Explanation / Answer

Answer:

#include <iostream>

using namespace std;

char location[10] = {'o','1','2','3','4','5','6','7','8','9'};

int checkwinner();
void displayboard();

int main()
{
int player = 1,i,choice;

char mark;
do
{
displayboard();
player=(player%2)?1:2;

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

mark=(player == 1) ? 'X' : 'O';

if (choice == 1 && location[1] == '1')

location[1] = mark;
else if (choice == 2 && location[2] == '2')

location[2] = mark;
else if (choice == 3 && location[3] == '3')

location[3] = mark;
else if (choice == 4 && location[4] == '4')

location[4] = mark;
else if (choice == 5 && location[5] == '5')

location[5] = mark;
else if (choice == 6 && location[6] == '6')

location[6] = mark;
else if (choice == 7 && location[7] == '7')

location[7] = mark;
else if (choice == 8 && location[8] == '8')

location[8] = mark;
else if (choice == 9 && location[9] == '9')

location[9] = mark;
else
{
cout<<"Invalid move ";

player--;
cin.ignore();
cin.get();
}
i=checkwinner();

player++;
}while(i==-1);
displayboard();
if(i==1)

cout<<"==>Player "<<--player<<" win ";
else
cout<<"==>Game draw";

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

int checkwinner()
{
if (location[1] == location[2] && location[2] == location[3])

return 1;
else if (location[4] == location[5] && location[5] == location[6])

return 1;
else if (location[7] == location[8] && location[8] == location[9])

return 1;
else if (location[1] == location[4] && location[4] == location[7])

return 1;
else if (location[2] == location[5] && location[5] == location[8])

return 1;
else if (location[3] == location[6] && location[6] == location[9])

return 1;
else if (location[1] == location[5] && location[5] == location[9])

return 1;
else if (location[3] == location[5] && location[5] == location[7])

return 1;

&& location[4] != '4' && location[5] != '5' && location[6] != '6'
&& location[7] != '7' && location[8] != '8' && location[9] != '9')

return 0;
else
return -1;
}

void displayboard()
{
system("cls");
cout << " Tic Tac Toe ";

cout << "Player 1 (X) - Player 2 (O)" << endl << endl;
cout << endl;

cout << " | | " << endl;
cout << " " << location[1] << " | " << location[2] << " | " << location[3] << endl;

cout << "_____|_____|_____" << endl;
cout << " | | " << endl;

cout << " " << location[4] << " | " << location[5] << " | " << location[6] << endl;

cout << "_____|_____|_____" << endl;
cout << " | | " << endl;

cout << " " << location[7] << " | " << location[8] << " | " << location[9] << endl;

cout << " | | " << endl << endl;
