Just need a function for my prog

[futureProgrammer]

Hello everyone, i'm new to programming in C++ and i am trying to make tic-tac-toe with the basic knowledge i have. I have proceed this much.

#include <iostream>
using namespace std;
main()
{
    int a,b,c,d,f;
    cout<<"1,1|1,2|1,3\n";
    cout<<"___|___|___\n";
    cout<<"2,1|2,2|2,3\n";
    cout<<"___|___|__\n";
    cout<<"3,1|3,2|3,3\n";
    cout<<"   |   |  \n";
 
    system ("pause");
 
    system ("cls");
 
    cout<<" X |   |\n";
    cout<<"___|___|___\n";
    cout<<"   |   |\n";
    cout<<"___|___|__\n";
    cout<<"   |   |\n";
    cout<<"   |   |  \n";
 
    cout<<"Make Your Move";
    cout<<"a";
    cin>>a;
    cout<<"b";
    cin>>b;
 
 
    if(a==2&&b==2)
    {
 
    }
 
    else 
    {
        if (a==2 && b!=2)
        {
            c=1;
            d=3;
        }
        else 
 
            if (a!=3 && c!=1)
        {
            c=3;
            d=1;
        }
        else 
        {
 
            c=1;
            d=3;
        }
    }
 
    system ("cls");
 
 
 
 
 
}
 

The logic behind this coding is not understandable, as i haven't written any comments, but its perfectly alright. All i need now is a function or command which can set my cursor in the tic-tac-toe box above. Means its like that if user inputs the value (like 1,1 for top left box, 2,2 for middle one, like in the above figure) i'll calculate that vaue with some procedure and will store that in a,b. Now all i'm looking for is such type of function which could set the cursor on value of 'a' and 'b'. eg if user inputs 1,2, then the cursor should be automatically set to that position 1,2 and print O. something like this. i just want to save my coding space, don't want to make boxes again and again and print that value in it.
Any idea or hint plz?

The TicTacToe (search also "Noughts and Crosses") issue has been tackled quite often here....

the simplest solution (and I know it isn't actually what you asked) would be to redraw your board after every move, that is , rather than try to change what is on the screen, just create a new board to show the current state of play.

Moving the cursor position is not standard c++. On linux, you can use ncurses. On windows, some sort of call to the windows API should do the trick. I would just re-draw the board.

But wouldn't redrawing the board would increase the length of my Programme? Actually i have to sumbit this assignment and i don't want it to look awful lengthy.
Maybe i have to try this one if i don't find any other way out.
