B、Friend functions access object members by “this” pointer. C、A friend of a class can directly access the public and protected members of the class, but cannot directly access a private member D、Friend function of a class can access the private members of the class, but it destroys th...
The following code now produces C2248: 'S::S': cannot access private member declared in class 'S': C++ Copy class S { S(); public: int i; }; class S2 { auto f() -> decltype(S().i); }; To fix the error, add a friend declaration for S2 in S: C++ Copy class S {...
