C Exercises: Check two given integers, each in the range 10..99. Return true if a digit appears in both numbers, such as the 3 in 13 and 33

C-programming basic algorithm: Exercise-28 with Solution

Write a C program to check two given integers, each in the range 10..99. Return true if a digit appears in both numbers, such as the 3 in 13 and 33.

C Code:

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

int main(void){    
    printf("%d",test(11, 21));
    printf("\n%d",test(11, 20));
    printf("\n%d",test(10, 10));
    }       
    int test(int x, int y)
         {
            return x / 10 == y / 10 || x / 10 == y % 10 || x % 10 == y / 10 || x % 10 == y % 10;
         }

Sample Output:

Previous: Write a C program to find the larger from two given integers. However if the two integers have the same remainder when divided by 5, then the return the smaller integer. If the two integers are the same, return 0.
Next: Write a C program to compute the sum of three given integers. If the two values are same return the third value.
