IT SHOULD BE IN C$++$

Tic$-$Tac$-$Toe, Portfolio One

$$ Background Information

Tic$-$tac$-$toe is a game for two players who take turns marking the spaces in a three$-$by$-$ three grid with an $"$X$"$ or $"$O$".$ The player who puts three of their marks in a horizontal, vertical, or diagonal row is the winner. You can see a full writeup of the rules and a bit of game theory behind tic$-$tac$-$toe on its Wikipedia page.

$$ Problem Statement

Implement a human versus human game of tic$-$tac$-$toe that can be played on the

command line.

$$ Acceptance Criteria

$$ You should implement a human vs human game of tic$-$tac$-$toe. o Computerplayersarenotrequiredforthissubmission. o Player$1$is$$X$$andPlayer$2$is$$O$.$

o Thegameisplayedona$3$x$3$board.

o Thisgameoftic$-$tac$-$toeshouldimplementallthe$$classic$$rules$$e$.$g$.$ players take turns marking the board, three marks in a row wins, etc.

$$ As a tic$-$tac$-$toe player, when I start the program, I should see:

o Anicelyformattedboardconsistingofa$3$x$3$squaregridofcells.Thecells

As a tic$-$tac$-$toe player, after I make an invalid move, I should see:

o Theboardinitscurrentstatewithnoadditionalmovesmade o Aprompttellingmethatmymovewasinvalidandtotryagain.

When the game ends:

o Itshouldtellmewhichplayerwonorifthegameendedinadraw.

o Itshouldpromptmetoplayagain.

If I choose to play the game again, it should start a brand new game with a cleared

board.

The program should warn a user when an input is invalid. This applies when a user

enters a cell position and when a user decides to play again. Some validations include:

o Acellisalreadytaken.

o Astringorcharinputinsteadofaninteger$($orviceversa$).$ o Randomorunexpectedsymbols.

o Randomwhitespace.

o Adecimalnumberinsteadofanintegerforthecellinput. o Noinput$($justpressingenter$).$

Your program should not crash from user input!
