After searching through the other threads, can't quite find my problem with linker errors. Here is a sample of a part of the code.

.cppCode:#ifndef Rectangle_h
#define Rectangle_h
#include <iostream>
using namespace std;
class Rectangle
{
public:
double avgPerimeter;
double avgArea,count; //count used a a counter to keep track of number of times i've computed the perimeter and area.
double x,y,h,w;
double Area, Perimeter;
Rectangle();
double getPerimeter();
double getArea();
friend ostream& operator<<(ostream& outputStream, Rectangle& z);
friend istream& operator>>(istream& inputStream, Rectangle& z);
private:
char color[];
};
#endif
mainCode:#include <iostream>
#include "Rectangle.h"
double getPerimeter()
{
count=count +1;
Perimeter=w+w+h+h;
avgPerimeter=(avgPerimeter+Perimeter);
return(Perimeter);
}
double getArea()
{
Area=w*h;
avgArea=(avgArea+(Area));
return(Area);
}
istream& operator >>(istream& inputStream, Rectangle& z)
{
cout << "X:";
inputStream >> z.x;
cout << "Y:";
inputStream >> z.y;
cout << "Width: ";

return inputStream;
}
ostream& operator <<(ostream& outputStream, Rectangle& z)
{
outputStream << "<rect x=\"";
outputStream << z.x;
outputStream << "\" y=\"";

outputStream << "\" Width=\"";
outputStream << z.w;

Not sure where to go from here. Should my overloaded operators be in my main?Quote:
[Linker error] undefined reference to 'operator << [std::ostream&, Rectangle&]'
