C Exercises: Accept two integers and return true if either one is 5 or their sum or difference is 5

C-programming basic algorithm: Exercise-18 with Solution

Write a C program that accept two integers and return true if either one is 5 or their sum or difference is 5.

C Code:

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

int main(void){
    printf("%d",test(5, 4));
    printf("\n%d",test(4, 3));
    printf("\n%d",test(1, 4));
    }   
    
    int test(int x, int y)
         {
          return x == 5 || y == 5 || x + y == 5 || abs(x - y) == 5;
        }

Sample Output:

1
0
1

Why doesn't a+++++b work?

printf("%d",a+++++b); is interpreted as (a++)++ + b according to the Maximal Munch Rule!.

++ (postfix) doesn't evaluate to an lvalue but it requires its operand to be an lvalue.
