How to do the vector of sets in C++?

Question

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!

Answer 1

Instead of '>>' try '> >'... like so:

vector<set<char> > testVect;

Answer 2

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.
