bool possibleMove(int place)
{
	if(board[place-1] == 'X' || board[place-1] == 'O')
        return false;
	else
        return true;
}



i also want to add in a random number generator that i wrote last week to choose the computers move rather then a 2nd player, any help with the comments in the code or with adding in a random number generator.
long double main (999)
For a (pseudo)random number generator, this should do:

The code you posted, I presume? Nobody will do that. If you write code, you're expected to know what you're writing. Did you write the code?
