C++ da operatorlar

• Increment/Decrement operatorlar "++" va "--" operatorlari o'zgaruvchidagi qiymatni bittaga oshiradi yoki kamaytiradi.

#include <iostream>
#include <iomanip>

using namespace std;
int main() {
  int n = 5;
  ++n;

  cout << n;

  return 0;
}

Agar kadimizda Increment/decrement o'zgaruvchidan oldin kelsa birinchi bo'lib Increment/decrement hisoblanib keyin boshqa buyruqlar bajariladi:

#include <iostream>
#include <iomanip>

using namespace std;
int main() {
  int n = 5;

  cout << ++n << endl;
  cout << n;

  return 0;
}
