摘要: 2011-09-18今天补习C++virtual函数和纯virtual函数(pure vitural function),可以使一个类成为抽象类。一个纯virtural函数是在声明时“初始化值为0”的函数,如下所示:virtual void f() const = 0;//pure virtual function“=0”成为纯指示符(pure specifier)。纯virtual函数不提供函数的具体实现,每个派生的具体类必须重写所有基类的纯virtual函数的实现,并且提供派生类是否重写这些函数的选择权。相反,纯virtual函数并不提供函数的实现,需要派生类重写这些函数以使派生类成为具体 阅读全文
