C Exercises: Check if two given non-negative integers have the same last digit

C-programming basic algorithm: Exercise-13 with Solution

Write a C program to check if two given non-negative integers have the same last digit.

C Code:

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

int main(void){
    printf("%d",test(123, 456));
    printf("\n%d",test(12, 512));
    printf("\n%d",test(7, 87));
    printf("\n%d",test(12, 45));

    }       
  int test(int x, int y)
        {
          return abs(x % 10) == abs(y % 10);
        }

Sample Output:

0
1
1
0
