define code

The difference between #define, const, typedef#define is not defining variables, it's just for text substitution.For example:#define PI 3.1415926float Angel;angel=30*pi/180;Then, when the program is compiled, the compiler will first "#define PI 3.141

#define是C语言中提供的宏定义命令, the main purpose is to provide programmers with certain convenience in programming, and to a certain extent, improve the efficiency of the program, but students often do not understand the nature of the command in learning,

Macro definition in many languages can see its shadow, C #, C++,c, and so on, especially the system API inside a lot of macro definition, looking very bluffing people. Reasonable use of macro definition, you can make your code look more standardized,

Definition: The # define Directive You can use the # define directive to give a meaningful name to a constant in your program. The two forms of the syntax are: Syntax # Define identifier token-stringopt # Define identifier [(identifieropt,...,

There are many places in the C language where macro definitions are used, such as in header files to prevent header files from being repeatedly included: #ifndef ctest_header_h #define CTEST_HEADER_H /header file content #endif Many macro

Thanks to http://blog.chinaunix.net/u3/111961/showart_2187819.html first . This is an excellent article. In the last study, we wrote a small client example, which is very simple and the header file generated by using producer-binding-tool is very

Mini-define A simple front-end modular framework based on require implementation. If you don't want to spend time learning require.js, and don't want to look at long CMD/AMD specifications, then this mini-define is a good choice for you. If you've
