I\'d like to write this code on objective c: bool BordVertical::collisionwith( Jeu& jeu, ElementJeu& element )
In a c开发者_如何学编程lass hierarchy without any virtual functions, will dynamic_cast behave as a simple static_cast since it doesn\'t have any information stored for RTTI, or it will give an error?I
In the following code, while constructing obj in case 1, we construct a derived class object too, but its member functions are just inaccessible to obj. So while downcasting (i.e., in case 2), using o
The following code throws std::bad_cast struct Foo { void foo () {} }; struct Bar { Bar () { dynamic_cast <Foo &> (*this) .foo ();
I have a problem using a shared_ptr of a base class, I can\'t seem to be able to call the derived class\'s methods when dereferencing it. I believe code will be more verbose than me:
(Please no advise that I should abstract X more and add another method to it.) In C++, when I have a variable x of type X* and I want to do something specific if it is also of type Y* (Y being a subc
For instance I have code like that class Base1 { virtual void wonderFULL() = 0; }; class Base2 { // all this weird members
I want to cast this: class Base { public: virtual ~Base(){}; }; class Der : public Base {}; int main() { const Base* bas开发者_如何学Ce = new Der;
The dynamic_cast operator is returning zero (0) when I apply to a pointer that points to an instance of a multiply inherited object.I don\'t understand why.
Here is some sample code explaining what I am trying to achieve. Basically, I have an algorithm that depends on some basic operations available in a class. I have defined those operations in a pure a
