Defined in header <stdio.h>
int getchar(void);

Reads the next character from stdin.

Equivalent to getc(stdin).

Parameters

(none)

Return value

The obtained character on success or EOF on failure.

If the failure has been caused by end-of-file condition, additionally sets the eof indicator (see feof()) on stdin. If the failure has been caused by some other error, sets the error indicator (see ferror()) on stdin.
