initialization list order

I have an initialization list:

Code:

---

class foo : a(), b(), c() {

---

For some reason I get a warning "c will be initialized after b". Why?

That order probably differs from the order in which they are declared in the class and which determines the real order how class members are going to be initialized.

This could lead to errors if you use members of the class to initialize other members.

Code:

---

struct X
{
    int b;
    int a;
    X(int n): a(n), b(a) {} //a will be initialized after b which uses a's value!
};

Yep! Thanks again!

Just missed this one, I take it?
