Using C++ .....
You should start by downloading the tictactoe_final.cpp program:

This program is finished but the computer player is not very strategic and relies only on random guesses to determine the next move:
} }
}
First, rewrite the above code so that the determination of the next computer move is done in a separate function. After the rewrite the above code should look like:
Next, make the determination of a move in the new generateComputerMove() function more strategic (Hint: you can add rules instead of always just determining a random move).
Explanation / Answer
here is the simple code to do that -
#include <iostream>
#include<cstdlib>
using namespace std;
int checkwin( char[]);
void board( char[]);
int main()
{
char square[10] = {'o','1','2','3','4','5','6','7','8','9'};
int player = 1,i,choice;
char mark;
do
{
board(square);
if(player%2==1)
player=1;
else
player=2;
// player 2
if(player==2)
{
cout << "Players " << player<<endl;
cout<<"Press Enter for CPU"<<endl;
choice=rand()%9;
mark='O';
int turn=1;
int placed=0;
while(placed==0)
{
if (choice == 1 && square[1] == '1'){
