Header File

Category

Console I/O Routines

Prototype

int getchar(void);

wint_t getwchar(void);

Description

Gets character from stdin.

getchar is a macro that returns the next character on the named input stream stdin. It is defined to be getc(stdin).

Note: Do not use this function in Win32 GUI applications.
Return Value

On success, getchar returns the character read, after converting it to an int without sign extension.

On end-of-file or error, it returns EOF.

Example

Copy Code

    #include <stdio.h>
    int main(void)
    {
       int c;
    /*
    Note that getchar reads from stdin and is line buffered; this means it will not return until you press ENTER.
     */
       while ((c = getchar()) != '\n')
          printf("%c", c);
       return 0;
    }
