00:00:00,000 --> 00:00:00,330

2
00:00:00,330 --> 00:00:02,860
>> DAVID Malan: Hebu kuandika mpango katika
PHP kwamba humshauri mtumiaji kwa

3
00:00:02,860 --> 00:00:05,350
integer na kisha huamua
kama kwamba integer ni

4
00:00:05,350 --> 00:00:07,690
chanya, 0, au hasi.

5
00:00:07,690 --> 00:00:11,480
Hapa katika hali-1.php, nimekuwa tayari
kujipatia yetu ilianza na ufunguzi na

6
00:00:11,480 --> 00:00:13,160
kufunga PHP tag.

7
00:00:13,160 --> 00:00:17,320
Hebu kwanza kutangaza variable,
tu kwa kufanya $ n.

8
00:00:17,320 --> 00:00:20,260
ishara ya dola inaonyesha kwamba hii ni
variable, na taarifa kwamba sisi si

9
00:00:20,260 --> 00:00:21,770
haja ya kutoa aina data.

10
00:00:21,770 --> 00:00:24,900
>> Hebu sasa kuwaita kazi kuitwa
readLine, ambayo ni sawa katika roho

11
00:00:24,900 --> 00:00:29,300
kwa GetString katika maktaba CS50 kwa C.
Lakini readLine pia inachukua hoja

12
00:00:29,300 --> 00:00:32,600
kwamba unasema haraka kwamba wewe d
kama kuonyesha kwa mtumiaji.

13
00:00:32,600 --> 00:00:36,660
Kwa mfano, Ningependa
integer tafadhali.

14
00:00:36,660 --> 00:00:38,910
>> Hebu sasa kuchambua pembejeo mtumiaji.

15
00:00:38,910 --> 00:00:45,860
Kama n, ni mkubwa kuliko 0, basi hebu magazeti
nje kwa printf, ilichukua

16
00:00:45,860 --> 00:00:48,880
idadi chanya.

17
00:00:48,880 --> 00:00:56,750
mwingine kama n sawa na 0, basi hebu magazeti
nje kwa printf, ilichukua 0.

18
00:00:56,750 --> 00:01:01,560
Na mwisho, mwingine kama idadi ni
labda hasi, hebu magazeti nje

19
00:01:01,560 --> 00:01:06,680
na printf, ilichukua
namba hasi.

20
00:01:06,680 --> 00:01:11,540
>> Hebu sasa ila faili hili na kupita
kwa njia ya PHP mkalimani -

21
00:01:11,540 --> 00:01:13,053
php hali-1.php.

22
00:01:13,053 --> 00:01:16,010

23
00:01:16,010 --> 00:01:17,230
Ningependa integer tafadhali.

24
00:01:17,230 --> 00:01:19,510
Vipi kuhusu 50?

25
00:01:19,510 --> 00:01:20,960
idadi chanya.

26
00:01:20,960 --> 00:01:23,195
>> Hebu kukimbia tena na, kusema, 0.

27
00:01:23,195 --> 00:01:24,500
Mimi ilichukua 0.

28
00:01:24,500 --> 00:01:27,640
Hebu kukimbia tena na,
kusema, hasi 50.

29
00:01:27,640 --> 00:01:29,430
Na mimi kweli ilichukua namba hasi.

30
00:01:29,430 --> 00:01:34,330
Lakini taarifa muhimu zaidi, tu
jinsi sawa syntax hii ni C.

31
00:01:34,330 --> 00:01:35,526
