I\'m making a base class for my container classes to derive from so I can maintain a consistent interface.It currently looks something like this:
I want to define an abstract base class with a vector of struct variables, and a virtual function to be implemented by deri开发者_如何学编程ved classes:
Assume the following simple case (notice the location of virtual) class A { virtual void func(); }; class B : public A {
Imagine I have a class called Engine as an abstract base class. I also have ElectrictEngine and FuelEngine classes which derive from it.
I am passing a pure-virtual base class pointer arround through C code as a void *. When I dereference the base class in C++, the debugger is able to access all of its members. However, when I attempt
Conside开发者_运维技巧r a scenario where there are two classes i.e. Base and Derived. If the Base class wants to call a function of the derived class, it can do so by either making a virtual function
How are virtual functions implemented in position-independent code? I know that if my class has virtual functions, the compiler usually generates a vtable for it that contains addresses of all virtua
#include <iostream> class base { public: virtual void print (int a) { std::cout << \"a: \" << a << \" base\\n\";
This question already has answers here: Closed 11 years ago. Possible Duplicate: C++: why is new needed?
Why do I sometimes see in C++ examples when talking about subclassing / inheritance, the base class has virtual keyword and sometimes the over开发者_如何转开发ridden function has also the virtual keyw
