Find the maximum of three integers

Write a C program that accepts three integers and finds the maximum of three.

Pictorial Presentation:

C Code:

#include <stdio.h>
#include <stdlib.h>
int main()
{
    int x, y, z, result, max; // Declare variables
    
    // Prompt user for the first integer and store in 'x'
    printf("\nInput the first integer: "); 
    scanf("%d", &x);
    
    // Prompt user for the second integer and store in 'y'
    printf("\nInput the second integer: ");
    scanf("%d", &y);
    
    // Prompt user for the third integer and store in 'z'
    printf("\nInput the third integer: ");
    scanf("%d", &z);
    
    // Calculate the result
    result = (x + y + abs(x - y)) / 2;
    
    // Calculate the maximum value
    max = (result + z + abs(result - z)) / 2;
    
    // Print the maximum value
    printf("\nMaximum value of three integers: %d", max);
	printf("\n");
    
    return 0;
}

Sample Output:

Input the first integer: 25                                            
                                                                       
Input the second integer: 35                                           
                                                                       
Input the third integer: 15                                            
                                                                       
Maximum value of three integers: 35
