A better way to fix it is to wrap the function in ado ... while(0)construct. This construct requires a semicolon at the end, which is exactly what we want. Usingwhile(0)ensures that the loop never really loops, and its contents are only executed once. #defineTIME(name, lastTimeVaria...

以下叙述正确的是___。 A. 可以把define和if定义为用户标识符 B. 可以把define定义为用户标识符,但不能把if定义为用户标识符 C. 可以把if定义为用户标识符,但不能把define定义为用户标识符 D. define和if都不能定义为用户标识符 相关知识点: 试题来源...
A. define、IF、Type B. gect、char、printf C. include、scanf、case D. while、go、pow相关知识点: 试题来源: 解析 define、IF、Type 解析】-|||-答案:-|||-:define是宏定义预处理指令,不是语言-|||-的关键字,是语言的关键字,但是语言区分-|||-大小写,所以IF不是关键字,type没有此关键字。-||...

This is a function declaration; it does not provide the body of the function, but it does tell the compiler that it can use this function and expect that it will be defined somewhere. What it Means to Define Something in C and C++ ...

define在c语言中的作用就是方便程序段的定义和修改，可以将一个变量强制定义为你想要的值。在程序执行期间其值可以改变的量称为变量，变量类型又分为系统变量和用户自定义变量。define在c语言中怎么用 比如：在程序开头有一句：#define a 5，那么在整个程序中，变量a的值就是5，程序编译时也会用5去...
