I have a class called Grid that declares a vector of vectors like this:
typedef vector<int> row;
typedef vector<row> myMatrix;
myMatrix sudoku_;
The constructor looks like this:
grid::grid() : sudoku_(9,9)
{
}
As you can see, the constructor is initializing it to be a 9x9 grid. How can I make it work so that the user is asked for a number, say n, and the grid is initialized n x n ?
