Methods not accessible by other classes

[Zool]

I have created a class "map" that can load a file from a special format but which can save data in a file format. There is also a class "Game" and a class "Publisher". Is it possible to ensure that the class never use the recording method and inverse method for the Publisher? Thank you for your answers.

Normally when you want to call method of any other class we need to create its object then we can access its methods. Namespaces allow to group entities like classes, objects and functions under a name. This way the global scope can be divided in "sub-scopes", each one with its own name.

Check this Example :

namespace Box1{
  int boxSide = 4;


}

namespace Box2{
  int boxHeight = 12; 


}

int main () {
 cout << Box1::boxSide << endl;    //output 4
 cout << Box2::boxHeight << endl;  //output 12
 return 0;


}

You can only assure that nobody will use these methods to the class one and another class putting them in private, but if you give them access to a method, you necessarily give them access to those same accessibility (public, private or protected).
