Don't think of it as an object."anything" is a C struct, not a class. So 
you use like a C struct. This line will fail to compile:

---
anything a;
---

because there's no type "anything". But there IS a type "struct 
anything", so you can use:

---
struct anything a;
---

to create a variable of this type ("struct anything"). If you don't want 
to write "struct anything", you have to declare your struct like this:

---
typedef struct
{
  int a;
  int b;
}anything;
---

Now you can just write "anything a;", as "anything" is now a new type.

My recomendation: try not to mix C and C++ when you are learning one of 
them; learn them as independent languages (if you learned C++ first, 
don't skip the C introduction, or you will only get confused about the 
details; the same applies to learning C first and then C++).
