Abstract: This article is a reflection on the previous post of bbs c/C ++. When I saw the post, I suddenly felt that I had timed out. It seems that I am getting unfamiliar here. This article attempts to discuss how the access control operator works,

first, the new old class of Python object-oriented 1) New Class (recommended): When defining a class, the class is followed by the base class (object) in parentheses. In python3.x, if the parent class is not specified, object is used as the base

  Given a hierarchy (inheritance system), one class student is inherited from a class person public. When it is necessary to call a function successfully, students needs to be implicitly transformed to persons, it demonstrates this to the compiler.

Example 1:----------------------------------------Class c{int C1;int C2;Publicvoid Set (c* s, int i, int j){S->C1 = i;S->C2 = j;}Friend std::ostream& operator};std::ostream& operator{osreturn OS;}C A;C b;A.set (&a, 1, 2);A.set (&b, 3, 4);coutcout3

Say in front of the point:Python clearly has a private way of defining the method is to add a double glide line in front of the variable or method, which is actually a python pseudo-private. It's just a programmer's agreement that the rules are
