Object-oriented terminology Class Class is the code segment used to create an object as a design blueprint. It describes the features of an object, the attributes of the object, the tasks of using the object, and the responses of the

1. Functions defined inside the class implicitly feel inline, the inline function should be defined in the header file, because its definition must be visible to the compiler, so that the compiler can expand the code of the function within the call

A few days ago, our project just solved the stopship bug caused by pure virtual function call. Let's take a look at the hot tie.Theoretical case When a pure virtual function is called, the following dialog box is displayed in the debug mode of vc ++:

I am so busy recently that I have no time to write. It takes only a few minutes. Haha, today aear is talking about class. ctor, namely constructor, and Class. dtor, destructor. I believe everyone knows what constructor and destructor are used for. I

0x00In this section we will discuss the implementation of object inheritance and virtual function assembly.0x01Let's look directly at the assembly code:#include "com_example_ndkreverse6_lesson6.h" #include #define LOG_TAG "Lesson6" #define ALOGD ( .

Most applications use common inheritance for a single base class, but in some cases it is necessary to derive a class from more than one direct base class, known as multiple inheritance, which inherits the properties of all its parent classes.1:

Inheritance1) Inheritance is an important method for object-oriented programming to realize software reuse. A program ape can define a new derived class based on an existing base class.2) A derived class of single inheritance has only one base class.

Properties of the class Abstraction, encapsulation , inheritance , polymorphism , overloading Class and struct differences A struct in C can only contain data members and cannot have member functions, which belong to

Derive a new class from an existing class, called inheritance. Derived classes inherit the characteristics and methods of the base class.Public inheritance: The public member of the base class becomes the public member of the derived class, and the
