C语言函数

函数名: fgetchar

功 能: 从流中读取字符，赋给一个字符变量。出错返回EOF。

用 法: int fgetchar(void);

程序例:

#include <stdio.h>

int main(void)

{

char ch;

/* prompt the user for input */

printf("Enter a character followed by \\<Enter>: ");

/* read the character from stdin */

ch = fgetchar();

/* display what was read */

printf("The character read is: '%c'\",ch);

return 0;

}

在Visual C + + 2005开始，这是推荐使用的POSIX函数。使用ISO C + +遵从的_fgetchar代替。

原文：This POSIX function is deprecated beginning in Visual C++ 2005. Use the ISO C++ conformant _fgetchar instead.

MSDN中例子：

// crt_fgetchar.c

// This program uses _fgetchar to read the first

// 80 input characters (or until the end of input)

// and place them into a string named buffer.

//

#include <stdio.h>

#include <stdlib.h>

int main( void )

{

char buffer[81];

int i, ch;

// Read in first 80 characters and place them in "buffer":

ch = _fgetchar(); for( i=0; (i < 80 ) && ( feof( stdin ) == 0 ); i++ )

{

buffer[i] = (char)ch;

ch = _fgetchar();

}

// Add null to end string

buffer[i] = '\\0';

printf( "%s\", buffer );}

Input

Line one.

Line two.

Output

Line one.

Line two.
