1
00:00:00,000 --> 00:00:00,720

2
00:00:00,720 --> 00:00:03,190
>> DAVID J. Malan: Tuseme kwamba Ningependa
kutekeleza mpango huo papo kwa

3
00:00:03,190 --> 00:00:06,650
user kwa kamba na kisha kuendelea
capitalize mchango wao,

4
00:00:06,650 --> 00:00:09,790
kuwabadili barua yoyote lowercase
kwamba wao aina ya uppercase.

5
00:00:09,790 --> 00:00:11,770
Naam, hebu kwenda mbele na
kutekeleza mpango huo.

6
00:00:11,770 --> 00:00:18,760
>> Hebu kwanza ni pamoja na cs50.h ikifuatiwa
na ni pamoja na stdio.h.

7
00:00:18,760 --> 00:00:23,990
Na ili tuweze kutumia strlen,
hebu ni pamoja na string.h.

8
00:00:23,990 --> 00:00:29,860
>> Hebu ijayo kutangaza kuu kama int kuu utupu
na hebu sasa kuendelea na kuchochea

9
00:00:29,860 --> 00:00:31,600
user kwa kamba.

10
00:00:31,600 --> 00:00:34,840
Printf, hebu kuwashawishi
kwa baadhi ya pembejeo.

11
00:00:34,840 --> 00:00:36,460
Sasa hebu kutangaza string -

12
00:00:36,460 --> 00:00:37,630
Tutamwita s -

13
00:00:37,630 --> 00:00:44,010
na kuhifadhi katika ni matokeo ya wito
cs50 kazi maktaba GetString.

14
00:00:44,010 --> 00:00:48,850
>> Hebu sasa kuendelea na iterate juu ya kila
wa wahusika katika s, kutumia

15
00:00:48,850 --> 00:00:50,650
barua yoyote lowercase kwamba sisi kuona.

16
00:00:50,650 --> 00:00:53,630
Kwa int, i kupata 0.

17
00:00:53,630 --> 00:00:58,780
Hebu pia kutangaza n kama kuwa sawa na
kamba urefu wa s ili tuweze

18
00:00:58,780 --> 00:01:03,590
iterate kutoka i hadi n,
urefu wa s, na kila

19
00:01:03,590 --> 00:01:05,760
iteration nyongeza i.

20
00:01:05,760 --> 00:01:09,970
>> Na kisha ndani ya kitanzi hii, hebu
kuangalia kwanza ni barua sasa -

21
00:01:09,970 --> 00:01:12,270
i-th barua ya s, hivyo kusema -

22
00:01:12,270 --> 00:01:14,170
lowercase barua.

23
00:01:14,170 --> 00:01:23,090
Kama s bracket i ni kubwa zaidi kuliko au sawa
kwa Herufi za chini, na ni chini ya

24
00:01:23,090 --> 00:01:26,900
kuliko au sawa na lowercase z -

25
00:01:26,900 --> 00:01:30,860
Sasa kama tunataka kubadili lowercase
barua kwa uppercase, kukumbuka kwanza kwamba

26
00:01:30,860 --> 00:01:35,810
katika ASCII lowercase a ni 97
na uppercase A ni 65.

27
00:01:35,810 --> 00:01:41,020
Wakati huo huo, lowercase b ni 98,
na uppercase B ni 66.

28
00:01:41,020 --> 00:01:44,180
>> Kama tutaendelea kuangalia mfano kwamba,
tutaweza kuona kwamba lowercase

29
00:01:44,180 --> 00:01:49,240
barua ni daima 32 maadili ya juu
kuliko herufi kubwa.

30
00:01:49,240 --> 00:01:53,490
Hivyo kama tunataka kubadili kutoka lowercase
kwa uppercase, ni lazima

31
00:01:53,490 --> 00:01:57,210
inatosha, kwa kweli, Ondoa
32 kutoka pembejeo mtumiaji.

32
00:01:57,210 --> 00:02:01,330
Au zaidi kwa ujumla, tu Ondoa kwamba
tofauti kati ya lowercase a na a

33
00:02:01,330 --> 00:02:02,310
mji mkuu wa A.

34
00:02:02,310 --> 00:02:03,410
>> Jinsi ya kueleza kwamba?

35
00:02:03,410 --> 00:02:04,640
Naam, hebu kufanya hivyo katika kanuni.

36
00:02:04,640 --> 00:02:09,960
Printf, quote, unquote "% c" kwa magazeti
tabia ya sasa, ikifuatiwa na

37
00:02:09,960 --> 00:02:18,500
uchapishaji chochote ni katika s bracket i minus
matokeo ya kufanya lowercase a

38
00:02:18,500 --> 00:02:22,660
minus uppercase semicolon.

39
00:02:22,660 --> 00:02:27,010
Kwa maneno mengine, parenthetical hii
kujieleza, kidogo minus kubwa A, ni

40
00:02:27,010 --> 00:02:29,360
kwenda na kurudi kwetu kwa njia ya
mwisho wa siku 32.

41
00:02:29,360 --> 00:02:31,230
Lakini sina kukumbuka
kwamba ni 32.

42
00:02:31,230 --> 00:02:34,150
Siwezi kuruhusu kompyuta kufikiri
nini tofauti kati ya lowercase

43
00:02:34,150 --> 00:02:35,990
a na mji mkuu wa A ni.

44
00:02:35,990 --> 00:02:39,610
>> Wakati huo huo, mara moja najua tofauti kwamba,
Naweza Ondoa kutoka s

45
00:02:39,610 --> 00:02:43,710
bracket i, ambayo itachukua nini
labda barua lowercase kwa

46
00:02:43,710 --> 00:02:48,100
thamani ya chini, yaani thamani kwamba ramani
kwenye sawa uppercase.

47
00:02:48,100 --> 00:02:51,240
Hebu sasa kuokoa, kukusanya,
na kuendesha mpango huu.

48
00:02:51,240 --> 00:02:57,760
Kufanya capitalize dot slash mtaji.

49
00:02:57,760 --> 00:03:01,290
Na pembejeo yangu itakuwa hello.

50
00:03:01,290 --> 00:03:02,920
Na huko tuna, hello.

51
00:03:02,920 --> 00:03:05,570
>> Sasa haraka yangu, admittedly, ni
kidogo mbaya, kwa sababu tumekuwa

52
00:03:05,570 --> 00:03:07,810
liliondolewa moja kidogo ya uchapishaji.

53
00:03:07,810 --> 00:03:09,370
Na hebu kwenda nyuma na kuongeza kwamba.

54
00:03:09,370 --> 00:03:12,890
Chini kabisa ya mpango huu,
Mimi nina tu sana, na kwa kiasi kikubwa kwa

55
00:03:12,890 --> 00:03:18,440
kusudi aesthetic, kwenda kuongeza printf,
quote, unquote backslash n.

56
00:03:18,440 --> 00:03:22,330
Hebu resave faili hili,
recompile, rerun.

57
00:03:22,330 --> 00:03:28,090
>> Kufanya capitalize, dot slash capitalize.

58
00:03:28,090 --> 00:03:32,540
Tena, kwa ajili ya pembejeo mimi itabidi kutoa "hello"
katika yote ya kesi ya chini na sasa hit Enter,

59
00:03:32,540 --> 00:03:34,550
na "hello," kiasi zaidi cleanly kuchapishwa.

60
00:03:34,550 --> 00:03:36,432
