Is there no way that I can just open a console and use cout/cin?

seems like quite a complex process just to write to a console.

This code looks vaguely familiar ... someone else was asking about a similar problem a couple weeks ago.

DavidCrow wrote:

Same person. Still using sscanf() for validation, even though you provided him an alternative!

DavidCrow wrote:

I thought about this (i.e., using an int), but since he was storing the input string for later processing, I left it as a string.

Harold_Wishes wrote:

1) I want the user to be able to bypass keyboard entrys when they hit ENTER if they choose to skip a question. Now when I hit ENTER, the program will not let me go to the next cout prompt. It is waiting for something other than "\n" character. I believe this is why I used my getline implementation.

Harold_Wishes wrote:

2)Also, if I type in something like "new terminal", such entrys delimited by a space seem to cause the next cin input to read in the second string. But I need to test the output some more with this second issue since I'm getting other strange results.
