Visibility of Class Variables

I did not check it in the C++ standard, but as I understand it, variables, typedefs and functions are not only visible from the point of declaration, but within the entire class. So the following will compile:

class A {

public:

  A() {

    private_type var;

    private_variable = 5;

    private_function();

  }
private:

  typedef int private_type;

  int private_variable;

  void private_function();

};

Don’t use a private typedef within the parameter declaration of a public class, though. It may work, but it shouldn’t since whoever uses that function should also have the types of the parameters available.
