上面1、2、3 类宏通常和条件编译预处理指令 #if/#ifdef/#ifndef 配合使用 辅助类^ __VA_ARGS__: 在函数式宏中,代表变长部分参数 (...),参考 MSDN:Variadic Macros __COUNTER__: include 展开编译单元后,编译时第一次遇到 __COUNTER__ 替换为 0,以后在这个编译每遇到一次 __COUNTER__ 自增一。不同...
#ifdef MAX//判断这个宏是否被定义printf("3 and 5 the max is:%d\n",MAX(3,5));#endif#ifdef MIN printf("3 and 5 the min is:%d\n",MIN(3,5));#endifreturn0; }/** (1)三元运算符要比if,else效率高 * (2)宏的使用一定要细心,需要把参数小心的用括号括起来, * 因为宏只是简单的文本替...
#define B_PTR( var ) ( (byte *) (void *) &(var) ) #define W_PTR( var ) ( (word *) (void *) &(var) ) 10、得到一个字的高位和低位字节 #define WORD_LO(xxx) ((byte) ((word)(xxx) & 255)) #define WORD_HI(xxx) ((byte) ((word)(xxx) >> 8)) 11、返回一个比X大的...
The two forms of the syntax are: Syntax#define identifier token-stringopt#define identifier( identifieropt, . , identifieropt ) token-stringoptUsage:1. 简单的define定义#define MAXTIM 2、E 1000 一个简单的MAXTIME就定义好了,它代表1000,如果在程序里面写if(i(y)?(x):(y);这个定义就将返回两个...

Note: If the scope is a shared scope, you will not be able to edit its settings. Shared scopes are configured in Central Administration. In the Title box, type a word, name, acronym, or short phrase to describe the scope. The title displays in the Scopes list and indicates to the use...
B If you had to use one word to define yourself, what would it be? Imagine trying to summarize your entire being in just one word or two - a challenging task indeed. Labels, like "confident" or "creative", may suggest certain aspects, but they can never fully capture the richness and...

If you can't define a word, turn to the dictionary. That's always the best way to learn the definition. Likewise, anything you can describe completely is something you can define.
