Constant-sized vector

Question

Does someone know the way to define constant-sized vector?

For example, instead of defining

std::vector

it will be

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 <array>

std::array<int, 10> a;

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

#include <tr1/array>

std::tr1::array<int, 10> a;

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