C Exercises: Check three given integers and return true if the difference between small and medium and the difference between medium and large is same

C-programming basic algorithm: Exercise-33 with Solution

Write a C program to check three given integers (small, medium and large) and return true if the difference between small and medium and the difference between medium and large is same.

C Code:

#include <stdio.h>
#include <stdlib.h>
int main(void){    
    printf("%d",test(4, 5, 6));
    printf("\n%d",test(7, 12, 13));
    printf("\n%d",test(-1, 0, 1));
    }       
   int test(int x, int y, int z)
         {
            if (x > y && x > z && y > z) return x - y == y - z;
            if (x > y && x > z && z > y) return x - z == z - y;
            if (y > x && y > z && x > z) return y - x == x - z;
            if (y > x && y > z && z > x) return y - z == z - x;
            if (z > x && z > y && x > y) return z - x == x - y;
            return z - y == y - x;
         }

Previous: Write a C program to check two given integers and return the value whichever value is nearest to 13 without going over. Return 0 if both numbers go over.
Next: Write a C program to check a given array of integers of length 1 or more and return true if the first element and the last element are equal in the given array.
