Lanuague: C++ (Beginner level)

*****************************************************************

Create a two PERSON tic tac toe game.

(There is NO computer play)

For example:

If ( x == 1 ) { x1 = \'x\' }
else if ( x == 2 ) { x2 = \'x\'; }
else if ( x == 3 ) { x3 = \'x\'; }
else if....... etc

like wise for \'o\'.

Solution

/*In this program every locatio there are 9 positions . I mean 9 positions (1-9) will show up in the screen. You have to enter the position number to place an \'X\' or a \'0\' accordingly.*/

#include <iostream.h>
#include <conio.h>

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;
   clrscr();
   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--;
           getch();
       }
