How to find remainder of two values without using % in c++

Answer 1

Use simple math with integer division.
quotient = numerator / denominator
remainder = numerator - quotient*denominator

#include <iostream>
using namespace std;

int main() {
int numerator = 10;
int denominator = 3;
int remainder = numerator - (numerator/denominator)*denominator;
cout << remainder;
return 0;
}

Answer 2

while (dividend > divisor)
dividend -= divisor;

std::cout << "Remainder : " << dividend;

Answer 3

substract one value from another until you get a negative number
