Thread: Please help!

This is my code:

Code:

#include <iostream.h>
#include <stdio.h>
#include <time.h>
#include <stdlib.h>

char playagain='y';
char number;
char array[10];
char i='1';
char compnumber;
int main(void)
{
	array[1]='1';
	array[2]='2';
	array[3]='3';
	array[4]='4';
	array[5]='5';
	array[6]='6';
	array[7]='7';
	array[8]='8';
	array[9]='9';
	srand(time(NULL));
	compnumber=rand()%10;
	while(playagain=='y')
	{
	i=1;
	cout << array[1];
	cout << "|";
	cout << array[2];
	cout << "|";
	cout << array[3];
	cout << "\n-----\n";
	cout << array[4];
	cout << "|";
	cout << array[5];
	cout << "|";
	cout << array[6];
	cout << "\n-----\n";
	cout << array[7];
	cout << "|";
	cout << array[8];
	cout << "|";
	cout << array[9];
	cout << "\n";
	cout << "Please enter the number of the space you would like to place an X in: ";
	cin >> number;
	for(i=i-'0';i<10;(int)i++) // Player number calculation
	{
		if(number==i+'0' && array[i]!=i+'0') //Space already taken
		{
			cout << "That space is taken!\n";
		}
		if(number==i+'0' && array[i]==i+'0') //Assigns X
		{
			array[i]='X';
		}
	}
	if((array[1]=='X' && array[2]=='X') || (array[1]=='O' && array[2]=='O')) //Computer AI. Stops player win or finishes computer win.
	{
		compnumber='3';
	}
	if((array[1]=='X' && array[5]=='X') || (array[1]=='O' && array[5]=='O'))
	{
		compnumber='9';
	}
	if((array[1]=='X' && array[4]=='X') || (array[1]=='O' && array[4]=='O'))
	{

	}
	if((array[3]=='X' && array[6]=='X') || (array[3]=='O' && array[6]=='O'))

	}
	if((array[4]=='X' && array[5]=='X') || (array[4]=='O' && array[5]=='O'))
	{

	}
	else;
	{
	for(i=i-'0';i<10;(int)i++) //Computer random number
	{
		while(compnumber==i+'0' && array[i]!=i+'0') //Space taken
		{
				compnumber=rand()%10;

		}

	}
}
return 0;
}

It's supposed to be a tic-tac-toe game, but the computer won't take a turn unless it fulfills one of the if statements to stop the player from winning, or to make the computer win. The if statements aren't all in there, but I like to make sure everything's working before I do the stuff I know will work. Please help me
