How to define and use a friend function to a temlate class with the same template?
- by Narek
I have written the following code:
#include <iostream>
using namespace std;
template <class T>
class AA
{
T a;
public:
AA()
{
a = 7;
}
friend void print(const AA<T> & z);
};
template <class T>
void print(const AA<T> & z)
{
cout<<"Print: "<<z.a<<endl;
}
void main()
{
AA<int> a;
print<int>(a);
}
And getting the following error:
error C2248: 'AA<T>::a' : cannot access private member declared in class 'AA<T>'
1> with
1> [
1> T=int
1> ]
1> c:\users\narek\documents\visual studio 2008\projects\aaa\aaa\a.cpp(7) : see declaration of 'AA<T>::a'
1> with
1> [
1> T=int
1> ]
1> c:\users\narek\documents\visual studio 2008\projects\aaa\aaa\a.cpp(30) : see reference to function template instantiation 'void print<int>(const AA<T> &)' being compiled
1> with
1> [
1> T=int
1> ]
What's wrong?
