I am a new C++ programmer using Turbo C++ on the PC. Basically, my
problem is this: I would like to be able to access the private members
of class X from class Y i.e. class Y is to be a friend of class X.
I have consulted p113 of the Turbo C++ programmers guide which suggests
something along the following lines...
----------------------------------------
#include <iostream.h>
class X
{
friend class Y; // Make the private members i, j accessible to
int i; // class Y ????
int j;
public:
X(){i = 1; j = 2;}; // Constructor for class X
};
class Y
{
public:
friend void getXij(X& x){cout << "x.i = " << x.i << "\n";
cout << "x.j = " << x.j << "\n";}; // Accesses i, j ?!
};
int main()
{
X x;
getXij(x);
return 0;
}
------------------------------------------
However, when I try to compile the above segment I get the following errors
Error: X::i is not accessible in function getXij;
Error: X::j is not accessible in function getXij.
I would be very grateful if someone could shed some light on this problem.
Response via Email would be appreciated. Many thanks in advance...
