String Replace

How do I get my program to replace the parts of my string with whatever the user enters? For example, here I'm trying to put an x into the string pos for whatever position the user enters. The string stays in tact for the first 2 entries, but after that a number disappears. What gives?

  #include <iostream>
#include <string>

using namespace std;

int main()
{
    string pos = "012345678";
    int move;
    string letter = "x";
    for(int i = 1;i<9;i++)
    {
    cout << pos << endl;
    cout << "Your move is: ";
    cin >> move;
    if(move == 0)
    {
        pos.replace(0,1,letter);
    }
    if(move == 1)
    {
        pos.replace(1,1,letter);
    }
    if(move == 2)
    {
        pos.replace(2,2,letter);

    }
    if(move == 3)
    {
        pos.replace(3,3,letter);
    }
    if(move == 4)
    {
        pos.replace(4,4,letter);
    }
    if(move == 5)
    {
        pos.replace(5,5,letter);
    }
    if(move == 6)
    {
        pos.replace(6,6,letter);
    }
    if(move == 7)
    {
        pos.replace(7,7,letter);

    }
    if(move == 8)
    {
        pos.replace(8,8,letter);
    }
    cout << pos << endl;
    }

    return 0;
}

You just want it to replace the one number, right?

If so, the second parameter in replace should simply be 1, not the same number as move.
