vector of vectors

[zergmuncher]

I'm making a program which is a guitar chord calculator, to do this, I need to make a vector of vectors, (we use a class called apvector, so don't get like...confused). How do I declare this? Right now, I have:

apvector<apvector<int> jerry(5)> harry(5);

and it won't work. Any idea? if it's my apvector include file, where can I get the vector include file...and how do I call the function (IE cout<< harry[3].jerry[2] or something like that? Ok, it's the end of the period, I have to go.

i'm not much help, but here's one my friend programmed in flash =)

try:

apvector<apvector<int> > harry(5);

can I have the inner vector have a name? Or would that require a struct? And how do I call it? Either harry[3][2] or
harry[3].jerry[2] (<-- note the dot). And I'll check out the flash one, thanks, all you guys!!:rock:

It's a standard class, just #include <vector>

can I have the inner vector have a name?

Nope, it's a template argument.

Or would that require a struct?

If you want it to have a name, indeed you'll need a struct with just one member (the vector<int> named jerry). Harry would then be a vector of those structs.

And how do I call it? Either harry[3][2]

That's the one. Don't forget to allocate enough space in your inner vectors as well:

apvector<apvector<int> > Harry (5);

Harry[0].resize (20);
Harry[1].resize (12);
(etc.)

wow, guys, thank you so much. I really appreciate that.:p
