C++ equivalent of super(...)
Author
Is there anything in C++ that one can use to call the constructor of a parent class from within the constructor of a child class? This is similar to Java''s super(...), if anyone is familiar with that.
Yes, you can do the following:
Derived::Derived()
{
Base::Base();
}
In this case Derived inherits from Base.
Derived::Derived()
{
Base::Base();
}
In this case Derived inherits from Base.
class Baseclass{public: Baseclass();};class Derived : public Baseclass{ public: Derived();};// either do this:Derived::Derived() : Baseclass(){ };// or do this:Derived::Derived(){ ::Baseclass(); // or even Baseclass::Baseclass(); // or even this works i think: Baseclass();}; I have spoken.
The constructor of the base class will be called before the constroctor of the derived class. You don''t need to do this yourself.

Yeah, my problem was that I wanted to extend ifstream and ofstream so that the write and read commands could accept any type of data, rather than just char*. So, being able to call the non-default constructor is rather important... It''s working well now though, so thanks!
