Botched random choice selection function

[Xom]

Good morning. I was making a tic-tac-toe program to become a little more experienced with C++, but I've come to an error I can't remove.

#include <iostream>
#include <ctime>
#include <cstdlib>
using namespace std;

int AI(int board[3][3]);
int wincon(int board[3][3]);

int board()
{
    int board[3][3]={};
    int j=1;
    int XorO;
    int *pXorO=&XorO;
    pXorO=new int;
    for (int i=0;j==1; i++)
    {
        XorO=i%2+1;
        int choice;
        if (XorO==1)
        {
        cin>>choice;
        }
        else
        {
            choice=AI(board);
            }
    switch(choice)
    {
    case 1:
                  board[0][2]=XorO;
                  break;
    case 2:
                  board[1][2]=XorO;
                  break;
    case 3:
                  board[2][2]=XorO;
                  break;
    case 4:
                  board[0][1]=XorO;
                  break;
    case 5:
                  board[1][1]=XorO;
                  break;
    case 6:
                  board[2][1]=XorO;
                  break;
    case 7:
                  board[0][0]=XorO;
                  break;
    case 8:
                  board[1][0]=XorO;
                  break;
    case 9:
                  board[2][0]=XorO;
                  break;
                  }
                  for(int j=0; j<3; j++)
                          {
                           for (int k=0; k<3; k++)
                               {
                                      cout<<board[k][j];
                                      }
                               cout<<"\n";
                               }
                               wincon(board);
                               
    }
    return 0;
}
                  
int main()
{
    cout<<"Would you like to play a game of tic-tac-toe?\n";
    cout<<"If so, please make the first move.\n";
    board();
    return 0;
}

int AI((int board)[3][3])
{   
    int reroll;
    do
    {
    int x=rand()%3;
    int y=rand()%3;
    if ((board[x][y]==1)||(board[x][y]==2))
       {
        reroll=1;
        }
    else
        {
                 reroll=0;
                 }
                 }
    While (reroll)
    return (3*x+y+1);
}

int wincon(int (&board)[3][3])
{
    for (int i = 0; i < 3; i++){
        if ((board[i][1] == board[i][2] == board[i][3])||(board[1][i] == board[2][i] == board[3][i]))
        {
                cout<<"Player "<<*pXorO<<" wins!";
                break;
        }
        else if ((board[1][1] == board[2][2] == board[3][3])||(board[1][3] == board[2][2] == board[3][1]))
        {
             cout<<"Player "<<XorO<<" wins!";
             break;
             }
             }
    return 0;
}



}

I'm confident that the error isn't in board(), since that was the first function I took care of, and it handled two-player tic-tac-toe well. Whenever I compile, I get the errors "'Int AI' redeclared as different type of symbol" on line 80, with "int AI((int board)[3][3])", and "Previous declaration of 'int AI((*)[3])'", on line 6 with the prototype of AI.

Can anyone see where I went wrong?

Just make your implementation match your prototypes.

There is no need to add any extra ()& characters.

Look at the function implementation:

int AI((int board)[3][3])

You don't need the () around the int board.

There are other errors but this is the one you asked about.

I didn't check the logic, but there are several syntax errors:
1. It is while ..not While.
2.You need a ; after the while() of a do..while
3. pXorO and XorO are local to board() , to access them in other functions, pass them by reference.
4. x and y need to be declared outside the loop first.
5. What is the last ' } ' for ?
6. Remove the () around int board in the definition.
7. Why do you have an array named board inside a function called board ?

[EDIT: Just saw some of these covered above]
