A String Class question

Hey all,

I'm probably missing something obvious, but why the HELL does this copy constructer work?

Code:

---

class StrType {
  char *p;
  int size;
public:
        StrType(const StrType &o); // copy constructor
        ~StrType()                { delete [] p; }
};

---

That's the class, here's the code:

Code:

---

StrType::StrType(const StrType &o)
{
  size = o.size;

    p = new char[size];

  strcpy(p, o.p);
}

---

Now howcome the copy constructer above can access those private members of 'o'?

Thanks.

Because the copy constructor is a member function of the same class of that of 'o'

Because o is a StrType object. It has class scope in StrType. As long as its accessed within the class, its fine.

so any member function of class X can always access any and all private members of the same class type?

Yes.

cool, thanks.
