CS12 Topic list for midterm

Book: Chapters 5.1--5.5, 6--8

Classes
 declaration 
 definition (implementation)
 division into separate files
 data members -- declaration
 data members -- initialization (not in class definition)
 data members -- how to access 
 member functions -- writing
 member functions -- calling
 public & private
 the scope opertor ::
 constructor
 parameters to constructor
 default parameters
 initializer lists
 destructor
 accessor methods (return value of private data)
 mutator methods (change value of private data)
 memberwise copy with assignment
 objects as data members
 self reference to calling object (*this)
 cascading

Operator Overloading
   why do it?
   keyword operator
   which operators may be overloaded (donšt memorize all, but know examples)
   restrictions on overloading
   overloading unary operators, binary operators
   how compiler translates overloaded operator method
   how compiler translates overloaded function (not part of class)
 friend functions
 overloading the insertion (<<) and extraction (>>) operators
   as friend function
   takes ostream & as argument, returns ostream &
   one other argumemt

Pointers
 what are they (addresses of memory locations)
 declaring (must be pointer to some type)
 assigning value
   of existing variable
   of another pointer (to same type)
   of dynamically allocated memory location 
 dereferencing a pointer (with *)
 pointer arithmetic
 pointers and arrays
 accessing array elements through pointers
 using pointers to pass parameters by reference
 
Pointers and classes
 the "this" pointer (used in methods only, refers to the invoking object)
 pointers to objects
  accessing object members and functions by dereferencing (*p).x or p->x
 copying objects containing dynamic data
   where problems can occur
   overloading the = operator for copying dynamically allocated memory.


Anything else mentioned in class may show up on the test.  Review your
notes carefully.
