Komputerlarning yaxshi jihatlaridan biri bu buyruqlarni qayta bajarishi.

0:00:03.740,0:00:08.170
Inson sifatida, agar siz bir xil narsani ko‘p marta qilishingiz kerak bo‘lsa, [br]haqiqatda zerikib ketasiz.

0:00:08.170,0:00:08.809


0:00:08.809,0:00:12.849
Ammo komputer bir xil narsani million yoki hattoki[br]milliard marta ham qila oladi,

0:00:12.849,0:00:15.000
va zerikmasdan yaxshi holatda bu narsani oxirigacha yetkazib qo‘ya oladi.

0:00:15.500,0:00:17.430
Shunday qilib, misol uchun, agar men <i>Facebook</i>dagi barchani

0:00:17.430,0:00:20.960
<i>email</i> jo‘natib tug‘ilgan kuni bilan tabriklashni xohlasam,

0:00:20.960,0:00:24.850
bu <i>email</i>larni barchaga yozib chiqish uchun menga bir asrdan ko‘p vaqt[br]ketadi.

0:00:24.850,0:00:25.269


0:00:25.269,0:00:28.760
Lekin bir necha qator kod bilan, men <i>Facebook</i>dagi [br]barchaga tug‘ilgan

0:00:28.760,0:00:32.229
kuni bilan tabriklab <i>email</i> yuboradigan[br]sistema tuza olaman.

0:00:32.229,0:00:34.000
Mana <i>loop</i>lar nima, va nima uchun ular qiymatli

0:00:34.500,0:00:37.180
va ular komputerlar juda yaxshi bajara oladigan jihatidan biri.

0:00:37.180,0:00:40.550
Bu misolda, sizning maqsadingiz qushni cho‘chqaga yetishishi

0:00:40.550,0:00:44.940
uchun harakatlantirish. Hozir, biz buni juda ham oson bajarish uchun

0:00:44.940,0:00:49.210
"<i>repeat</i>" bo‘limidan foydalana olish imkoniyatiga egamiz. Yoki siz buni

0:00:49.210,0:00:52.219
har safar qushni cho‘chqaga nisbatan bir qadam oldinga chiqarish maqsadida

0:00:52.219,0:00:57.079
komputerga besh marta "<i>move forward</i>" buyug‘ini berish orqali ham bajarishingiz mumkin.

0:00:57.079,0:01:00.590
Yoki siz komputerga shunchaki bir marta oldinga harakatlanishini ayta olasiz,

0:01:00.590,0:01:04.150
va keyin unga bu jarayonni 5 marta qaytarishni aytishingiz mumkin[br]va u xuddi shunday qiladi.

0:01:04.150,0:01:08.280
Shunday qilib, buni qilish uchun siz "<i>move forward</i>" buyrug‘ini [br]olib keling,

0:01:08.280,0:01:11.729
va keyin uni "<i>repeat</i>" bo‘lim ichiga qo‘ying.

0:01:11.729,0:01:16.200
Va siz uning ustiga bosa olasiz va unga qancha qadam oldinlashini xohlashingizni

0:01:16.200,0:01:19.970
aytish uchun bo‘limni necha marta qaytarishini ayting.[br]Endi yana bir narsa bu

0:01:19.970,0:01:23.540
siz <i>repaat </i> bo‘limi ichidagidek [br]ko‘p buyruqlarni qo‘ya olasiz.

0:01:23.540,0:01:26.909
Demak, bu misolda siz unga besh marta bajarilishi kerak bo‘lgan

0:01:26.909,0:01:30.970
oldinga harakatlanishni va chapga burilishni aytayapsiz.[br]Juda yaxshi ish, rohatlaning:-)
