A: #include
"math.h"
B: #include
[math.h]
C: #include
(math.h)
D: #include
{math.h}
A: #include
"math.h"
B: #include
[math.h]
C: #include
(math.h)
D: #include
{math.h}
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}
- 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 "
- 在C程序中如果要使用数学函数,如sin(x),log(x)等,需要在程序中加入 A: B: include <;math.h>; C: D: include <;stdio.h>; E: F: define <;math.h>; G: H: define <;stdio.h>;
