C++

Please fix some problems with my Tic Tac Toe Program:

a. It should declare the winner. Like "Congratulations!
Player X
has won the game!"

b.  A box is already chosen by a player, but if you repeat the location, it changes instead of displaying that it's already occupied.

c. Supply the algorithm needed for a Draw/Tie.
