c# constructor initializer

InArticleBefore getting started, I first pointed out two common misunderstandings about C ++ beginners: 1. If no default constructor is defined for any class, it will be merged. II. The default constructor synthesized by the compiler will explicitly set the "default value for each data member in the class" First, let's discuss the first misunderstanding.

Now I want to read it again, and write the read part, b

content, but they store a different string of locations. To summarize the basic concepts and knowledge you need to know about deep copies and shallow copies: (1) When to use the copy function.A. An object passes through the function body in a way that is passed by value;B. An object is returned from a function in a way that is passed by value;C. An object needs to be initialized with another object.If you do not explicitly declare a copy

C + +, a copy constructor is generated by default, and when a pointer appears in a class, the copy performs a shallow copy, that is, only the address of the pointer is copied, and the data is not copied; So in class, when using pointers, you need to be aware of; If you want to use a deep copy, you can add a copy constructor. The following code, if you do not ad

For some classes, it is best to have an initialization process when used for the first time in a program; when the program is no longer needed, it is best to do some finishing work, which is a very good class design habit. Elicit questions If this is the case, each instance of a type must have its unique ID. For example, a type of transaction that can be used to track each transaction during processing, or later for the auditor to view the data file, for discussion, where the ID is the number

parameters, and the first parameter, according to the above code can know that this is the class name or class itself, at this time, generally by adding "Console.log (CLS)" On the return statement You can tell that there is a problem with that class.The special case is that when the CLS is empty, you don't know where the error is. At this point, you need to add the debugger statement before the return statement, and when the method is called, the browser enters the debug state to check. In fact

constructor. If you want such a constructor, you need to write it out on your own.Complex (void){M_real = 0.0;M_imag = 0.0;} // General constructor (also weigh the loaded constructor) // A General constructor can have various parameter forms. A class can have multiple Gener

Constructor: C ++ provides constructor to process object initialization. It is automatically executed when an object is created. The name of the constructor must be the same as the class name. It does not have any type or return any value. The function of the constructor is

C ++ Object Model -- create a Copy Constructor (chapter 2)2.2 create Copy ConstructorIn three cases, the content of one object is used as the initial value of another class object., The most obvious case is to perform an Explicit initialization operation on an object, for example: Class X {...}; X x X; // use the content of one object as the initial value of another class object x xx = X;In the other two ca
