I'm not sure what you mean.  If you want an individual character, then
why not just use (c - '0'), as in the following:

int getdigit( void )
{
    int c;
    printf( "Type a digit:  " );
    fflush( stdout );
    while ( ( c = getchar( ) ) < '0' || c > '9' )
        printf( "Please type a digit.\n" );
    return c - '0';
}
