Ctor/Dtor order

shura

Hi!

Situation:

class A
{
B m_B;
C m_C;
};

Can I assume that for all C++ compilers
the order of subobjects creation is:
m_B first then m_C.
and the order of destruction is
m_C first then m_B.

I don't think it's good to _assume_, but the order
you describe is required by the Standard. So, all
Standard-compliant compilers should do it that way.

Yes. Of course, B may have its own subobjects and so on.
