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

Previous: Write a C++ program to create a new string with the last char added at the front and back of a given string of length 1 or more.
Next: Write a C++ program to create a new string taking the first 3 characters of a given string and return the string with the 3 characters added at both the front and back. If the given string length is less than 3, use whatever characters are there.
