I thought by definition y! = y * (y-1) * (y-2) * ... * 1

 

so the function should be:

 

int factorial(int y)
{
            if ( y =1){
                 return 1;
            }
            else
            {
                  return (y * factorial(y - 1));
             }
}

I think you mean y==1 not y=1.  I love getting that wrong.  I've had hours of fun with that type of error (in _javascript_).
IIRC, 0! = 1.  There's a reason for it somewhere.  This is satsified by the original function definition.
I think you might get infinite recursion if you try factorial(0) for a version using y==1.
