C++ member variable initializaton order

Question

can you tell me in which order the member variables of an object are initialized (constructor calls) and if the initialization list has an influence on it? For example if I instantiate:

 class Meta
 {

 public:
    Meta() : a(), b(),c(),d()
    {

    }

 private:

    SomeObject d;
    SomeObject c;
    SomeObject b;
    SomeObject a;
 };

Would the member variables be initialized in the order a,b,c,d ( as in the initialization list) or d,c,b,a (the order in which they are defined in the class) ? I'm experimenting with Visual Studio 2012 Debugger and my tests suggest the latter, but I'd like to know if I can influence it via the initialization list.

Regards

They're done in the order they're declared in, irrespective of the initializer list.
