C Exercises: Find the larger from two given integers of specified pattern

C-programming basic algorithm: Exercise-27 with Solution

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.

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, int z)
         {
             if (x == y)
            {
                return 0;
            }
            else if ((x % 5 == y % 5 && x < y) || x > y)
            {
                return x;
            }
            else
            {
                return y;
             }
         }

Sample Output:

11
20
0

Previous: Write a C program to check three given integers and return true if one of them is 20 or more less than one of the others.
Next: 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 Programming: Tips of the Day

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.

! 6.4/4 says the next preprocessing token is the longest sequence of characters that could constitute a preprocessing token"
