If you have this book "Beginning C++ through game programming" please advise
I have been going through this book for weeks. In each chapter it gives you a game program at the end and then some "exercises" typically the exercises are relatively easy. The game it gets to are VERY difficult for me to understand. Particularly in chapter 6 "Tic-Tac-Toe." After reading chapter 6 I feel so discouraged as to give up on learning programming. My question is this. I understand all of the individual concepts up to this point but the implementation in the tic-tac-toe program is overwhelming to me. Should I at this point really be able to program this game? I know without a doubt that based on the knowledge I have learned so far in this book I could in no shape or form write this program on my own? If I am capable of doing the exercises at the end of the chapter is that what is to be expected of me or if I cant comprehend this tic-tac-toe program am I so far lost that its pointless
