C++ Exercises: Check if a given non-negative number is a multiple of 3 or 7, but not both

C++ Basic Algorithm: Exercise-40 with Solution

Write a C++ program to check if a given non-negative number is a multiple of 3 or 7, but not both.

Sample Solution:

C++ Code :

#include <iostream>
 
using namespace std;

bool test(int n)
        {
            return n % 3 == 0 ^ n % 7 == 0;
        }
     
        
int main() 
 {
  cout << test(3) << endl; 
  cout << test(7) << endl; 
  cout << test(21) << endl;         
  return 0;      
}

Sample Output:
