computing the GCD non-recursively

Hello,

I am working on this program that needs to compute the GCD non-recursively the programs has no errors but when it says result is not initlized because of this it aborts.

#include "stdafx.h"
#include "stdio.h"

int main (void)
{
int a,b,c,r,result;
printf("enter a value for a\n");
scanf ("%d", &a);
printf("enter a value for b\n");
scanf ("%d", &b);
printf("The result is %d\n",result);
{

if (a < b)
c = a;
a = b;
b = c;
return 0;
}

while(1)
int c;
{
c = a%b;
if(c==0)
return b;
a = b;
b = c;
}
}

Well, it's not. Nowhere do you assign anything to result, so who knows what it is. Also, maybe you want to do the calculations before you do the printing. It looks like you're missing the line

Code:

---

result = function_name(a, b)

---

and the thing at the bottom is supposed to be a function and not inside main.
