# C++ Make a Tic Tac Toe game fo

C++ Make a Tic Tac Toe game for 2 players to play using 2Darrays and classes. Do not add more #include functions other thanthe ones listed.

I never said what type of code I needed in a previous question.I apologize and I can’t go back and change it so here is the samequestion with more information

Using the tictactoeGame class, write a main program that uses atictactoeGame to implement a game in which two players (you and afriend) take turns placing X’s and O’s onto the board. After eachturn, the current board configuration should be displayed, and oncea player connects three of a kind, the game should end declaringthat player the winner.

#include#includeusing namespace std;

class tictactoeGame{ public:

charboardConfig[3][3]; // two dimensional array storescurrent board configuration // Constructor: // set boardConfig[i][j]to be ‘ ‘ (the space character) // for 0<= i <= 2,0<= j <= 2 tictactoeGame() { //fill thisin }

//put an ‘X’ character at the givenlocation bool placeX(int x, inty) { //fill thisin }

//put an ‘O’ character at the givenlocation bool placeO(int x, inty) { //fill thisin }

//set all positions to character ‘ ‘. void clear() { //fill thisin }

// Return true ifthere are 3 ‘X’ marks placed in a single // column, row, ordiagnol. Return false otherwise. bool xWins() { //fill thisin }

// Return true ifthere are 3 ‘O’ marks placed in a single // column, row, ordiagnol. Return false otherwise. bool oWins() { //fill thisin }

// Return true ifthere are either 3 ‘X’ marks or 3 ‘O’ marks // placed in a singlecolumn, row, or diagnol, or if the board is full. // Return false otherwise. bool gameOver() { //fill thisin }

// cout a nicelooking picture of the board configuration void display() { //fill thisin }

};

int main(){return 0;}

Answer:

The code has been kept as simpler it could be for betterunderstanding, please use the only integer for the row value(x) andcolumn value(y) asked in the program. If the entered configurationof row and column already filled with X or O in that case code willsay invalid input and ask to enter again, but it is not handled forvalues other than an integer ( for ex. if you enter “asd” in theplace of row and column the program will terminate, if you want meto handle this it will be a little complex if you want, mention inthe comment section, I will provide it too). The explanation of thecode has been added to the comment lines and a sample screenshot ofthe running program has been added in the last as well.
