- 6. Course guidelines We have a common goal: It is my job to teach you what you need to know. Therefore… Ask me questions. Do NOT let me continue if you aren’t clear about something and remember that: question is the half of knowledge. If I go too fast, ask me to slow down. If I use a term that you aren’t familiar with, ask me for a definition. Attendance: is encouraged and required. 6 Presented & Prepared by: Mahmoud R. Alfarra
- 7. Course guidelines Prepare yourself: For best understanding… Study lecture one by one Respect the lecture: Any noise made during the lecture (e.g. A mobile phone ringing, a student talking to, or laughing with his or her mate, absent) will be considered impolite. Plagiarism is strictly punished: Don’t associate people’s work to yourself. Site everything you include in your reports that is not your original work. 7 Presented & Prepared by: Mahmoud R. Alfarra

- 9. A word about lectures PPT notes will be available for all lectures on my web site, BUT: You learn better when you actually have to write things down yourself. Just reading/Listening along with my notes makes you sleepy. Everything I say is NOT in the lecture notes, but anything I say MIGHT be on an exam or in a assignments, so you need to take notes on what I say In this course, you should read/do practice/ ask many times if you hope to have an excellent grade. 9 Presented & Prepared by: Mahmoud R. Alfarra

- 15. What is Data Structures ? The collection of basic data types is called data structure. 15 Presented & Prepared by: Mahmoud R. Alfarra
- 16. Classification of data structure 16 Presented & Prepared by: Mahmoud R. Alfarra Structure Non Linear Hierarchical Group Linear
- 17. Linear data structure 17 Presented & Prepared by: Mahmoud R. Alfarra Head Linked List Stack Queue
- 18. Non-linear data structure A hierarchical collection is a group of items divided into levels. An item at one level can have successor items located at the next lower level. 18 Presented & Prepared by: Mahmoud R. Alfarra
- 19. Non-linear data structure A nonlinear collection of items that are unordered is called a group. The three major categories of group collections are sets, graphs, and networks. 19 Presented & Prepared by: Mahmoud R. Alfarra
- 20. Classification of data structure 20 Presented & Prepared by: Mahmoud R. Alfarra Memory allocation Dynamic Static
- 21. Static memory allocation Static memory allocation means the program must obtain its space before the execution and can not obtain more while or after execution. Example: array data structure 21 Presented & Prepared by: Mahmoud R. Alfarra
- 22. Dynamic memory allocation The dynamic memory allocation is the ability for a program to obtain more memory space at execution time to hold new nodes and to release space no longer needed. Dynamic data structures as: Array lists Linked Lists Stacks Queues Trees 22 Presented & Prepared by: Mahmoud R. Alfarra
