Programming Assignments that do not execute will not be
accepted!
Tests are scheduled for 90 minute lab periods on Tuesdays.
Tests consist of a closed book part and an on-line open-book
programming part.
One-Time Test Retake Option: May re-do an in-class test as a
take home. Test grade will be averaged with in-class grade or
80% whichever is smaller. One time only offer!

Course Mechanics (cont.)
Labs: Attendance is mandatory; 10 points deducted for missing a
lab w/o a legitimate excuse (if contacted ahead of time)
Academic Integrity: work must be your own; assistance may not
be given or received; all programming assignments are
pledged; zero for test or programming assignment + report
made to Honor Council
Class Attendance Policy: 20 point bonus if no more than 3
unexcused absences and no labs missed
For each class I will hand out copies of the notes!
Copies can be found on web-site if you miss class – but don’t
Bring your textbook to class!
Expectations are that you will have done the reading before coming to
class; you are responsible for Review Questions at the end of each
chapter

Classroom Behavior
1.
switch off cell phones – no texting in class
2.
No “surfing” the internet – stay focused on the class
2.
Please do not get up in the middle of class to visit the water fountain
or rest room
Individual Named Work Folders for assignments can be found on
Q:\Computer Science\Classes\Comp150Fa16 Shelburne
Use a flash drive or create H:\Comp150 folder for your work
(Here’s the Small Print)
Comp 150: Computer Programming I is a course in which a
certain amount of material must be and will be covered.
Reducing the amount of material covered is not an option.

Your learning in this course is important to me. I invite you
to talk with me about ways to ensure your full participation
in this course. Please be aware that Wittenberg is
committed to providing reasonable accommodations for
students with documented disabilities. If you are eligible for
course accommodations because of a disability, you need to
register with the Academic Services Office, COMPASS Center
located in Thomas Library. After you register, give me your
accommodation letter from Academic Services and arrange
to talk with me about your learning needs privately in a
timely manner. Early identification at the start of the term is
essential to ensure timely provision of services. If you have
questions or would like more information about services for
students with disabilities, please contact Grace Whiteley,

Computer Science is the study of algorithms, including
Their formal and mathematical properties
Their hardware realizations
Their linguistic realizations
Their applications
N. Gibbs and A. Tucker. "A Model Curriculum for a Liberal Arts Degree in Computer
Science"; CACM 29, No 3 (March 1986)
Definition of Algorithm (after Al Kho-war-iz-mi a 9th century
Persian mathematician) - an ordered sequence of unambiguous
and well-defined instructions that performs some task and halts
in finite time
This will be a question on the first test
The 3 gallon – 5 gallon jug problem
Given a five gallon jug and a three gallon jug, can you
determine a way (algorithm) to measure out exactly four
gallons?
Note: You cannot estimate quantities; for example filling
both the 5 gallon jug and the 3 gallon jug half way to give
you a total of 4 gallons is not a solution
5 Gal.
3 Gal.

A computer is an (electronic) device operating under the control
of instruction stored in its own memory (stored program
concept) that
1. Accepts data (input)
2. Processes the data arithmetically and logically
3. Produces output (information) from the processing and/or
4. Stores the results for future use
Why Comp 150 is a great and useful liberal arts course
1. The “Gold Standard” of Computer Literacy is the ability to
program a computer
2. Computer Technology Dominates our Society
3. It’s all about Problem Solving.
4. It’s Creative! You get to Build Things in Software!
