I just need to know of a simple way to get a user input but without them having to press enter after they give their answer.. so if the answer to question "a" was "1", the person would only have to press "1" and that would act like it entered 1, then pressed enter..

This is not possible with standard C/C++. You must use non-portable code. The code you use depends upon your operating system and platform, which is why the posting guidelines recommend including that information with your questions.

There is not a portable way because there is not a world standard way of getting input and producing output. Some people are blind, some are paralyzed, some have home-built systems, some systems have no UI per se. You get the picture.

what is wrong with hitting enter? If the user accidently hit 2 when they meant to hit 1 in your method they'd get the question wrong unfairly. But by having to hit enter they'd have the chance go back and correct their mistake. Im just curious why you need the input immediately. good luck.

It's not that i need it, its because im making a game and there is a shop to buy items at, i just want to name the items on the screen on a list in numbers so 1. shoes, 2. shirt.. ect. But after selecting the item it will ask "do you really want to purchase this item" or something along those lines, having to press enter just makes it more work i guess, its just one of those little things that i want to change in the game. Its not really needed though so ill do without it until i decide enter is really pissing me off.

And another thing: what if you have a number higher than 9?

jayme · Dec 10th, 2005, 12:15 PM

ah... never thought of that :eek:

well you could do a.) item, b.) item, etc. That would give you 16 more single digit possibilities.

DaWei · Dec 10th, 2005, 2:36 PM

Along those lines, you could also have the choices, !, @, #, $, %, etc., and have even MORE single-character possibilites.
