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.
Begin Declare v of vector type. Call push_back() function to insert values into vector v. Print “Vector elements:”. for (int a : v) print all the elements of variable a.
A vector, once declared, has all its values initialized to zero.
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;
