Cannot acces private member in friend operator.

[Guzfraba]

Hello :)
I know I failed somewhere,but I can't understand where is the mistake.Why can't i accses 'num' ?

#include <iostream>
using namespace std;


class wInt {
private:
	int num;
public:
	friend void operator+(const wInt&,const wInt&);
};



inline void operator+(const wInt& w1,const wInt w2){
	w1.num; //here
}

error at line 15,error C2248: 'wInt::num' : cannot access private member declared in class 'wInt'
Yes,i know that line 15 has no purpose,but it's enough to get the error.
Thanks in advance :)

If you want access to the private member variables you either need to make this a member function or a friend. Also you have two const parameters, what is the purpose of the function? Remember if a parameter is const you can't change that parameter.

The function is a friend,look at the declaration.This is a small part of a program,I wrote the shortest form I could,so the function has no purpose here.

inline void operator+(const wInt& w1,const wInt w2){
this should be
inline void operator+(const wInt& w1,const wInt& w2){
