1. Lvalue and Rvalue Lvalue: A non-temporary object that can be used within multiple statements. Rvalue: Temporary object, which can only be used within this statement. such as:inti =0;//I is a persistent object, can be used in multiple statements, 0

When we define a class, if it is an empty class, the compiler defaults to providing the default constructor, copy constructor, copy assignment function, and introverted destructor.If you derive a new class that inherits from the empty class, the

Remember:The copy function should ensure that all member variables within the object and all parent components are copied.Do not attempt to implement another copy function with one copy function. Common functions should be placed in a third function

The 1.non-virtual function is parsed at compile time, judging by the type of the object being called!! Remember this.2. Where a base class is defined with one (or more) virtual functions, it should declare its destructor as virtual, but do not

This is the second page of Part 2. Move semantics: Moving from Lvalue Now, if you like to use a copy assignment function to implement your copy constructor, you may also try to implement the move constructor with the move copy assignment function.

The stack in C ++ is a special linear table that only allows the insert and delete operations on the same end. one end of the insert and delete operations is called the stack top, while the other end is the stack bottom, now that we know what Stack

The world of object-oriented programming is centered around explicit interfaces (explicit interfaces) and runtime polymorphism (execution phase polymorphism. For example, the following (meaningless) class (class) is given ).class Widget { 　public: 　　

A very important concept introduced in c++11 is the rvalue reference. Understanding Rvalue references is the basis for learning "move Semantics". To understand rvalue references, you must first differentiate between lvalue and rvalue values.Note:

One of the key decisions that we programmers need to make when embarking on a project is to choose a language, or a set of languages, to implement the system. This decision will not only affect the implementation of the system, but also affect the
