how-to initialize 'const std::vector<T>' like a c array

c++, stl

Solution

For C++11:

vector<int> luggage_combo = { 1, 2, 3, 4, 5 };

Original answer:

You would either have to wait for C++0x or use something like Boost.Assign to do that.

e.g.:

#include <boost/assign/std/vector.hpp>
using namespace boost::assign; // bring 'operator+=()' into scope

vector<int> v;
v += 1,2,3,4,5;

Problem

Is there an elegant way to create and initialize a `const std::vector<const T>` like `const T a[] = { ... }` to a fixed (and small) number of values? I need to call a function frequently which expects a `vector<T>`, but these values will never change in my case. In principle I thought of something like ``` namespace { const std::vector<const T> v(??); } ``` since v won't be used outside of this compilation unit.
