First, the meaning of object-oriented programming * is a modular programming method, so that the reuse of code greatly increased. * OOP technology makes the design phase of a project much more energetic, but once a certain type of data expression is agreed upon, this expression can be used until the end of the life cycle of the application.

Each class member function involves only one object, that is, the object that invokes it. However, sometimes a method might involve two objects, in which case you need to use the this pointer of C + +Assuming that the method is named Topval (), the function call Stock1.topval () accesses the Stock1 object data; Stock2.
Three main features of object-oriented:1. Inheritance 2. Package 3. Polymorphic1> inheriting a Face object allows an object of one type to obtain the properties and methods of another object.2> encapsulates data and code in an object

We all know that C is a process-oriented language, how to simulate object-oriented?Do not forget the structure of this thing, said and the class is still somewhat similarFirst we have to understand what is called a linked list, just like a line of people lined up one after another, you find the first one to know the ne

1. The core idea of object-oriented program design is data abstraction, dynamic binding and inheritance.Inheritance: roots are called base classes, and inherited classes are called derived classes. A derived class must explicitly indicate which base class it inherits from by using a list of derived classes, which is a colon, followed by a comma-delimited list of base classes. A base class can declare a func

The following describes three object-oriented features: inheritance, encapsulation, and polymorphism.
C # is a modern object-oriented language.

1. What is an object?
In the real world, everything is an object. A car, an apple, a table, and a person are all objects.
Objects in C # Represent the structure of data and behavior.
