The "C + +" this pointer

From: Huang Bongyong Handsome

The this pointer is an implicit pointer to all member functions, and each time the member function is called, the this pointer points to the object that called the function. You can use the this pointer explicitly in the member function Class section.

A friend function is not a member function of a class, so the friend function does not have the this pointer. The static member function also does not have the this pointer.

The this pointer defaults to the * const this type, that is, this is a constant pointer and cannot change the address that the this pointer points to.
