vector of vectors

[Magos]

It tried using a vector of vectors, but for some reason it woouldn't compile. Can't remember the error, something about a missing comma I think.

std::vector<std::vector<int>> MyVec;

Either I'm making some stupid obvious mistake, or it's not possible this way.

On a side-related note, I used a typedef and it compiled fine:

typedef std::vector<int> vec_int;
std::vector<vec_int> MyVec;

Why is the first not valid?

You need to put a space between those last '>' otherwise it's seen as the '>>' operator, ie:

std::vector<std::vector<int> > MyVec;

*Ouch*
Yeah, that makes sense.
Thanks!
