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.

C Programming: Tips of the Day
Static variable inside of a function in C
The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().
The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.
The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
