I am still working on my tic tac toe game using c++.What I want to do is check an array of characters for X's or O's.If it finds an X or O then it generates another O.It checks the array until it finds an empty spot and then puts an O in that spot.
here is the code I am working on.
if(board[player_O]!='X' && board[player_O]!='O')
{
board[player_O]='O';
}
else
{
player_O_two=rand()%9+1;
}
ok I am trying to check for a empty spot on a tic tac toe board and then put an X or O in that spot.I dont want the computer to put a O in an already occupied spot.
If all you're actually trying to do is find the first empty space and replace it with an O then this would do it:
//Set all spaces to ' ' when you initialize the board
for (int i = 0; i < 8; ++i) //Where 8 is the size of the board
{
board = ' ';
}
//Then when you're wanting to replace the first empty space wth 'O'
for (int i = 0; i < 8; ++i)
{
if (board == ' ')
board = 'O';
}

{
if (board == ' ')
board = 'O';
}
if you do not put a break in that if statement, it will change ALL empty spaces into O's, rather than the first one you find
If (board =='')
{
board = 'O';
break;
}
that way only one empty is changed
also i think you may want 9 instead of 8; arent there 9 tiles in TTT?

You're right, I forgot to put that break in there. Thank you for correcting that
Also, 0 is counted as a space so in an 8 space array there is in fact 9 spaces.
