  Sometimes some data in the program needs to be permanently saved or called globally for other reasons, but the global data is dangerous for development. Static is introduced here, which is very useful.   I understand static as follows:   When an

  Garbled Code cannot afford to hurt ....   The following is the conversion code...   Inline wstring utf8ToUnicode (string str)   { // UTF8 to Unicode   Size_t wcsLen =: MultiByteToWideChar (CP_UTF8, NULL, str. c_str (), str. length (), NULL, 0 ); //

Design of the role in the game (C language description)Recently I was writing an RPG Game. I used my spare time to design a role module and share it with my friends who love the game. The code is divided into three parts: 1. abstract role class, 2.

Stack and stack differencesI. prerequisites-program memory allocationThe memory occupied by a c/C ++ compiled program is divided into the following parts:1. stack: the stack zone is automatically allocated and released by the compiler, and stores

If you read the source code of Qt, you will see a bunch of strange macros, such as Q_D and Q_Q. Our Qt source code journey begins with understanding these macros. The following is an example of C ++. class Person      {      public:       

Some strategic code, algorithm code, and The code that is not related to the driver's internal API can be used at the application layer for testing, To speed up writing, This is obvious, and the application layer has its advantages in this

Those who have done programming, of course, remember that the console program we learned about programming is always a black window. We try our best to provide standard output in it, but whether or not we have thought about the secrets that the

I. Use of tools1. Learn to use vim/emacs. vim/emacs is the most commonly used source code editor in linux. You must not only use them to edit the source code, but also use them for searching, locating, and replacing. Vim is recommended for beginners,

How to execute analysis programs I) I am used to programming in advanced languages. A few lines of code can be used to implement complicated computing. Have you considered this, how can these lines of code be stored and run on a computer? In the

This is the topic that a netizen asked questions when I first got to work this morning. I personally felt that it was quite common. So I copied my QQ message and compiled it into an article. This is not a big topic, but I think the design principles

Because Apple does not allow apps to download executable code, it cannot use a dynamic link library to build a plug-in engine and download it over the Internet on iOS. However, one way is to integrate a script interpreter inside the engine and use

First of all, although closures are often mentioned, I am not clear about the concept of closures. I vaguely feel that if function A defines and Returns function B, function B can still run normally outside function A and access the variables

Recently, we need to clear the warning in the project. PG does not know much about the differences in programming in Linux and Windows, resulting in a lot of compiling Warning, I can only help them solve the problem sadly. C ++ is less casual than
