C-programming basic algorithm: Exercise-21 with Solution

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

C Code:

#include <stdio.h>
#include <stdlib.h>

int main(void){
    printf("%d",test(3));
    printf("\n%d",test(7));
    printf("\n%d",test(8));
    printf("\n%d",test(21));
    }   
    
    int test(int n)
         {
            return n % 10 <= 2 || n % 10 >= 8;
         }

Sample Output:

0
