C Exercises: Compute the sum of three given integers. If the two values are same return the third value

C-programming basic algorithm: Exercise-29 with Solution

Write a C program to compute the sum of three given integers. If the two values are same return the third value.

C Code:

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

int main(void){    
    printf("%d",test(4, 5, 7));
    printf("\n%d",test(7, 4, 12));
    printf("\n%d",test(10, 10, 12));
    printf("\n%d",test(12, 12, 18));
    }       
    int test(int x, int y, int z)
         {
            if (x == y && y == z) return 0;
            if (x == y) return z;
            if (x == z) return y;
            if (y == z) return x;
            return x + y + z;
         }

Sample Output:

16
23
12
18

Previous: 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.
Next: Write a C program to compute the sum of the three integers. If one of the values is 13 then do not count it and its  right towards the sum.

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"
