Virtual functions are normal member functions of a class, which can be over-ridden in the derived classes. The whole functionality can be replaced in the over-riding function. In C#, the virtual functions will be declared with a keyword 'virtual' and the over-riding functions will be ...

This is perhaps the biggest benefit of virtual functions -- the ability to structure your code in such a way that newly derived classes will automatically work with the old code without modification! A word of warning: the signature of the derived class function must exactly match the signature...

static, const, inline, virtual function 辨析 static 是c++中很常用的修饰符,它被用来控制变量的存储方式和可见性,下面我将从 static 修饰符的产生原因、作用谈起,全面分析static 修饰符的实质。 static 的两大作用: 一、控制存储方式: static被引入以告知编译器,将变量存储在程序的静态存储区而非栈上空间。

function whose address is at offset 8 in the vtable. (Each pointer is 4 bytes, so the third pointer, func3, is at offset 8.) This is what makes virtual functions virtual: the call is indirect. C++ jocks say the function is bound at runtime, or late-bound (as a opposed to compile...
