Course Outline Attendance andQuiz Policy: •Attendance in class is mandatory. •Inadequate attendance (less than 85%) may lead to disqualification from the Midterm and/or Final Exams. •Take attendance on random days. •There could be both announced and un- announced quizzes •Deadlines are hard deadlines.
- 6. Course Outline Academic Honest: •Whatis plagiarism? “Plagiarism is defined as presenting someone else’s work as your own. Work means any intellectual output, and typically includes text, data, images, sound or performance.” (Office of Academic Appeals & Regulation 2005) Office of Academic Appeals & Regulation, 2005, Section 2.1 of the published procedures on “ Cheating, plagiarism and fraudulent or fabricated coursework ” (available online at http://www.leeds.ac.uk/AAandR/cpff.htm - accessed 6th Aug 2005)
- 7. Course Outline Plagiarism isserious: •All cases are reported and go on your student record. •Penalties vary from written warnings, re- sitting modules to expulsion from the University. •Why? – plagiarism undermines the University’s reputation and the quality of its degrees and research, plus plagiarists miss out on learning!
- 8. Course Outline Plagiarism Detection: •Subjectexperts knowledge of the discipline and its literature. •Changes in writing style, inappropriate writing style. •Electronically.
- 9. Course Outline References: •“Write thetext taken from others in double quotes and italicize the text. Put referencec at the end.”[1]. •If your ideas match to someone put references [2]. •If you want to put multiple references. Put them like it [3][4][5][6]. •You have to double quote the major terms like “Software Engineering”.

- 11. Good programmers canrule the kingdom ! 11
- 12. Understanding Computer Componentsand Operations 12 Hardware and software: the two major components of any computer system Hardware: equipment, or devices Software: programs that contain instructions for the computer Four major operations in a computer: Input Processing Output Storage
- 13. Program Input (Data) PROGRAM Output (Results) (Algorithm) 13 Takes some values as INPUT PROCESS Them Produce some result as OUTPUT
- 14. Programming Task 14 A typical programming task can be divided into two phases: Problem solving phase produce an ordered sequence of steps that describe solution of problem this sequence of steps is called an algorithm Implementation phase implement the program in some programming language
- 15. Understanding Computer Componentsand Operations 15 Input devices: allow data to enter the computer Mouse, keyboard, scanner Processing: working on the data Organizing data Checking data for accuracy Mathematical or other manipulations on data Central Processing Unit (CPU): hardware that performs the tasks
- 16. Understanding Computer 16 Components and Operations Output devices: provide data to the user Printer, monitor, speakers Programming language: special language containing instructions for the computer Visual Basic, Java, C#, C++, COBOL Syntax: rules governing word usage and punctuation in the language
- 17. Understanding Computer 17 Components and Operations Machine language: controls the computer’s on/off circuitry Compiler or interpreter: software that translates programming languages to machine language Program must be free of syntax errors to be run, or executed, on a computer To function properly, the logic must be correct Algorithm = Syntax + Semantics
- 18. Understanding 18 the Programming Process Six programming phases: Understand the problem Plan the logic Code the program Use software to translate the program to machine language Test the program Put the program into production
- 19. Understanding the Problem 19 May be the most difficult phase Users may not be able to articulate their needs well User needs may be changing frequently Programmers may have to learn the user’s functional job tasks Failure to understand the problem is the major cause of most project failures
- 20. Planning the Logic 20 Plan the steps that the program will take Use tools such as flowcharts and pseudocode Flowchart: a pictorial representation of the logic steps Pseudocode: Natural language representation of the logic Walk through the logic before coding by desk- checking the logic
- 21. Pseudo Code andFlow Charts 21 Pseudo Code Algorithms written in structural English Good way to begin a solution design Program flow is not always clear Flow Charts Graphical representation Express flow of control
- 22. Using Software toTranslate the Program into Machine Language 22 Creating an executable program
- 23. Points to Note: 23 1. The process consists of repeated application of simple steps 2. All steps are unambiguous (clearly defined) 3. We are capable of doing all those steps 4. Only a limited no. of steps needs to be taken 5. Once all those steps are taken according to the prescribed sequence, the required result will be found 6. Moreover, the process will stop at that point

- 38. What is aflowchart? Flowcharts are one method for creating an Algorithm. They allow a process to be described in a step-by-step manner. Other Algorithm types are Pseudocode and Prose.
- 39. Terminators Start Oval Shape One line in or out Used to indicate the beginning and end of a process Stop
- 40. Data Boxes Parallelogram shaped Input One line in, One line out Used to indicate the input or output of data from the system. Output
- 41. Process Boxes Rectangle shaped One line in, One line out Used to indicate a process step Process
- 42. Decision Boxes Diamond shaped One line in, two lines out Must contain a binary Yes/No question (Yes/No, Question True/False, 0/1, etc) Used to branch a program dependent upon a condition being met
- 43. Subprocess Box Rectangle shaped, with bars on the sides One line in, One line out Subprocess Used to include a predefined process
- 44. Bad design… What is wrong with this chart? The box has two lines in, one line out… Lines must join other lines, never boxes!
- 45. Bad design… What is wrong with this flowchart? Never use curved lines. Always straight Always vertical or horizontal.
- 46. Remember… Drawing flowcharts is actually easy. Breaking tasks into small steps is often much harder than it might seem. If you can flowchart it, you can program it.
