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).

Remarque :  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

 #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;
 }
