Здравствуйте, Pavel XP, Вы писали:

Корректно. Инициализация членов производится в порядке их объявления в классе:

C++ Standard, 12.6.2/5
Initialization shall proceed in the following order:

• First, and only for the constructor of the most derived class as described below, virtual base classes shall be initialized in the order they appear on a depth-first left-to-right traversal of the directed acyclic graph of base classes, where “left-to-right” is the order of appearance of the base class names in the derived class base-specifier-list.
  
  
• Then, direct base classes shall be initialized in declaration order as they appear in the base-specifier-list (regardless of the order of the mem-initializers).
  
  
• Then, nonstatic data members shall be initialized in the order they were declared in the class definition (again regardless of the order of the mem-initializers).
  
  
• Finally, the body of the constructor is executed.

Вот кусок кода.

struct A
{
 ....
};


struct B
{
    B(A* a) { ...}
   .....
};


struct C
{
   C(): b(&a) { }


    A a;
    B b;
};

Вопрос: все ли здесь корректно в классе С? Вызывает сомнение очередность инициализации членов.
