    ok heres the scenario. This is my code in a function that copies a 2-d vector into a new 2-d vector:
    1) n is a private class variable that holds the size of the grid of the class object (The size is actually n squared).
    2) grid1 is a 2d vector class variable that holds the grid itself of the class object. It is defined in the form of vector <vector<int> > grid1;

    The following is a code for a copy constructor that passes "grid2" as a parameter, which is the 2d vector to be copied.
    ---------------------------------
    n=grid2.n();
    vector<int> ss(n^2);

    for(int i=0;i<(n^2);i++){
    grid1.push_back(ss);
    }

    for(i=0;i<(n^2);i++){

    for(int j=0;j<(n^2);j++){


    grid1[j] = grid2[j];
    }

    }


    I am getting the following error:

    ...\Sudoku.cpp(33): error C2676: binary '[' : 'const Sudoku' does not define this operator or a conversion to a type acceptable to the predefined operator

    Do you really want n ^ 2 or do you want n * n?
