C + + object model is an important point of knowledge, learning the memory model of C + + object, we can understand the polymorphism principle in C + +, the class initialization order problem, the class size problem and so on.1 C + + object Model

Inner class, a Class A is defined inside another class B, then we call Class A an inner class1. member Inner classExperimental research:Create Class Testpublic class Test {public static void Main (string[] args) {}} creates a class out representing

Polymorphism in the 1.c++(1) Polymorphism: The invocation of the same function can perform different operations, and function overloading is a means of realizing polymorphism.(2) Link: Join during the compilation phase. That is, the point of Call of

Chapter 13th Class Succession1. class inheritance : Extend and modify classes.2 . Public inheritance format: The colon indicates that the base class of Class B is a, a, or a derived class. Class B:public A{。。。}；3 . The derived class object contains

1. What Is operator overloading You can use participle to interpret operator overloading as: operator + overload. There are a lot of operators in C + +, such as +,-,*,\ and so on. Overloading in C + + is also the embodiment of object-oriented

C ++ provides the class member initialization list for the class. The construction order of class objects is as follows:1. allocate memory. when calling the constructor, the data members are initialized implicitly/displayed.2. After Entering the

I. This The Java keyword "this" can only be used in methods and methods. After an object is created, the Java Virtual Machine (JVM) assigns a pointer to the object to reference itself. The pointer name is this. Therefore, this can only be used in

The construction order of class objects is as follows:1. allocate memory. when calling the constructor, the data members are initialized implicitly/displayed.The initialization phase can be explicit or implicit, depending on whether a member

1. When will the compiler generate appropriate special default functions for the class? When the statement is as follows: Class ca {}; C ++ compilation is generally used to generate five functions silently behind the scenes: default constructor,

In the past, when using Delphi and C #, attributes in the Delphi and C # syntax were very convenient. When reading and writing attributes, the get, set function or code of the attributes could be automatically called. however, my favorite C ++ does

C language Evolution to C + + process, is a camouflage of the development process.1, BOOL type variable: 1 byte variable (same size as char), default assignment is True (1), False (0)2, reference variable: The new application of the variable to hang

One or two-D arrays1. How to defineM: Represents how many one-dimensional arrays are in the current two-dimensional array; N: Represents the length of each one-dimensional array(1) data type [] array name =new data type [M][n](2) data type [] array

Static represents the meaning of "global" or "static", which modifies member variables and member methods, and can also form statically static blocks of code, but there is no concept of global variables in the Java language .member variables and

Class 6.2: When C + + falls in love with object-orientedThe concept of class is the embodiment of object-oriented thought in C + +: It is both the result of encapsulation and the carrier of inheritance and polymorphism. Therefore, to learn the

Asp. NET common face questions and answers1. Describe the access rights of private, protected, public, and internal modifiers.For. Private: A privately owned member that can be accessed within a class.Protected: A protected member that can be

Recently, the decision to seriously begin to record their own way of learning.Access control for C + + classes is public, private, and protected.The first is to divide the simple base class and the derived class case, not very easy to confuse with
