Today in a C code to see a function of the formal parameter is (int *&a) actually is this thing, which makes me very puzzled ah, do not know with so many address symbols what is the purpose? The address?That's not necessary, just need to use a

Smart pointer (smart pointer) is a class that stores pointers to dynamically allocated (heap) objects and is used for lifetime control to ensure that dynamically allocated objects are destroyed automatically and correctly to prevent memory leaks.

When a function is not part of a specific instance and belongs to the entire class, then this function is best written as a static member function, so that it can be called directly with the class nameClass::func ()For general member functions when

override ( occurs in subclasses and parent classes ):Virtual functions allow subclasses to redefine member functions, and subclasses that redefine the parent class are called overrides (override), or are called overrides.There are two types of

From a compilation standpoint, a declaration simply tells the compiler that a variable of a certain type will be used, but the compiler will not allocate any memory for it. And the definition is allocating memory.int A; On the outside is as a

An abstract function has to be overridden while a virtual function may be overridden. Virtual functions can have a default/generic implementation in the base class. An abstract function can have no functionality. you're basically saying, any child
