The modulo operator (%) in C++ is used to find the remainder of a division operation between two integers. It is an arithmetic operator that returns the remainder when one integer is divided by another1.
Example
#include <iostream>using namespace std;int main() {int x = 10;int y = 3;int result = x % y;cout << "10 % 3 = " << result << endl; // Output: 1return 0;}Restrictions
The modulo operator cannot be applied to floating-point numbers (i.e., float or double). Attempting to use it with floating-point constants or variables will result in a compilation error1.
#include <iostream>using namespace std;int main() {float x = 2.3;float y = 1.5;// int result = x % y; // Compilation errorreturn 0;}Negative Operands
The sign of the result for the modulo operator is machine-dependent for negative operands1.
#include <iostream>using namespace std;int main() {int x = -10;int y = 3;int result = x % y;cout << "-10 % 3 = " << result << endl; // Output: -1 (compiler dependent)return 0;} c++ - How does the % operator (modulo, remainder) work?
