Problem with this programming I'm making!

Okay, I've looked over my thing like a million times and I can't figure out whats wrong! (Yea I'm pretty new at programming...)

Here's the code I'm working with...any help would be greatly appreciated! Thanks!

RECT.HPP

//Begin Rect.hpp
#include <iostream>

class Point //holds x,y coordinates
{
//no constructor, use default
public:
void SetX(int x) {itsX = x;}
void SetY(int y) {itsY = y;}
int GetX()const {return itsX;}
int GetY()const {return itsY;}
private:
int itsX;
int itsY;
}; //end of Point class declaration

class Rectangle
{
public:
Rectangle(int top, int left, int bottom, int right);
~Rectangle(){}

int GetTop() const {return itsTop;}
int GetLeft() const {return itsLeft;}
int GetBottom() const {return itsBottom;}
int GetRight() const {return itsRight;}

Point GetUpperLeft() const {return itsUpperLeft;}
Point GetLowerLeft() const {return itsLowerLeft;}
Point GetUpperRight() const {return itsUpperRight;}
Point GetLowerRight() const {return itsLowerRight;}

void SetUpperLeft(Point Location);
void SetLowerLeft(Point Location);
void SetUpperRight(Point Location);
void SetLowerRight(Point Location);

void SetTop(int top);
void SetLeft(int left);
void SetBottom(int bottom);
void SetRight(int right);

int GetArea() const;

private:
Point itsUpperLeft;
Point itsLowerLeft;
Point itsUpperRight;
Point itsLowerRight;
int itsTop;
int itsLeft;
int itsBottom;
int itsRight;
};
//end Rect.hpp

RECT.CPP

//Begin rect.cpp
#include "Rect.hpp"

Rectangle::Rectangle(int top, int left, int bottom, int right)
{
itsTop = top;
itsLeft = left;
itsBottom = bottom;
itsRight = right;

itsUpperLeft.SetX(left);

}

}

void Rectangle::SetBottom(int bottom)
{

itsLowerRight.SetY(bottom);
}

void Rectangle::SetRight(int right)
{
itsRight = right;
itsUpperRight.SetX(right);
itsLowerRight.SetX(right);
}

int Rectangle::GetArea() const
{
int Width = itsRight-itsLeft;
int Height = itsTop - itsBottom;
return(Width*Height);
}

//compute are of the rectangle by finding corners,
//establishing width and height and then multiply
int main()
{
//initialize a locatl Rectangle variable
Rectangle MyRectangle(100, 20, 50, 80);

int Area = MyRectangle.GetArea();

std::cout << "Area: " << Area << "\n";
std::cout << "Upper Left X Coordinate: ";
std::cout << MyRectangle.GetUpperLeft().GetX();
system("pause");
return 0;
}

Hmm, I've tried your example and it workd for me, so you have these options:

You have to havefollowing files: rect.hpp, rect.cpp, test.cpp

test.cpp
___________________
#include <rect.h>

int main(int argc, char *argv[])
{
...
}
_____________________


rect.hpp
___________________
#ifndef RECT_HPP
#define RECT_HPP

.. your stuff ..

#endif
___________________


rect.cpp
__________________
#include <rect.hpp>

.. your stuff ..
__________________

Now try woth these 3 files and it should work. If it doesn't, problem is in you compiler so change it
Since I use Linux, I tried this with Intel & gcc compilers, and it works flawlessly.
