okay, I've got a connect four, 2 player, console game due today, and I've got everything pegged down except for checking for a win, I've tried multiple things, ifs, whiles, fors, and I only have around 5 weeks of experience in C++, with around 15 hrs of class every week.
I'm going to put my code in and see if anyone can help me with this
