Vector question

Hello, I have created a vector of pointers.
If I resize my vector, will it be filled in with NULL values?
Or will it point to garbage? If it will point to garbage, how do I init them on NULL?

Code:

---


vector< vector< Tile*> > board;

board.resize(size);

for (int i = 0; i < size; i++)
    board[i].resize(size);

---

This does not work because I am pointing to the values:

Code:

---


    for(int i =0; i < size; i++)
    {
        for(int j=0; j < size; j++)
        {
            board[i][j] = NULL;
        }
    }

---

Thank you

You could try using the push_back() method, and I know that int vectors are set to default value of 0, so maybe?

You should be supplying the other argument to resize()

board[i].resize(size, NULL);

I believe that if you resize a vector, all of the values will be default-constructed, so that would mean NULL, yes.
However, whiteflags has a point. You shouldn't be using resize anyway, unless you have a very specific requirement. Use push_back, and if possible, don't use pointers.
