The design of library is is a compromise process. The ideal library should be short, fast, powerful, flexible, extensible, intuitive, universally applicable, with good support, without constraints, without errors. It's not there either. Libraries

Thread synchronization is the core of multithreaded programming, and its purpose is to correctly handle various problems of multithreading concurrency, such as thread waiting, mutual exclusion when multiple threads access the same data,

The pointer looks completely different from the reference (the pointer uses the operator ' * ' and '-> ' to refer to the operator '. ') ), but they seem to have the same functionality. Pointers and references allow you to indirectly refer to other

When it comes to C, I think all the friends who have learned it have such a feeling, that is "Let me happy let me worry." "Happy is that the C language function is very powerful, widely used, once mastered, you can confidently say to others," I am a

Array In the design of the array, some variables with the same type are organized in an orderly manner for the convenience of processing. These ordered sets of similar data elements are called arrays. In the C language, an array belongs to the

Brief introduction The Visual C + + development team spent a lot of time listening to users ' opinions in the right. NET and C + +, after careful consideration, decided to redesign support for the common language Runtime Library (CLR) in Visual C +

Most people use the Ping command just as a simple way to see if the network connection to another system is normal. In this article, the author describes how to write a program that simulates the ping function in C language. The ping command is a

Processing function keysThe problem with the function key is that the user interface is not fixed, and the selection of the user function key will make the screen picture appear in a different display state. For example, the main screen is shown in

Reserved word this is only used in constructors, class methods, and instances of classes, and it has the following meanings: This appears in the constructor of the class as a value type that represents a reference to the object itself being

1. For smart pointers, safety first, convenient second, as localized as possible (SCOPED_PTR); 2. The reference form participates in the const, otherwise the pointer parameter is used; 3. Use of function overloads to be clear and readable 4. The use

There are two main ways in which a dynamic library is linked to an application: implicit linking and explicit linking. Implicit linking is a common method. If the application and dynamic libraries are developed separately on different development

Seventh lecture fields and attributes Domain A field (field), also known as a member variable (Variable), represents a storage location and is an integral part of the class in C #. The type of the field can be any data type in C #. However, for

We have already learned how language like Visual Basic or Delphi implements the capture of screen images. So how do you implement this functionality for C #? This article is to explore this issue. A Program Design Development and operating

In modern advanced languages, most languages have keywords for handling exceptions, such as the try/except/finally in Try/catch,delphi in C + +, which are directly supported by the compiler. However, when Symbian OS C + + was invented, the keyword
