I have been trying to write tictactoe in c++ but I don't know why the if else statements aren't getting executed.

void Welcome() // FUNCTION1

cout << "\nWelcome to Tic-Tac-toe!!!\n";

After main() starts it inputs the XorO but then it comes down to Wanna play again? Seriously I dunno why:( Sorry for the long program maybe it could have been shorter actually I am learning c++.
