C＋＋函数重载机制及其实现

OVER-LOAD FUNCTION OF C++ AND ITS IMPLEMENTATION

多态性是面向对象程序设计的重要支柱之一．函数重载机制在Ｃ＋＋中用来支持多态性．本文针对Ｃ＋＋中函数重载机制实现中的主要问题提出了重载函数链表、函数类型匹配和系统换名等技术，完成Ｃ＋＋编译系统中函数重载的实现．

Polymorphism is an important feature of object-oriented languages.Over-load function is one of facilities to support polymorphism in C+ +. In this paper, the technology of constructing over-load function link table,matching functiontype and renaming function are proposed. The algorithm to implement over-loadfunction in C++ compiler system is also introduced.
