How to determine if there is a remainder of a division in c++?

how to do it?

Answer 1

const int a=5%2; //% - вычислить остаток от деления левого на правое
cout<<a;

In C++, the remainder of a division is determined by the % operator. For example:
int a = 5 % 3;

Answer 4

There is also a function that will return both the integer part and the remainder of the division. If both components are required, then it is better to use it.

#include <cstdlib>

div_t res = div(5,3);
// res.quot 1 -- целая часть
// res.rem 2 -- остаток
