C++ Exercises: Check if a given number is within 2 of a multiple of 10

C++ Basic Algorithm: Exercise-41 with Solution

Write a C++ program to check if a given number is within 2 of a multiple of 10.

Sample Solution:

C++ Code :

#include <iostream>
 
using namespace std;

bool test(int n)
        {
             return n % 10 <= 2 || n % 10 >= 8;
        }
     
        
int main() 
 {
  cout << test(3) << endl; 
  cout << test(7) << endl; 
  cout << test(8) << endl;
  cout << test(21) << endl;         
  return 0;      
}

Sample Output:

0
0
1
1

Previous: Write a C++ program to check if a given non-negative given number is a multiple of 3 or 7, but not both.
Next: Write a C++ program to compute the sum of the two given integers. If one of the given integer value is in the range 10..20 inclusive return 18.
