Dependencies in Initialization Lists

Question

Is this behavior well-defined?

class Foo
{
    int A, B;

    public:

    Foo(int Bar): B(Bar), A(B + 123)
    {
    }
};

int main()
{
    Foo MyFoo(0);
    re         


        

Answer 1

Initialization is done in the order of appearance in the declaration, not the order you write it in the constructor.

Look at this question, it's somewhat similar: Initializer list *argument* evaluation order
