Beginner's Project: Tic-Tac-Toe

                              Now as you all are known with the rules about how to play the game, let's design code based on these rules:

Secret Strategies to win Tic-tac-toe:

1)Tic-tac-toe is a very mindful game. You have to be aware of every move of your opponent and even figure out which move you will make next.
2)To beat your opponent, be it a person or a computer even, you need to plan out a strategy.
3)You first need to figure out how you can make those three X’s in a row and stop your opponent from winning as well.
4)Watch your opponent’s every move. For example, if they put two O’s in a row, then you MUST put an X in the next square to those consecutive O’s or you’ll lose.
5)In short, you must be very vigilant while making your moves. This is the only way you’ll never lose a game of tic-tac-toe. If you’ll not win then at least you will have a tie

                              Here’s a beginner project: Tic Tac Toe. The code below contains the solution needed to create a tic tac toe game.
Code:
#include <iostream>
using namespace std;
char square[10] = {‘o’,’1′,’2′,’3′,’4′,’5′,’6′,’7′,’8′,’9′};

int checkwin();
void board();

int main()
{
int player = 1,i,choice;
char mark;
do
{
board();
player=(player%2)?1:2;

cout << “Player ” << player << “, enter a number: “;
cin >> choice;

mark=(player == 1) ? ‘X’ : ‘O’;

if (choice == 1 && square[1] == ‘1’)
square[1] = mark;
else if (choice == 2 && square[2] == ‘2’)

square[2] = mark;
else if (choice == 3 && square[3] == ‘3’)

square[3] = mark;
else if (choice == 4 && square[4] == ‘4’)

square[4] = mark;
else if (choice == 5 && square[5] == ‘5’)
square[5] = mark;
else if (choice == 6 && square[6] == ‘6’)

square[6] = mark;
else if (choice == 7 && square[7] == ‘7’)

square[7] = mark;
else if (choice == 8 && square[8] == ‘8’)

square[8] = mark;
else if (choice == 9 && square[9] == ‘9’)

square[9] = mark;
else
{
cout<<“Invalid move “;

player–;
cin.ignore();
cin.get();
}
i=checkwin();

player++;
}while(i==-1);
board();
if(i==1)
cout<<“==>aPlayer “<<–player<<” win “;
else
cout<<“==>aGame draw”;

cin.ignore();
cin.get();
return 0;
}

cout << ” | | ” << endl << endl;
}

let's look for different algorithms of implementation of this game in further blogs....
