• I reserve the rightto change thisdistribution
  during the course after notification
• The final grades arecomputed accordingto the
  following rules

11
Policies on incomplete grades and late assignments

• Turn in assignments on or before the due date and
  time
• What if the campus network is down?
• An assignment turned in up to 24-hours late will
  be reduced by 10 of the assignments worth, more
  than 24 hours late will be reduced 100
• The due date and time for each assignment will be
  specified on assignment postings
• All assignments are to be turned in through
  Blackboard (https//login.umassonline.net/lowell.c
  fm)

12
Policies on absences and scheduling makeup work

• Make-up exams will only be given in case of
  serious need and only when the instructor is
  notified prior to the exam time. If this is not
  done, the grade is automatically zero for that
  exam
• Written verification for the students inability
  to take an exam will be required
• The make-up exams will be different from those
  given to the class

13
Academic Integrity

• Finish assignments individually and independently
  except notified. Should two or more students turn
  in substantially the same solution or program, in
  the judgment of the instructor, the assignment
  will be given a grade of zero. A second such
  incident will result in an F grade for the course
• All forms of academic dishonesty will result in
  an F for the course and notification of the
  Academic Dishonesty Committee

  students with disabilities as defined by the
  Rehabilitation Act of 1973 and the Americans with
  Disabilities Act of 1990. A qualified person with
  a disability means an individual with a
  disability who, with or without reasonable
  modifications to rules, policies, or practices,
  the removal of architectural, communication or
  transportation barriers, or the provision of
  auxiliary aids and services, meets the essential
  eligibility requirements for the receipt of
  services or the participation in programs or
  activities provided by a public entity.
• Questions concerning services for people with
  learning and physical disabilities should be
  directed to

A Survey (No Credit)

1. What are the values of a and b?
2. What is polymorphism?

main() int a0, b ba printf(ad
bd, a, b)
17
Polymorphism

• One of the key features of derived classes is
  that a pointer to a derived class is
  type-compatible with a pointer to its base class
• Polymorphism is the art of taking advantage of
  this simple but powerful and versatile feature,
  that brings Object Oriented Methodologies to its
  full potential

18
Example

1. // pointers to base class
2. include ltiostreamgt
3. using namespace std
4. class CPolygon
5. protected
6. int width, height
7. public
8. void set_values (int a, int b) widtha
   heightb
9. virtual int area () 0
11. class CRectangle public CPolygon
12. public
13. int area ()
14. return (width height)

19

1. class CTriangle public CPolygon
2. public
3. int area ()
4. return (width height / 2)
6. int main ()
7. CRectangle rect
8. CTriangle trgl
9. rect.set_values (4,5)
10. trgl.set_values (4,5)
11. CPolygon ppoly rect
12. cout ltlt ppoly-gtarea() ltlt endl
13. ppoly trgl
14. cout ltlt ppoly-gtarea() ltlt endl

namespace

• Namespaces allow to group entities like classes,
  objects and functions under a name. This way the
  global scope can be divided in "sub-scopes", each
  one with its own name.
• The format of namespaces is
• namespace identifier
• entities
• Where identifier is any valid identifier and
  entities is the set of classes, objects and
  functions that are included within the namespace.
  For example

21
Example

1. // namespaces
2. include ltiostreamgt
3. using namespace std
4. namespace first
6. int var 5
8. namespace second
10. double var 3.1416
12. int main ()
13. cout ltlt firstvar ltlt endl
14. cout ltlt secondvar ltlt endl
15. return 0

22
Example using namespace

1. // namespaces
2. include ltiostreamgt
3. using namespace std
4. namespace first
6. int var 5
8. namespace second
10. double var 3.1416
12. int main ()
13. cout ltlt firstvar ltlt endl
14. cout ltlt secondvar ltlt endl
15. return 0
