问题
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!
回答1:
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.

Instead of '>>' try '> >'... like so:
vector<set<char> > testVect;
