Array Game

I did post my code earlier. But this time, im stucked at doing X O X O.
1#include <iostream>

#include <fstream> //input output text file

void new_board();
void rules();
void menu();
int main()
{
char input;
int answer;
cout << endl;
menu();
/*int choices = 0;
choices = menu();
switch(choices)
{
case 1:
{
system("cls");
new_board();
break;
}
case 2:
{
system("cls");
rules();
break;
}
case 3:
{
system("cls");
cout <<"You've chose to quit the game. See you later!" << endl;
exit(1);
}
default:
{
system("cls");
cout <<"Invalid selection"<< endl;
exit(1);
}
}*/
cin >> answer;
if (answer == 1) // new game
{
system("cls" );
new_board();
}
else if (answer == 2) // rules
{
system("cls" );
rules();
system("pause" );

Something like this?
1#include <iostream>
using namespace std;
char board[10][10];
void printBoard()
{
for (int j=0; j<10; j++)
{
for (int i=0; i<10; i++)
{
cout << board[i][j];
}
cout << endl;
}
}
void initializeBoard()
{
for (int j=0; j<10; j++)
{
for (int i=0; i<10; i++)
{
board[i][j] = '.' ;
}
}
}
void inputX()
{
int row = 0;
int col = 0;
cout << "enter row coordinate 0 to 9: " ;
cin >> row;
cout << "enter col coordinate 0 to 9: " ;
cin >> col;
board[row][col]='X' ;
}
int main()
{
initializeBoard();
printBoard();
inputX();
printBoard();
return 0;
}

Yes that's correct.. So if i duplicate it and make it to 'O'.. will that restart back the game?

I don't know what you mean by restart the game.
Usually a board game loops until some win/lose/draw state is reached or the user enters some exit value. Maybe something like this,
1int exitValue;
exitValue = testState();
while (exitValue == 0)
{
....
exitValue = testState();
}
Perhaps you should try writing the tic tac toe game first to get the idea as Othello is complex and would require code to flip the tokens after each move if required.
One technique is to use +1 for one player and -1 for the other player.
1#include <iostream>
using namespace std;
char board[8][8];
int player = 1;
int count = 0;
void printBoard()
{
for (int j=0; j<8; j++)
{
cout << j << " " ;
for (int i=0; i<8; i++) // columns
{
cout << board[i][j] << " " ;
}
cout << endl;
}
cout << " 0 1 2 3 4 5 6 7" << endl;
}
void initializeBoard()
{
for (int j=0; j<8; j++)
{
for (int i=0; i<8; i++)
{
board[i][j] = '.' ;
}
}
}
void makeMove()
{
int row = 0;
int col = 0;
cout << "enter row coordinate 0 to 7: " ;
cin >> row;
cout << "enter col coordinate 0 to 7: " ;
cin >> col;
if (player==1)
{
board[col][row]='X' ;
}
else
{
board[col][row]='O' ;
}
}
int main()
{
initializeBoard();
printBoard();
do
{
makeMove();
printBoard();
player = -player; // swap players
count = count + 1; // count moves
}while (count < 5); // make 5 moves then exit
return 0;
}

Here is a program that plays rand tic tac toe games:
1#include <cstdlib>
#include <iostream>
#include <stdlib.h> /* srand, rand */ #include <time.h> /* time */ using namespace std;
int b[9];
// int result;
int j;

// test for win position
// 3 horizontal wins
int TestWin(int t)
{
int win;
win = 0;
if (b[0]== t && b[1]== t && b[2]== t) {
win = t;
}
if (b[3]== t && b[4]== t && b[5]== t) {
win = t;
}
if (b[6]== t && b[7]== t && b[8]== t) {
win = t;
}
// 3 vertical wins
if (b[0]== t && b[3]== t && b[6]== t) {
win = t;
}
if (b[1]== t && b[4]== t && b[7]== t) {
win = t;
}
if (b[2]== t && b[5]== t && b[8]== t) {
win = t;
}
// cross wins
if (b[0]== t && b[4]== t && b[8]== t) {
win = t;
}
if (b[2]== t && b[4]== t && b[6]== t) {
win = t;
}
return win;
}
void InitializeBoard()

}

// display board

cout << " x |" ;

cout << endl;
cout << "+---+---+---+" << endl;
}
cout << endl;
}
int getBoardState()

int PlayAGame()

int result = 0; // 1 = x win , 2 = y win and 3 = draw
InitializeBoard();
DisplayBoard();
while (result == 0)
{

DisplayBoard();
}
if (result == 0 && gamesCount == 5)
{

}
cout << getBoardState() << endl;
