Salom dasturchi bugun siz bilan operatorslardan eng qiyini hisoblangan ++ va -- operatorlari bilan tanishamiz va yana true folse nima ekanligi va qanday ishlashini ham tushuntirib o'taman .
Operators ++ va --
++ bu songa 1 qiyat qo'shadi .
-- bu sondan 1 qiymat ayiradi.
Tushuntirish
Masalan n son bor deylik . Agar ++ ishorasi n sondan oldin kelsa u birinchi hisoblanadi . ++ n kabi . Agar ++ ishorasi n sonidan keyin kelsa u barcha amallardan keyin bajariladi . n ++ kabi
_Tushuntirish(1)_
Masalan a son bor deylik . Agar -- ishorasi a sondan oldin kelsa u birinchi hisoblanadi . -- a kabi . Agar -- ishorasi a sonidan keyin kelsa u barcha amallar bajarilgandan keyin bajariladi . n -- kabi .
ESLATMA
O'zgaruvchidan keyin kelgan ishoralar faqat qolib ketgan o'zgaruvchisi bilan qiymat o'zgartiradi .
Bu operatorslarni kod orqali tushunib olishingiz mumkin .
int main5() {
int a = 5 ;
a ++ ;
cout << ++ a << endl ; // 7
cout << a ++ << endl ; // 7
cout << a -- << " " << a ++ << endl ; // 8 //7
cout << ++ a << " " << a ++ << endl ; // 9 //9
cout << a ++ << " " << ++ a << endl ; // 10 // 12
cout << -- a << " " << a -- << endl ; // 11 // 11
cout << a ++ << " " << -- a ; // 10 // 10
// sonlari chiqadi .
return 0 ;
}
_**True va Folse**_
True va Folse - tarjimasi to'g'ri va hato
C ++ dasturlash tilida true bo'lsa ekranga 1 soni chiqadi .
Folse bo'lsa ekranga 0 soni chiqadi .
buni hozir o'zingiz ko'dda tushunib olishingiz mumkin .
// Description : Nsonini o'qing. AgarNsoni 20 va 30 orasida (20 va 30 ham kiradi) bo'lsa,1ni chop eting. Aks holda0ni chop eting.
#include <iostream>
using namespace std ;
int main() {
int n ;
cin >> n ;
cout << ((n >= 20 && n <=30 )) ;
Maqolamdan ko'p narsa bilib oldingiz degan umiddaman keyingi maqolamgacha hayr salomat bo'ling .
