Lab Assignments Hands-on experience will be gained through programming projects that cover the course material. Design documents are required for all the problems given. Design Document: The basic items in the design document will include: Problem Definition Requirement Specifications Solution Strategy S/W Design for the whole problem: Structured (Top-Down) Design in the form of modules (C++ functions) in which each module is associated with a given subproblem. Prof. Amr Goneid, AUC

22
**Lab Assignments S/W Design for Each Module:**

Functional Specifications: the purpose of the module and what it is supposed to do (What to do) Data Specifications: the data resources needed by the module to achieve it functionality (with what) Precondition: the state of processing or data before the module is executed (state before) Postcondition: the state of processing or data after the module is executed (state after) Algorithm Specification: the algorithm or methodology used by the module (How to do it) Prof. Amr Goneid, AUC

23
**Coursework Grading 30% Programming Assignments.**

5 % Quizzes, class participation and attendance 20% Midterm Exam (1) 20% Midterm Exam (2) 25% Final Exam Prof. Amr Goneid, AUC

24
Course Outcomes After completing the CSCE 210, students should be able to: Demonstrate knowledge and understanding of Data Models, Data Abstraction and ADTs and their role in problem solving and S/W development. Choose the appropriate data structure for modeling a given problem. Design and implement various ADTs in a high level language (C++) using Object Oriented Concepts. Topics include Linked lists, Simple Containers (Stacks, Queues), Dictionaries (Key Tables and Lists, Binary Search Trees, Hash tables), Priority Queues and Heaps, Disjoint Sets and Graphs. Prof. Amr Goneid, AUC

25
Course Outcomes Compare alternative implementations of data structures with respect to performance. Demonstrate experience in the design of algorithms for solving problem that use the above data structures. Demonstrate knowledge of common applications for each data structure in the topic list. Practice basic algorithm analysis using complexity bounds (Big-Oh, Big-Theta and Big-Omega). Applications include Quadratic Sorting methods and Divide & Conquer recursive sorting (n log n) examples (Merge Sort and Quick Sort). Prof. Amr Goneid, AUC
