I can do a simple array of sets:
set < char > * words = new set < char > [10]
How I can do a vector of sets?
This results in a compiler error:
vector < set< char >> v .
Thank you for answers!

1Repeating the title in the question is not recommended and it is a poorly ask question. Add details, code you have tried, examples you have seen, what you are trying to accomplish etc. – Joe Apr 08 '11 at 19:03

Please explain what you're trying to do and what you mean by `dynamic array of sets`. – Alexander Gessler Apr 08 '11 at 19:03

`vector
> arrSets;` This will create a dynamic array (`vector`) of sets. Is that what you are asking? – Naveen Apr 08 '11 at 19:09 -
@Naveen: He'd probably want vector< shared_ptr< set< T > > > to avoid copying sets around needlessly. – Jollymorphic Apr 08 '11 at 19:14

1(They did the sets) They did the vec-tor of sets! (They did the sets) It was pure programming sex! – Potatoswatter Apr 08 '11 at 19:29

`vector < set< char >> v` doesn't work because the compiler treats the `>>` as the right shift operator. Put a space between the two `>` like so: `vector < set< char > > v`. – Emile Cormier Apr 08 '11 at 19:34

2Isn't it obvious that he's wondering why the `>>` is causing an error? I fixed the wording a bit. Seems like a legitimate question to me. Voting to re-open. – Emile Cormier Apr 08 '11 at 19:39

… also because OP added the example code shortly *after* it was closed. – Potatoswatter Apr 08 '11 at 20:05

If vector < set< char >> v is exactly what you've got there (I hope you cut and pasted), you've run into one of the annoying little features of C++.
Those >> look to you like two closing angle brackets for two templates. They look like a right shift operator to the compiler. Change them to > > with a space in between.
Fortunately, this is being addressed in the C++ standard that should be ratified this year. Unfortunately, you aren't working with a C++11-compliant compiler just now.
