摘　　要：虚函数是面向对象的C++语言中的一个非常重要的概念。它充分体现了面向对象思想中的继承和多态性这两大特性,动态绑定是C++中实现多态的一个重要途径,虚函数是动态绑定的基础。通过深入分析VC++编译器实现虚函数的汇编代码。给出在继承下的实现模型,并结合实例,在汇编语言层次研究了多态性的实现机理,揭示了虚函数和动态绑定的本质。Virtual Function is an important concept of object oriented language C＋＋. It presents the Inheritance and Poly- morphism of the idea in object oriented language, dynamic binding is an important approach to realize polymorphism in C＋＋ and virtual function is its foundation, this paper investigates the realization mechanism of virtual function in assemble language in VC＋＋. Aecordi.ng to：inheritance relationship, the realize model of polymorphism is studied by example and in assemble language,and reveals the essence of virtual function and dynamic binding .
