Solution:
Making a game like tic-tac-toe is a very basic level program but not that easy to understand. So, you can’t expect aa easy set of code from anyone. It has to contain a set of methods and steps at least to fulfill the requirements of a Tic-Tac-Toe game.
However, I am tried to keep it simpler for your better understanding. Please have a look.
#include <iostream>
#include <string>
using namespace std;
class TicTacToe{
private:
char board[3][3];
public:
TicTacToe() { }
void setTable(){
int n = 1;
for(int x = 0; x < 3; x++){
for(int y = 0; y < 3; y++){
board[x][y] = '0' + n;
n++;
}
}
}
void printTable(){
for(int x = 0; x < 3; x++){
for(int y = 0; y < 3; y++)
if(y < 2) { cout << board[x][y] << "|"; }
else { cout << board[x][y] << endl; }
if(x < 2) { cout << "-+-+-\n"; }
}
}
void playerMove(char num, char player){
bool wrongMove = true;//wrong move
for(int x = 0; x < 3; x++){
for(int y = 0; y < 3; y++)
{
if(board[x][y] == num){
board[x][y] = player; wrongMove = false;
}
}
}
if(wrongMove == true) { cout << "Wrong move!\n"; }
}
bool checkWinner(char player, bool gameOver)
{
for(int x = 0; x < 3; x++)
if(board[x][0] == board[x][1] && board[x][1] == board[x][2]) gameOver = true;
for(int x = 0; x < 3; x++)
if(board[0][x] == board[1][x] && board[1][x] == board[2][x]) gameOver = true;
if(board[0][0] == board[1][1] && board[1][1] == board[2][2]) gameOver = true;
if(board[0][2] == board[1][1] && board[1][1] == board[2][0]) gameOver = true;
if(gameOver == true)
{
cout << "Player " << player << " wins!\n\n";
}
return gameOver;
}
bool checkDraw(bool gameOver)
{
int n = 1, count = 0;
for(int x = 0; x < 3; x++)
{
for(int y = 0; y < 3; y++)
{
if(board[x][y] == '0'+n) { count++; }
n++;
}
}
if(count < 1) { cout << "It's a draw!\n\n"; gameOver = true; }
return gameOver;
}
};
int main()
{
bool done = false, gameOver = false;
char player = 'O', num;
TicTacToe myGame;
myGame.setTable();
do
{
if(player == 'X') { player = 'O'; }
else { player = 'X'; }
myGame.printTable();
cout << "Player \"" << player << "\" turn or (q) to quit> ";
cin >> num;
cout << "\n";
if(num == 'q') { cout << "Goodbye!...\n"; break; }
myGame.playerMove(num, player);
gameOver = myGame.checkWinner(player, gameOver);
gameOver = myGame.checkDraw(gameOver);
if(gameOver == true)
{ myGame.setTable();
gameOver = false;
}
}while(!done);
system("pause");
return 0;
}
Thank you too.
