C++ Exercises: Check if a given positive number is a multiple of 3 or a multiple of 7

C++ Basic Algorithm: Exercise-10 with Solution

Write a C++ program to check if a given positive number is a multiple of 3 or a multiple of 7.

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(14) << endl;  
  cout << test(12) << endl;  
  cout << test(37) << endl;  
  return 0;    
}

Sample Output:

1
1
1
0
