int x = 1234; it is a variable declaration plus definition. Variables can be declared repeatedly, as long as they do not conflict with each other, but can be defined only once.However, const int x = 1234; is also the global definition of "variable" (if declared, it should be const int X;), but can appear in the header file, when multiple CPP files contain this header file, it is equivalent that each CPP fi

Macro: Usually put some commonly used strings, basically leave the definition macro1. Compile time is different: const is compiled at the time of compilation, the macro is compiled at the time of compilation (pre-compilation is the program load, Xcode will have a progress bar, show progress, this time is actually in pre-compilation)2. Compile detection: const has compile detection, and macro does not compile detection3. Benefits of Macros: You can def

From: http://blog.21ic.com/user1/349/archives/2008/48018.html It is recommended to write C language. A beautiful macro definition is very important.

In the previous article, we talked about how to introduce the maste page in site definition. This is a necessary step, but it is definitely not enough, because it is impossible for us to deploy and use the master page without designing it. The appearance design must involve the introduction and use of CSS and other resources. Here we will continue with the above operations. In this article, we will look at how to introduce our CSS resources (of course

The definition constants of constants are case-sensitive by default, if define (' AA ', 20,true) denotes case-insensitive, the output name is generally capitalizedBOOLDefine( string $name , Mixed $value [, BOOL $case_insensitive = False ]) ?
