Initializing 2D Vector?

Hi forum!

I wonder how can I a initialize a 255x255 Square Matrix ?

I thought that Using a Vector should be the easy approach, but how can I initialize them?


I have:

Code:

---

Vector < Vector <int> > matrix2d; //this should be initialized as 255x255 2D vector

---

and offcourse when I do something like matrix[j][i] = 123;
I get a EXEC_BAD_ADDRESS!.

Any help is very appreciated!

thanks.

It should be something like this:

Code:

---

std::vector<std::vector<int> > matrix2d(255, std::vector<int>(255));

---

Thanks!,
That was fast
