This article is reproduced from here to write the link contentWrite a C + + class in a good waySuppose now we are going to implement a plural class complex, and explore good programming habits in the implementation of classes.Defensive statements in

//1. When defining a class, we show or implicitly indicate that this type of object (note here is the object of this type, not including pointers of this type) copy, move, assign, and do what when destroying. A class controls these operations by

Problem focus: Two copying operations: copy constructor and overload assignment operator. Make sure that all member variables of the Copied object are copied in one sentence. Demo Void logCall (const std: string & funcName); // log function

  Class. There are too many tasks. Let's try to figure it out. A class is a user-defined type. The goal of the class concept in C ++ is to provide a new type of tool for programmers, which can be used as easily as internally. Access control: the

What is the pod type? Pod Full name plain old Data. In layman's words, a class or struct can keep its data intact after a binary copy, so it is a pod type. An ordinary definition1. There are trivial constructors2. There are trivial copy constructors3

For a general object such asint a = 10;int B = 20;Assignment between objects, the copying process is very simple, but for the class object, there are various types of variables inside, the copy process is more complex. In fact, during the object

How to prohibit C + + class support copyThe C + + compiler silently does a lot of work for you When you write downClass Empty {};//is actually equivalent to class empty {public: empty () {...}//default constructor empty (const empty

Catalogue Lvalue, rvalue, lvalue Reference, rvalue reference Rvalue reference and consolidated reference Use rvalue reference, avoid deep copy, optimize program performance std::move

Exercise 13.6is actually the "=" operation, which is the assignment operation. The right operand is passed as a display parameter to the left. Synthetic copy assignment operators prohibit assignment of objects of that type. When a class does not

Conclusion:From the perspective of object programming, the copy constructor calls the overloaded assignment operator, and the overloaded assignment operator calls the copy constructor without meaning. should be avoided.Don ' t try to implement one

Go on ...(b). Construction/Destruction/assignment operations_______________________________________________________________________________________________________________ _____________________Article 11: Handling "self-assignment" in

In general, for a user-defined class type, the following four functions are automatically generated by the compiler when the user does not have a custom condition:1. Default constructor2. Copy constructorSomeclass::someclass (const SomeClass &);3.

Chapter Review:The 1th chapter of effective C + + makes himself accustomed to c++-reading notesEffective C + + 2nd structure/destructor/assignment operation (1)-Reading notesEffective C + + 2nd structure/destructor/assignment operation (2)-Reading

Effective C + + guide (Introduction)Terminology (terminology)A declarative (declaration) is a name and type (type) that tells the compiler something, but omits the details. The following are declarative:extern int x; //

What is the pod type? Pod Full name plain old Data. In layman's words, a class or struct can keep its data intact after a binary copy, so it is a pod type. An ordinary definition1. There are trivial constructors2. There are trivial copy constructors3

Notes will continue to update, there are errors in the place welcome corrections, Thank you! constructors and copy control Virtual destructor Destructors in the inheritance system should be defined as virtual functions.As I've said before, defining

The problem of deep copy and shallow copy in C + + is a point of knowledge that deserves our attention, and if you don't pay attention in programming, you may be negligent and cause a bug. This article tells you a lot about C + + shades.We know that

5.2 Object construction under the inheritance systemWhen defining an object as follows:T object;Whenwhat is actually going to happen?If T has a constructor (either provided by the user or synthesized by the compiler), it will be called. It's obvious
