Hi I have a

struct People { const char* fname_; const char* lname_; unsigned int id; }

I want to create an array of 3 people.

boost::array<People, 3> = { {"Chun", "Wang", 1441}, {"Chia", "Wang", 1443}, {"Ta", "Wang", 1445} };

I get a compile time error too many initializer.

Use an added level of brace enclosing: {{ {"Chun", "Wang", 1441}, {"Chia", "Wang", 1443}, {"Ta", "Wang", 1445} }}; See http://boost.org/doc/html/array/rationale.html for more details.

Thanks. It's quite clear to me now. Max LoadCom <LoadCom <at> sina.com> writes:

boost::array<T,N> is an agregate class (which means you can initialize it with a brace-enclosed list) containing a member T elems[N]; which is in turn an aggregate. So, if you've got a boost::array<People,3>, the list { {"Chun", "Wang", 1441}, ... } is apt to initialize elems, and for initializing the boost::array you've got to add another level of {}: {{ {"Chun", "Wang", 1441}, ... }} although the standard allows the omission of the outer level under some circumnstances, as noted in http://boost.org/doc/html/array/rationale.html Hope it's clearer now.
