This is another GCD program. Everything is working correctly besides validating the inputs correctly.

My goal:

Here's the code:Provide a function to get a nonzero positive integer from the keyboard and return it to the caller.

int get_input()

If input is not valid, the function should output an error message and repeat the input operation.

Be sure your input function works correctly with invalid inputs.

Even inputs that are not integers

123.456 (Should return 123)

abc (Should output error message and repeat input.)

I don't think I have it validating my inputs correctly. Also, the error message doesn't show if I input zero. For example,Code:#include <stdio.h> int gcd(int x, int y); int gcd(int x, int y) { if (y == 0) return x; else return gcd(y, x % y); } int get_input(int x, int y) { while(1) { if (x > 0 || y > 0) { return 1; } else { printf("Input error"); printf("Please enter an integer greater than 0"); while(getchar() != '\n'); //Clears input buffer } } } int main() { int x, y, input, common; printf("This program computes the greatest common divisor\n"); printf("of positive integers X and Y, entered by the user.\n"); printf("Inputs must be integers greater than zero.\n\n"); printf("Enter integer X: \n"); scanf("%d", &x); printf("Enter integer Y: \n"); scanf("%d", &y); input = get_input(x,y); common = gcd(x, y); printf("The GCD of %d and %d is %d\n", x, y, common); return 0; }

Enter integer X:

123.123

Enter integer Y:

The GCD of 123 and 4 is 1

It skips Y automatically and it shouldn't according to the sample output I have. I'm not sure how to fix this. Also, when I enter "abc" it just doesn't work as the sample output. Here's the sample out put.

I appreciate it if someone can give me tips on how to go on doing this. Thanks.Enter integer X: 0

Please enter an integer greater than 0

123.456

Enter integer Y: Please enter an integer greater than 0

abc

Please enter an integer greater than 0

44

The GCD of 123 and 44 is 1
