Question

I have, for example, such class:

class Base
{
   public: void SomeFunc() { std::cout << "la-la-la\n"; }
};

I derive new one from it:

class Child : public Base
{
   void SomeFunc()
   {
      // Call somehow code from base class
      std::cout << "Hello from child\n";
   }
};

And I want to see:

la-la-la
Hello from child

Can I call method from derived class?

Answer 1

Sure:

void SomeFunc()
{
  Base::SomeFunc();
  std::cout << "Hello from child\n";
}

Btw since Base::SomeFunc() is not declared virtual, Derived::SomeFunc() hides it in the base class instead of overriding it, which is surely going to cause some nasty surprises in the long run. So you may want to change your declaration to

public: virtual void SomeFunc() { ... }

This automatically makes Derived::SomeFunc() virtual as well, although you may prefer explicitly declaring it so, for the purpose of clarity.
