Re: [Dev-C++] Derived Classes & Destructors

[Lior W. <we...@st...>]

Yes, but keep in mind, that while you only have one destructor per class,
you may have any number of constructors. So while there is no doubt as to
which destructor will be called (there is only one), it is not clear
beforehand which constructor will be used. By default, the compiler will use
the "default constructor" (big surprize!), which is the one having no
arguments. If you explicitely want to use a different constructor use the
following syntax:

class B : public A {
    public:
        B(arg1,arg2,arg3) : A(arg1,arg2+arg3) {
            // A::A(arg1,arg2+arg3) will
            // be called BEFORE this
            // constructor executes

            // B's specific stuff goes here
        };
};
