Question

There is something bugging me about classes. For example

{
public:
  A()
  {
  .....
  .....
  }

  void cleanup()
  {
  ....
  ....
  ....
  }

publ         


        

Answer 1

The class is correct, public is just a access qualifier and will apply till the next qualifier is seen or the end of class declaration. There is no limit to how many of these access qualifiers(public, private, protected) you can have in a class. As to why this is useful, it helps writing class declarations the way you want. For example I might want all the member functions (public,protected or private) declared before the (say) private data members.
