宏命令#include[math.h]与#include"math.h>"等价
举一反三
- 下列#include命令中,正确的是________。 A: B: include "math.h" C: D: include [math.h] E: F: include (math.h) G: H: include {math.h}
- 下列#include命令中,正确的是()。 A: #include<br/>"math.h" B: #include<br/>[math.h] C: #include<br/>(math.h) D: #include<br/>{math.h}
- 如果程序中用到标准库函数sqrt( )和strcmp( )，那么该程序应含下面哪两条语句( ) A: B: include “stdio.h” C: include “math.h” D: E: include “math.h” F: incluede “string.h” G: H: include “string.h” I: include “stdio.h” J: K: include “stdlib.h” L: include ”math.h”
- 以下是一个正确的include命令#include<;math.h>;；
- 如果程序中需要用到数学函数，头文件应该表示为（）。 A: B: include " system.h " C: D: include " math.h " E: F: include " stdio.h " G: H: include " string.h "
