C1 condition include As follows: Code # Ifndef main_h _ # Define main_h _ Other content # Endif When we see the header file, the function is to prevent this header file from being included multiple times. Repeated definitions occur when multiple include operations are performed. Therefore, you must use this definition in each header file. If you still don't know how to use it, you can see the standard header file of C, such as fcntl. h. 2. Conditional compilation As follows: Code # Ifdef _ deb

#define宏定义在C系开发中可以说占有举足轻重的作用. The underlying framework does not have to say, in order to compile optimization and convenience, as well as cross-platform capabilities, macros are heavily used, it can be said that the bottom of development left define will be unable to move. When developing at a higher level, we put more emphasis on business logic and seem to have little use and reliance on macros.But the benefits of using macro definitions are self-exp

#springMessage ("xxx") to deal with internationalization:The way spring handles internationalization can be very special, because this tag can be used.This tag is used only after spring has integrated the velocity template. This template is available in:Org.springframework.web.servlet\src\main\java\org\springframework\web\servlet\view\velocity\spring.vmThe first macro in the velocity template is the springmessage tag, and there are other markers, whic

In the book or the novel print, you do not set reverse order printing, then the paper will need to be rearranged, because the first page is placed in the bottom, many words obviously not that time to another one of the tune.
