A recursive function

	may return a value or not
	cannot take any parameters

	must return a value if it takes parameters
	cannot return a value

When calling a function on an object pointed to by a pointer variable, we use operator

	::
	.

	->
	=

Array elements:

	may be a mix of primitive and object types
	may not be of a struct type

	may be of a struct or a class type
	may only be of a primitive type

If you do not overload any operators for a class you create

	operator ++ exists and has the default behavior
	operator < exists and has the default behavior

	operator = exists and has the default behavior
	operator + exists and has the default behavior

To assign values to a structure variable, you use the

	the = operator
	the :: operator

	the <- operator
	the -> operator

A derived class pointer can point to

	a derived class object only
	a base or a derived class object

	a derived class object or objects of its derived classes
	a base class object only

In the derived class definition, you list from the base class

	all the member functions
	only the member functions that are overriden

	only the public member functions
	all the data members and member functions

Using a data member of type Engine in Car class is an example of

	encapsulation
	IS-A relationship

	inheritance
	composition
