The implementation of the 1.c++ virtual function is to arrange a vptr for class to point to an array. The first item of an array is usually saved type_info. The other items are virtual function addresses. There may also be pointers to virtual base

The actual project often encountered many similar operations, such as command code corresponding to the execution function, for such operations, the better way is to use the const array, the command code and operation functions are bound together,

A pointer is a special variable, and the value stored in it is interpreted as an address in memory. To make sense of a pointer, you need to be aware of the four aspects of the pointer: the type of pointer, the type that the pointer points to, the
