copy assignment operator

C ++ copy constructor, copy assignment operator, mobile constructor, mobile assignment operator, destructor, right value reference, reference qualifier instance, right value of Constructor13.1 copy, assign value, and destroy 13.1.1 copy

Copy constructor If the first parameter of a constructor is a reference to its own class type, and any additional arguments have default values, this constructor is a copy constructor. Copy constructor The first argument must be a reference type.

C ++-copy constructor, copy-assignment operator, destructor, assignmentoperator For a class, copy constructor, copy-assignment operator, move constructor, move-assignment operator, and destructor are collectively referred to as copy control. Let's

For a class, we refer to copy constructor, copy-assignment operator, move constructor, move-assignment operator, destructor collectively as copy ControlToday we first talk about the copy constructor, copy-assignment operator destructor these

Assignment operator The assignment symbol "=" is the assignment operator, which is to assign a data to a variable. The function of "a=3" is to perform an assignment operation (or assignment operation). Assign the constant 3 to variable a. You can

First, make it clear: The system has provided the default copy constructor and the = copy operator. That is, the so-called shallow copy. But sometimes we have to provide our own rewrite. Generally, it is rewritten with pointers. For a simple example,

Note: classes that contain dynamically assigned members should provide copy constructors and overload the "=" value assignment operator. The following examples will be used: Class cexample {public: cexample () {pbuffer = NULL; nsize = 0 ;}~ Cexample

In C + +, there are three major functions of copy control (copy constructor, assignment operator, destructor), and in C++11, move constructor is added to move assignment operator. I would venture to name them six functions.First, the constructor
