Read a character from standard input.
int getchar();
wint_t getwchar();
Return Value
Returns the character read. To indicate a read error or end-of-file condition, getchar returns EOF, and getwchar returns WEOF. For getchar, use ferror or feof to check for an error or for end of file.
Remarks
Each routine reads a single character from stdin and increments the associated file pointer to point to the next character. getchar is the same as _fgetchar, but it is implemented as a function and as a macro.
These functions lock the calling thread and are therefore thread-safe. For a non-locking version, see _getchar_nolock, _getwchar_nolock.

Example
// crt_getchar.c
// Use getchar to read a line from stdin.
#include <stdio.h>
int main()
{
char buffer[81];
int i, ch;
for (i = 0; (i < 80) && ((ch = getchar()) != EOF)
&& (ch != '\n'); i++)
{
buffer[i] = (char) ch;
}
// Terminate string with a null character
buffer[i] = '\0';
printf( "Input was: %s\n", buffer);
}
