(ARM, §12.1, §12.8) The compiler does not generate a copy constructor or a default operator= for a simple class. A simple class is a class that:

• Is a base class or is derived only from simple classes
• Has no class members or has only simple class members
• Has no virtual member functions
• Has no virtual base classes
• Has no constructor or destructor
Constructors:

---

class Simple { int f; };

void simpleFunc (Simple s1)
{
  Simple s2 = Simple(s1); // ERROR: An explicit copy constructor 
                          // call. The compiler generates no 
                          // default copy constructor.

  Simple s3 = s1;  // OK: The compiler performs a bitwise copy
}
