Map with string key and wstring[] value

[campesr]

Hi!

I'd like to have a map with string keys, and wstring[] (arrays) values
in c++.

I thought map<string, wstring[]> would work out, but it doesn't (at
least I think so).

Additionally I'd like to know what's the easiest way to populate such
a map.

Would - mymap["somekey"] = {L"My Unicode value one", L"My other
unicode value"}; - work?

Many thanks in advance.

You can't do that. The stored value has to satisfy certain requirements
(be copy-constructible and assignable), and arrays don't.

No. The closest you can get to what you want is to have

std::map<string, std::vector<wstring> >

.

Thanks.

I suggest to try a deque because it offers better or equally good time
complexity for all operations:

map<string, deque<wstring> >

Hi!

Except that std::deque does not have the same property that may be
important to the OP -- the data are not stored contiguously.

Yes, right. I should have mentioned it. I'm sorry.

OK. Many thanks to all of you.
