A simple question of a C++ function

meili100 · #1 07-May-2007, 18:00

Here is a class

CPP / C++ / C Code:

class Complex{
private:
	int real, image;
public:
	Complex(int r=0, int i=0):real(r),image(i){}

	int GetReal() {return real;}
	int GetImage() {return image;}

	void foo(const Complex & rhs){
		cout<<rhs.image<<endl;
		return;
	}
};

It works, but my question is that 'image' is private of 'rhs', how can you visit a private variable of rhs outside (rhs.image)?

The function foo that is being defined here is a member function of the class (since it is inside the class Complex {}; braces), so it has access to all class members.

If "outside" functions want to print the value of the image member, they can use the foo function. If "outside" functions want to get the value of the image member, thay can use the GetImage function.

Dave
