    Question Taking chars into account.

    OK, not-so-hypothetical here:

    Say I had a input that, the majority of the time, expected an integer value. But, there is a single case where a char would be acceptable (ie instead of entering an integer, you'd press Q to enter a quit function).

    Is there a nice and clean way of doing this? I know scanf() wasn't designed to do this, and I'm stumped as to what other *scan*() function would do this.

    Thanks in Advance,

    You could just always read in a char and when it's not a Q, then convert it to an integer (atoi()).

    But it's not going to be a single digit all the time (excuse me if I show my newbieness, but I thought that %c would mean only 1 character period, including numbers). Doing it that way, I'd have thought that I'd lose all digits after the first.

    Again, please tell me if my reasoning's faulty

    Then read in a string. =)

    Right. That just seemed so obvious...
