1
00:00:00,320 --> 00:00:03,740
Komputerlarning yaxshi jihatlaridan biri bu buyruqlarni qayta bajarishi.

2
00:00:03,740 --> 00:00:08,170
Inson sifatida, agar siz bir xil narsani ko‘p marta qilishingiz kerak bo‘lsa, 

3
00:00:08,170 --> 00:00:08,809
haqiqatda zerikib ketasiz.

4
00:00:08,809 --> 00:00:12,849
Ammo komputer bir xil narsani million yoki hattoki
milliard marta ham qila oladi, 

5
00:00:12,849 --> 00:00:15,000
va zerikmasdan yaxshi holatda bu ishni oxirigacha yetkazib qo‘ya oladi.

6
00:00:15,500 --> 00:00:17,430
Shunday qilib, misol uchun, agar men <i>Facebook</i>dagi barcha foydalanuvchini 

7
00:00:17,430 --> 00:00:20,960
<i>email</i> jo‘natib tug‘ilgan kuni bilan tabriklashni xohlasam, 

8
00:00:20,960 --> 00:00:24,850
bu <i>email</i>larni barchaga yozib jo‘natish uchun 

9
00:00:24,850 --> 00:00:25,269
menda bir asrdan ko‘p vaqt ketadi.

10
00:00:25,269 --> 00:00:28,760
Lekin bir necha qator kod bilan, men <i>Facebook</i>dagi 
barchaga tug‘ilgan  

11
00:00:28,760 --> 00:00:32,229
kuni bilan tabriklab <i>email</i> yuboradigan
tizim yarata olaman.

12
00:00:32,229 --> 00:00:34,000
Mana <i>loop</i> - sikllar nima va nima uchun ular ahamiyatli.

13
00:00:34,500 --> 00:00:37,180
Ular kompyuterlar juda yaxshi bajara oladigan narsalardan biri.

14
00:00:37,180 --> 00:00:40,550
Bu misolda, sizning maqsadingiz qushni cho‘chqaga yetishi 

15
00:00:40,550 --> 00:00:44,940
uchun harakatlantirish. Biz buni juda ham oson bajarish uchun

16
00:00:44,940 --> 00:00:49,210
"<i>repeat</i>" blokidan foydalana olish imkoniyatiga egamiz. Siz buni 

17
00:00:49,210 --> 00:00:52,219
har safar qushni cho‘chqaga qaratib bir qadam yaqinlashtirish uchun 

18
00:00:52,219 --> 00:00:57,079
komputerga besh marta "<i>move forward</i>" buyug‘ini berish orqali ham bajarishingiz mumkin.

19
00:00:57,079 --> 00:01:00,590
Yoki siz komputerga shunchaki bir marta oldinga harakatlanishini aytib, 

20
00:01:00,590 --> 00:01:04,150
va keyin unga bu ishni 5 marta qaytarishni aytishingiz mumkin
va u xuddi shunday qiladi.

21
00:01:04,150 --> 00:01:08,280
Shunday qilib, buni qilish uchun siz "<i>move forward</i>" buyrug‘ini olib, 

22
00:01:08,280 --> 00:01:11,729
uni "<i>repeat</i>" bloki ichiga joylaysiz.

23
00:01:11,729 --> 00:01:16,200
Bu yerga bosib, qancha qadam oldinlashini xohlashingizni

24
00:01:16,200 --> 00:01:19,970
aytish uchun blokni necha marta qaytarishini ayta olasiz.
Endi yana bir narsa 

25
00:01:19,970 --> 00:01:23,540
siz <i>repaat </i> bloki ichiga 
istalgancha ko‘p buyruqlarni qo‘ya olasiz.

26
00:01:23,540 --> 00:01:26,909
Masalan, bu yerda siz unga besh marta 

27
00:01:26,909 --> 00:01:30,970
oldinga harakatlanish va chapga burilishni aytayapsiz.
Xo‘sh... 

28
00:01:30,970 --> 00:01:31,220
Ajoyib! Zavq oling :-)
