At the beginning of chapter 9 "high quality programming guide _ Lin Rui,   "The default copy constructor and the default value assignment function are both implemented by 'bit copy' instead of 'value copy'. If the class contains pointer variables,

Typedef int (* healthcalcfunc) (const gamecharacter &)   When a member function is declared as a virtual function, all functions of the same name in the derived class automatically become virtual functions. Therefore, when the subclass declares the

For those who have learned C ++, the keyword "virtual" is no stranger, because it is a tool in the program and can help us achieve dynamic Association. Next we will take a closer look at this keyword.First, we need to ask why the keyword "virtual"

Before getting started with c ++ template programming, I really didn't think that c ++ could be used like this. The biggest feeling is that it is too flexible and powerful. The initial launch of the template was still in Delta3d. I felt that the
