistoqsija waħda aktar?

01:09:09,529 --> 01:09:10,130
OK.

1842
01:09:10,130 --> 01:09:15,807

1845
01:09:17,660 --> 01:09:21,310
Allura hawnhekk eżempju ta 'fejn
nistgħu bejta a għal loop.

01:09:38,729 --> 01:09:39,787

1853
01:09:39,787 --> 01:09:40,286

huwa ta '0, aħna tipprintja din x.

1863

Ringiela għadu 0, iżda kolonna huwa wieħed.

1866
01:10:11,280 --> 01:10:13,760
U allura kolonna huwa 2,
u mbagħad kolonna hija ta '3.
