问题

I wonder how to get the size of std::tr1::array<int, 16> >?

is it just 16*sizeof(int), which is how 16 byte?

回答1:

Try sizeof(std::tr1::array<int, 16> >)

回答2:

Yes, std::tr1::array is guaranteed to be an aggregate type that wraps the underlying raw array, which in fact you can access with the data() member function. And the size of a raw array is the number of elements times the size of one element.
