Hi, I have some questions about functions in C++. 1)I have seen functions like this:
virtual void MyFunc()=0
My question is... Why =0 ? 2) Functions like this:
void MyFunc() const
void MyFunc() 
What's the diference between both? And in wich case I should use those kind of functions.

It is a pure virtual function

That is a const member function
