  Proficient classes and objects     This article is based on the knowledge of classes and objects that you already know.           Dynamic Memory Allocation in the object: If the memory is dynamically allocated to the object, the memory should be

    1. There are two points of view for the const modified member functions: logic constness and bitwise constness. Bitwise constness's point of view is: "It does not change any bit of the object". In this way, the compiler only needs to assign

  Global variables in c ++ 1. location that can be defined Function external body of the file where the main function is located Functions of other cpp files in Vitro It cannot be placed in the H file, because the H file may be referenced multiple

Copy constructor is a special constructor with a single parameter. This parameter (commonly used for const modification) is a reference to this type. When you define a new object and initialize it with an object of the same type, the copy

Why do we need to introduce friend functions?Because we cannot have private variables in the external callback class of the class. Traditional access methods: // ================================================ =======================================

14.7 auto-increment operators and auto-subtraction Operators1. Define the auto-increment/auto-increment OperatorsThe C ++ language does not require the auto-increment or auto-subtraction operators to be class members. However, because these

For common objects, copying between them is very simple, for example:Int a = 88;Int B =;Different from common objects, class objects have complicated internal structures and various member variables. The following is a simple example of copying a

17.2 namespace Namespace provides a more controllable mechanism to prevent name conflicts. namespaces can be divided into global namespaces, making it easier to use independently developed libraries. A namespace is a scope. You can define the name,

17.3.2 conversion and multiple base classes In the case of a single base class, the pointer or reference of the derived class can be automatically converted to the pointer or reference of the base class. This is also true for multi-inheritance, the

C ++ keyword explicit  Description: In C ++, the explicit keyword is used to modify the constructor of a class. The class of the constructor to be modified cannot undergo corresponding implicit type conversion. type conversion can only be performed

Single Responsibility Principle (SRP.Definition:There shoshould never be more than one reason for a class to change.There should be only one reason for the change. Sometimes, developers may have some problems when designing interfaces. For example,

[Cpp] # include # Include # Include # Include # Include # Include # Include # Include Using namespace std; Class Point{Public:Point (double x, double y ){};Point (Point & p );Private:Double x, y;}; Point: Point (Point & p): x (p. x), y (p. y){Cout } 

I have mentioned ScopeExit before (see how to organize this code structure? Goto or do... While (0)? Http://www.bkjia.com/kf/201205/132632.html ). The usage scenario is briefly described as follows:Bool GenFile (){HANDLE hFile = CreateFile (_ T

To dynamically allocate a two-dimensional array in C/C ++, You can first apply for a one-dimensional pointer array, and then apply for an array for each pointer in the array, which is equivalent to a two-dimensional array, however, this method may

After graduating from college, I used to write all the algorithms in the data structure book, but it was not enough ..After I learned to use sort in STL, I never wrote too fast. In the future, I want to write these words slowly .. Step by step.#
