00:00:00,000 --> 00:00:00,340

2
00:00:00,340 --> 00:00:02,690
>> DAVID Malan: Ejja ngħidu aħna tixtieq tikteb
programm li tqanqal l-utent

3
00:00:02,690 --> 00:00:05,100
għal string u mbagħad tikkapitalizza
li string.

4
00:00:05,100 --> 00:00:09,000
Well, ejja nibdew ma 'xi familjari
kodiċi tiddikjara string imsejjaħ iu

5
00:00:09,000 --> 00:00:11,380
tassenja dan ir-ritorn
valur tal getstring.

6
00:00:11,380 --> 00:00:14,910
U ejja issa tipproċedi biex jtenni fuq
l-karattri f'dan string.

7
00:00:14,910 --> 00:00:16,000
Well, kif għandek tagħmel dan?

8
00:00:16,000 --> 00:00:19,350
Jirriżulta li string huwa biss
sekwenza ta 'karattri, iżda aktar

9
00:00:19,350 --> 00:00:23,320
suppost, string firxa ta '
karattri, li jfisser nistgħu nużaw

10
00:00:23,320 --> 00:00:27,590
bracket notazzjoni kwadru għall-indiċi fi
string u jiksbu fil-livell individwali

11
00:00:27,590 --> 00:00:28,680
karattri.

12
00:00:28,680 --> 00:00:30,980
>> Fi kliem ieħor, nistgħu
jagħmlu dan li ġej.

13
00:00:30,980 --> 00:00:36,730
Għal int, i gets 0, u n gets,
jgħidu, it-tul ta 'i, bl-użu

14
00:00:36,730 --> 00:00:37,530
funzjoni tagħna [? ħawwad?]

15
00:00:37,530 --> 00:00:38,630
[? linja,?]

16
00:00:38,630 --> 00:00:40,450
i huwa inqas minn n i + +.

17
00:00:40,450 --> 00:00:45,290
Fi kliem ieħor, ma 'din loop, aħna
se jtenni fuq l-ittri kollha n

18
00:00:45,290 --> 00:00:46,670
fis-sekwenza s.

19
00:00:46,670 --> 00:00:51,680
U fi ħdan dan loop, jien ser
jikkontrolla, jekk il-karattru i-th fil-s

20
00:00:51,680 --> 00:00:57,630
ikbar minn jew ugwali għal zghar a,
u l-karattru i-th huwa inqas jew

21
00:00:57,630 --> 00:01:02,370
ugwali għal lowercase c, allura nixtieq li
jipproċedi għall-kapitalizzazzjoni din l-ittra.

22
00:01:02,370 --> 00:01:08,030
Fi kliem ieħor, nixtieq li jistampa% c
bħala placeholder u sostitut għall-

23
00:01:08,030 --> 00:01:11,120
li placeholder s bracket i.

24
00:01:11,120 --> 00:01:14,390
>> Imma mbagħad I bżonn li jikkonvertu
bracket s i li uppercase.

25
00:01:14,390 --> 00:01:18,930
Biex tagħmel dan, I jistgħu sempliċiment naqqas
tkun xi tkun id-differenza hija bejn

26
00:01:18,930 --> 00:01:24,120
lowercase au kapital A. Well, I
fil-fatt jagħmlu jfakkru li l-kapital A hija

27
00:01:24,120 --> 00:01:27,160
65 fil ASCII, u zghar a huwa 97.

28
00:01:27,160 --> 00:01:29,210
Għalhekk id-differenza hija teknikament 32.

29
00:01:29,210 --> 00:01:31,620
So I jistgħu biss kodiċi hard 32 hawn.

30
00:01:31,620 --> 00:01:33,870
Imma jien ma jista 'neċessarjament
tiftakar dawn in-numri.

31
00:01:33,870 --> 00:01:37,250
>> U barra minn hekk, dak li jekk dawn
jvarjaw mill-kompjuter?

32
00:01:37,250 --> 00:01:38,520
X'aktarx dawn mhux qed.

33
00:01:38,520 --> 00:01:42,460
Iżda l-punt jibqa 'li nista' xorta
tiġġeneralizza dik l-espressjoni aritmetika

34
00:01:42,460 --> 00:01:46,550
biss bħala x'ikun id-differenza hija
bejn lowercase a u kapital A

35
00:01:46,550 --> 00:01:50,880
huwa dak li nixtieq li naqqas off minn
din l-ittra zghar partikolari.

36
00:01:50,880 --> 00:01:54,500
>> Issa, jekk din l-ittra partikolari
mhux zghar, I sempliċiment

37
00:01:54,500 --> 00:01:56,620
tixtieq li jistampaw it out.

38
00:01:56,620 --> 00:02:01,110
printf,% ċ bħala placeholder tiegħi,
bracket s i.

39
00:02:01,110 --> 00:02:05,150
Fil-qiegħ ta 'dan il-programm, ejja
sempliċiment jistampa newline sabiex tiegħi

40
00:02:05,150 --> 00:02:07,520
pront jidher fuq ġdida
linja tagħha stess.

41
00:02:07,520 --> 00:02:11,540
>> Ejja issa jiġbor dan il-programm
ma jagħmlu capitalize0.

42
00:02:11,540 --> 00:02:13,900
Ejja run ma capitalize0.

43
00:02:13,900 --> 00:02:17,190
U ejja tip fil-kelma bħal
bonjour kollha zghar.

44
00:02:17,190 --> 00:02:19,960
I nikseb lura HELLO fl uppercase
kif mistenni.

45
00:02:19,960 --> 00:02:25,210
Imma ejja tipprova test wieħed aktar, din id-darba
bl-isem tiegħi stess, D-A-V-I-D, iżda ma

46
00:02:25,210 --> 00:02:28,170
l-ewwel D kapitalizzat, biss fil-
każ I messed xi ħaġa up

47
00:02:28,170 --> 00:02:29,430
ma 'dik l-ewwel char.

48
00:02:29,430 --> 00:02:34,250
Ikteb, u D-A-V-I-D fil uppercase
huwa stampat ukoll.

49
00:02:34,250 --> 00:02:36,873
