Input Question

[Ekranoplan]

I have a program that implements Conway's Game of Life. I want it to execute one iteration everytime the user hits the 'enter' key on the keyboard. How would I handle that input?

Heya, Olof. Welcome to TSDN!

I presume you're writing this application in C?

[Ekranoplan]

Ofcourse, how foolish of me. Its written in C++.

Heya, Ekranoplan.

I'm going to go ahead and move this thread to the C++ forum, where our resident Experts will be better able to help you out.

If you're just trying to get an "Enter" (aka \n char), you can use any input method, and discard what is read in. For example

string s_ignoreContentsHere;
 
cin >> s_ignoreContentsHere; // Though this can fill up your input buffer as it stops at whitespace, and will then try to 'refill' as soon as the first part has been read
getline(cin,s_ignoreContentsHere); // probably what I would do
scanf("%s",s_ignoreContentsHere); // you might want to check the buffer on this one, I don't know off the top of my head
 

It just depends on how robust/easy you want to make it.

The problem you'll face there is that the computer will be waiting for the user to type in something other than <enter>, so if the user simply presses enter, it will think it's still retrieving input and not continue with the program's execution. Try cin.get(), which will take the next character entered no matter what - now you can simply press enter to continue.

/sicarie actually does programming

Dang. Thanks for catching that, Ganon11!
