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?
Regards,
Olof

Heya, Olof. Welcome to TSDN!
I presume you're writing this application in C?
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.

Dang. Thanks for catching that, Ganon11!

I'm importing a large file (213 MB) and parsing it. My question is: does the VB6 Line Input read the whole file, then select out each line, or actually only read that line. I thought it was the second case, but when I'm reading this file, it stalls like no other. A similar smaller file works, but I'm not sure that it should make any difference. (And STD_PROCESSES.Gen_Rec.Record_Type is just a fixed length string*1000)

Hi I have a question, it's probably very basic but I'm still learning the Javascript basics.
The following form outputs a string change (from "input" to "text" box ). When the word "test" is inputted, it changes to "good".
Simple question: If there is no matching string, how would I get the form to just display nothing at all?
Thanks!

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
