Can't input "win" or "tie" in tic-tac-toe

persontothe (13)
Hi I have a tic-tac-toe project for my basic c++ class. I am at a good start but I don't know how to code a win,tie, or a loss in it. here is my current code. Right now I am using a while loop so it plays infinitely since none of the spaces will equal 7. It is in the player actions function.

I know this is annoying and won't answer your question but instead of system("PAUSE"); try to use
1
2
 
cin.ignore();
cin.get();

It's alright any advice is good advice I'll edit that into my program.Can you explain why that is better though? I'm still trying to figure it out but no luck so far except maybe at the end I could manually put in a loop that checks for the winning moves but that would take a long time and I know I would get points taken off for not having more efficient coding.

uzferry, read the "Console closing down" thread before posting that again :)
cin.ignore(numeric_limits<streamsize>::max(), '\n');

@persontothe
How, in real life, would you know when there was a winner or a cat? See if you can convert that logic to code ;)
