Predefined Shader preprocessor macros 预定义的着色器预处理宏 Unity defines several preprocessor macros when compiling Shader programs. 在编译着色程序时,Unity定义了几个预处理器宏。 Target platform Macro: Target plat...typedef和#define
The C preprocessor is a macro preprocessor (allows you to define macros) that transforms your program before it is compiled. These transformations can be the inclusion of header files, macro expansions, etc. All preprocessing directives begin with a#symbol. For example, ...
The preprocessor expands macros in all lines except preprocessor directives, lines that have a # as the first non-white-space character. It expands macros in parts of some directives that aren't skipped as part of a conditional compilation. Conditional compilation directives allow you to suppress ...
c++macrospreprocessor-directive 4 我的二次幂计算能力不如应该,所以我想也许我可以用#define定义一些东西。 不幸的是,当涉及到预处理器指令时,我非常缺乏经验,而且我无法弄清楚如何做像for循环这样的事情。 我查看了: http://www.cplusplus.com/doc/tutorial/preprocessor https://msdn.microsoft.com/en-us/libra...
Preprocessor macros could be used for very weird things, since all that the preprocessor does is to replace an identifier with an arbitrary piece of source code. For example, the following is legal code (although, you will probably have to answer to your boss if you ever try to write somet...
10. C Preprocessor 10.1I'm trying to define a few simple little function-like macros such as #define square(x) x * x 10.2Here are some cute preprocessor macros: #define begin { #define end } 10.3How can I write a generic macro to swap two values?

CpreprocessorC预处理器在C语言中扮演的角色是处理源代码中的预处理指令，如条件编译、宏展开、文件包含等。这些指令在编译过程中被处理，最终生成的目标代码与预处理器处理的结果紧密相关。而宏语言如InternetMacros(iOpus)M4，它们源于ATT并捆绑于Unix系统，其核心功能是提供一种在源代码中进行复杂替换和...
varcompiler=require("c-preprocessor"); //To compile a file compiler.compileFile(fileName,[options,]function(err,result){ if(err) returnconsole.log(err); console.log(result); }); //To compile a text compiler.compile(code,[options,]function(err,result){ ...
Macros The other major use of the preprocessor is to define macros. The advantage of a macro is that it can be type-neutral (this can also be a disadvantage, of course), and it's inlined directly into the code, so there isn't any function call overhead. (Note that in C++, it's...
