1. Concept of function overloadingfunction overloading means that a function can have the same name as other functions in the same scope, but the parameter types, number of arguments, return values, and function functions of the same name functions

Threads are created with the thread class, and the ThreadStart delegate is used to indicate where the method begins to run. ThreadStart's statement is as follows:public delegate void ThreadStart ();After the Start method is called, the thread begins

iterators. Basic introduction (from Network): Iterators are an abstract concept. Ability to traverse some/all elements within a container.  Each iterator contains the address of the element. It can combine abstract containers with generic algorithms.

Cout overload can be written as a member function, if possible, write a function prototype, if not, explain why # include using namespace std;//cout do friend class a;ostream& operatorusing namespace Std;class a{public: A (int n = 0): M (n) {}//cout

Adapter mode (Adapter): Transforms the interface of one class into another interface that the customer wants. Make the original interface incompatible and not work in one of those classes that can work together.Usage Scenario: When the data and

In the next phase, I will explain the object-oriented parts of C + + and the most important part of C + + for the improvement of the language. Previously, C + + was also called "C with Class". Today, we mainly talk about the composition of classes,

The previous essay wrote about C + + in comments, input and output, local variable description of the expansion, and the Const modifier and C in the comparison of # define, also got a few learning C + + friends help Explain, very grateful, I also

Abstract Factory: Provides an interface to create a series of related or interdependent objects without specifying their specific classes.Pros: Easy to exchange product system, because the specific factory class, in an application only need to

After seeing C + +, it is not difficult to look at the object-oriented sense of C #, but there are some differences.1. Class definitionUse The class keyword to declare a class, which differs from C + + in that it does not require a colon after
