The "pointer to member" is distinct from the type "pionter", that is, a pointer to member is declared only by the pointer to member declarator syntax, and never by the pointer declarator syntax. There is no "reference-to-member" type in c++.
pointet to member-pointer 就是指向指针成员的成员指针，不要望文生义。
n; // pointer to the int that is a member of sPointers may appear as operands to the built-in indirection operator (unary operator*), which returns the lvalue expression identifying the pointed-to object: int n; int* p = &n; // pointer to n int& r = *p; // reference is bound...

std::is_member_pointer is a UnaryTypeTrait. If T is pointer to non-static member object or a pointer to non-static member function, provides the member constant value equal true. For any other type, value is false. If the program adds specializations for std::is_member_pointer or ...

Clearly, if this extra step makes it work, one would think that with the proper syntax you should be able to just use the original value in the myFunc member without having to define "f" and reference the function through it . At any rate, if someone has some insight on what I am ...

this->member.push_back(&student); } Student& student是reference,但&student是pointer,因為&在C++同時有兩個意義,要看使用位置而定。 79行 void Lab::listAllJob() const { // POWER of Polymorphism !! // (*iter) automatically refer to derived object, ...
