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 the same.

C Code:

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

// Function prototype for 'test'
int test(int x, int y, int z);

int main(void) {
    // Printing the results of calling 'test' function with different arguments
    printf("%d", test(4, 5, 6));
    printf("\n%d", test(7, 12, 13));
    printf("\n%d", test(-1, 0, 1));
}

// Definition of the 'test' function
int test(int x, int y, int z) {
    // Checking various conditions and returning the result of the comparisons
    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;

    // If none of the above conditions are met, return the result of the final comparison
    return z - y == y - x;
}

Sample Output:

1
0
1

C Programming Code Editor:

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.
