WitrynaC++中的动态多态是通过虚函数（virtual function）实现的。 其基本使用是：在父类中定义一个虚函数，在子类中重写这个虚函数。 在程序运行时，通过基类指针或引用指向子类对象，并使用基类对象调用虚函数时，会自动调用子类的重写版本。 Witryna13 kwi 2024 · Coroutines in С++ 20. Similarly to Rust, in C++, programmers initially had to use complex mechanisms — callbacks and lambda expressions — when they wanted to write event-driven (asynchronous) code.
