I am looking for the code that enables me to do the following with Boost.Array:

boost::array<unsigned int,16> tmp = { { 4, 4, 4, 4, 3, 3, 3, 3, 2, 2, 2, 2, 1, 1, 1, 1 } };

I would like to learn how to do this. I have need to easily initialize a 4x4 grid with data.

boost array does nothign special. Any class which is defined as a POD type (Plain Old Data) supports aggregate construction.
To make a POD class, all memeber should be POD and public, dont inherit from anything and dont provide constructor.

POD != aggregate. An aggregate class is a class with no user-declared constructors, no private or protected non-static data members, no base classes, and no virtual functions.

The following type is an aggregate but isn't a POD.

struct a

{

std::string s;

};

Also, all arrays are aggregates.
