This article mainly explains "what are the basic polymorphisms of C++", interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn what are the basic polymorphisms of C++.

C++ is divided into compile-time polymorphism and run-time polymorphism according to the timing of implementation.

1. Compile-time polymorphism also becomes static linkage, which means that the program determines the polymorphism at the time of compilation and is realized through the overloading mechanism.

2 Runtime polymorphism, also known as dynamic binding, refers to the polymorphism that can only be determined in operation, which is realized by inheritance and virtual functions.

If the same function as the base class is defined in the derived class, when the base class pointer is used to point to the derived class object, the function of the base class is called through the pointer rather than the function in the derived class.
