C标准函数库中提供了一些输入输出函数,以下正确的头文件包含命令是()
A:
B: include <;studio.h>;
C:
D: inlcude <;stdio.h>;
E:
F: include "stdio.h"
G: include "stdio.h"
A:
B: include <;studio.h>;
C:
D: inlcude <;stdio.h>;
E:
F: include "stdio.h"
G: include "stdio.h"
举一反三
- 使用库函数前包含头文件stdio。h的正确命令是( )。 A: @include<stdio.h> B: #include<stdio.h> C: #include stdio.h D: #include”stdio.h”
- c程序实现输入输出的函数头文件是什么? A: stbin.h B: stdi.h C: stdio,h D: stdio.h
- 使用scanf()函数时,在源程序开头必须写预处理命令( ) A: include <stdio.h> B: include <stdio > C: include <stdio.h> D: include <scanf.h>
- 以下写法正确的有() A: B: include{stdio.h} C: D: include(stdio.h) E: F: include; G: H: include"stdio.h"
