So ive recently completed a functional tik tak toe program and am now trying to rearange it to a class$/$object structure. As well the constructor TicTacToe::TicTacToe$()$ should initialize the class attributes $($sigil$,$ and board$).$ Theres no need to chance the functions unless necessary.

As well the class interface should consist of

class TicTacToe $\{$

$$public:

$$TicTacToe$()$;

$//$ void play$()$;

$$private:

$//$ Hint: Initialize these attributes in the constructor.

$$char sigil$[3]$;

$$int board$[3][3]$;

$//$ void drawBoard$()$;

$//$ bool isMoveLegal$($int row, int column$)$;

$//$ int winner$()$;

$//$ bool isGameOver$()$;

$\}$;

And the main should look like

int main$()\{$

$$TicTacToe Game;

$//$ Game.play$()$;

$$return $0$;

below is the program at hand

const char SIGIL$[3]=\{\text{'}.\text{'},\text{'}$X$\text{'},\text{'}$O$\text{'}\}$;

$//$ Function Prototypes.

void drawBoard$($int board$[3][3])$;

bool isMoveLegal$($int board$[3][3],$ int row, int column$)$;

int winner$($int board$[3][3])$;

bool isGameOver$($int board$[3][3])$;

void drawBoard$($int board$[3][3])$

$\{$

$$ cout $<<"012"<<$ endl;

$$ for$($int i $=0$; i $<3$; i$++)$

$\{$

$$ cout $<<$ i $<<""$;

$$ for$($int j $=0$; j $<3$; j$++)$

$$ if$($board$[$i$][$j$]==0)$
