Hello all. I am new to the board and hope to build great relationships with other forum members. I am working on a program for class that is supposed to show the GCD. I used a text editor to make it, but when i put it in Visual express 2008, it keeps showing error messages, when I thought I did it properly. Can anyone show me what I did wrong so I can make it work in visual? Thank you very much

#include "stdafx.h"

int main()
{
Declare x, y, temp, remainder as Integer.
int x;
int y;
int temp
int remainder = 1;
// read in the two integers
cout << endl ;
cout << "Enter the first number (positive integer) : " ;
cin >> x ;
cout << "Enter the second number (positive integer) : " ;
cin >> y ;
//echo inputs
cout << "Input numbers are: " << x << " , " << y << endl ;
Write a C++ if statement to determine if x < y.
if ((x == 0) || (y == 0))
{
cout << "ERROR: Value of 0 has been entered."
return (-1);
}
if (x < y)
{ // exchange values of x and y
temp = x;
x = y;
y = temp;
}
/* At this point we will always have x >= y */
Initialize remainder.
while ( remainder != 0 )
{
Write the loop expression and loop body code in C++.
In C++, the expression (x % y) gives the remainder
after dividing x by y.
// value of q
temp = x / y;
// value of r
remainder = x % y;
// replace x with y
x = y;
// replace y with remainder
y = remainder;
}
// display the result
cout << endl ;
cout << "The GCD is: " << y << endl ;
return (0); // terminate with success
}
