摘要： 为了提高面向对象程序中代码的复用性和效率，提出了两种在Ｃ＋＋环境中利用对象回调实现代码复用的方法，即多重继承和动态类。实践证明，这两种方法能够极大地提高代码效率。

关键词: 对象回调, 多重继承, 预处理

Abstract: In order to improve code reuse and efficiency in object oriented program, this paper presents two methods based on object callback to implement code reuse in C++ programming environment,which are multi-inheritance and dynamic class.lt's proved that they can enhance code efficiency greatly.
