Answer 1

There is no way to define a constant size vector. If you know the size at compile time, you could use C++11's std::array aggregate.

#include

If you don't have the relevant C++11 support, you could use the TR1 version:

#include 

std::tr1::array a;

or boost::array, as has been suggested in other answers.
