Access modifiersIn an application, access modifiers can be used to decorate class member fields and methods to qualify a class member's accessibility level. Declaring members of a class (variables or methods) as public means that these class members

Static is a very common modifier in C + +, it is used to control the storage and visibility of variables, and I will analyze the nature of the static modifier from the reason of the static modifier.The two main functions of static:First, control the

Templates are tools that support parameterized polymorphism in C + +, using templates that enable users to declare a generic pattern for a class or function so that some data members or member functions in a class get arbitrary types of parameters

Recently written tests, often encountered the need to quickly split the string, mainly in the process of input, and previously practiced algorithm or written examination, many times do not spend time to consider the test case input problems. However,

There are no input and output statements in the C language, and all input and output functions are implemented using a set of standard library functions provided by ANSI C. The file Operations standard library functions are:File opening operation

Understanding Reference FoldingArticle 23 mentions that when you pass an argument to a template function, the inferred template parameter contains the encoded information, regardless of whether the argument is an lvalue or an rvalue. The clause did

Now look at what the compiler optimizations will do to the generated instructions, and then introduce the volatile qualifiers for C. First look at the following C program:/*Artificial Device Registers*/unsignedCharrecv;unsignedCharsend;/*Memory

//clause 32: Determine your public inheritance mold out is-a relationship//1.public inheritance implies a is-a relationship, and the methods that apply to the base class can be used on derived classes. //Article 33: Avoid hiding the inherited name//1

Because the code you see today uses the coercion type conversion of a struct, it's very important to know what a forced type conversion of a struct is. A struct is as follows: in the following code, RBUF->REQCMDBUF is a null pointer, first

When we start using the C language to handle strings, we get a lot of trouble. The C language lacks the corresponding string handler function, and if you want to implement a string function, we can do it by ourselves. But when it comes to C + +, the

From:http://www.cnblogs.com/akwwl/p/3232679.html A delegate is a class that defines the type of the method so that the method can be passed as a parameter to another method. An event is a special kind of delegate. 1. Declaration of Delegation (1).

1: When a class implements an interface, it is usually implemented using an implicit interface, which makes it easy to access interface methods and the methods and properties that the class itself has2: When the class implements multiple interfaces
