Sum of Two Numbers Modulo M in C++

In this problem, we are given three numbers a, b, and M. our task is to create a program to find the sum of two numbers modulo M.

Let’s take an example to understand the problem,

Input: a = 14 , b = 54, m = 7
Output: 5
Explanation: 14 + 54 = 68, 68 % 7 = 5

To solve this problem, we will simply add the numbers a and b. And then print the remainder of the sum when divided by M.

Example

Program to illustrate the working of our solution,

 Live Demo

#include <iostream>
using namespace std;
int moduloSum(int a, int b, int M) {
   return (a + b) % M;
}
int main() {
   int a = 35, b = 12, M = 7;
   cout<<"The sum modulo is "<<moduloSum(a,b,M);
   return 0;
}

Output

The sum modulo is 5
