Article Introduction：In C++, pure virtual functions are declared but not implemented in the base class, forcing derived classes to implement specific behavior to promote polymorphism. Derived classes must implement all pure virtual functions, otherwise they must also become abstract classes. Pure virtual functions ensure polymorphism by ensuring that only classes that implement all pure virtual functions can be used as pointers or references to abstract classes. In practical cases such as graphics drawing, it can ensure that all shape objects can respond to draw() calls, achieve polymorphism, and improve the scalability and maintainability of the code.
