[問題] 怎麼樣把單一的class member function弄成別人的friend?

[popo4231 (小泰)]

is this ok?
class A
{
public:
void x()
{
}

};
class B
{
friend void A::x();
}

推 ric2k1:Yes, friendship is granted, not taken.
→ ric2k1:so you are correct. Now A::x() can access B's private
推 ric2k1:data members and member functions.
→ ric2k1:We will cover this in next lecture too.
