class Base {
    public:
    Base() {}

    void Foo(int x) {...}
};

class Derived : public Base {
    public:
    Derived(int args) {
        /* process args in some way */

        Foo(result);
    }
};

Is it allowed to call a method of the base class in the constructor of the derived class? I would imagine this is fine as the Base object should be fully constructed, but I wanted to check just in case.
