header problems

[TechStudent]

I have struggled and struggled to get this Tic Tac Toe program working. I cannot get it to work without header errors. It did run but only once through and with the player 1 being the computer and player 2 being the user even though it asks for Player 1 to enter their name. Any help would be greatly appreciated. Thank you!

You seem to have copied the code in a way that caused it to lose all indentation - could you fix the indentation? It would help a lot for reading your code.

What specifically are you having trouble with? It is best if we focus on one thing at a time.

Right now the only issue with your program is that you have void main() instead of int main() - in C++, main must return int.
