C + + Primer Plus Study: Tenth chapter

Procedural programming and object-oriented programming

Object-oriented Programming (OOP) Features:

• Abstract
• Encapsulation and data hiding
• Polymorphic
• Inherited
• Reusability of code

Abstractions and classes

A class is a C + + tool that translates abstractions into user-defined types, which synthesize a concise package of data representation and manipulation of data.

Constructors and destructors for classes

Constructor: Same as class name

Destructor: ~ Class name

Object Initialization method:

ClassName Cn=classname (...); or classname cn (...);

If the member function of a class does not modify the calling object, it should be identified as a const type, such as: Void Show () const;

This pointer

The this pointer points to the calling object of the class. *this represents an object.

Class scope

The names defined in the class are scoped to the entire class.

A constant scoped to a class

Enum{k=19};int A[k]; static cons tint k=19;

Abstract data type
