Course Update Information 

Course Objectives

This course teaches the basic techniques to orgranize data in running programs.  You will know about well-known data structures as listed in the Quick Syllabus. You will be able to
(1) implement these structures as classes in C++;
(2) determine which structures are appropriate in various situations;
(3) confidently learn new structures beyond what are presented in this class. 
You will also learn part of object-oriented programming and software development methodology.
Quick Syllabus
To become a Data Structures Expert 
start by learning...
  • Precondition/Postcondition specifications 
  • Time analysis techniques 
  • Container classes 
  • Pointers and dynamic arrays 
  • Linked lists 
  • Templates and iterators 
  • Stacks 
  • Queues 
  • Recursive thinking 
  • Trees 
  • Sorting and searching techniques
  •  Graphs
  • Textbook and References

    Textbook: Data Structures and Other Objects Using C++,  Third Edition, by Michael Main and Walter Savitch , Addison Wesley, softcover.

    Supplements:  The Code for the Book and the Corrections for the Text will be useful and may be found by clicking here.


    CSc103 (Introduction to Computing to CS and CpE Majors) and CSc104 (Discrete Mathematical Structure I).  You should feel confident in your ability to design and implement simple programs using arrays and functions.  You should be familiar with some programming environment--either a PC or a Linux system.

    Assignments and Grading

    See syllabus above for the tentative timetable for a schedule. There will be six to seven programming assignments distributed roughly every two weeks (counted roughly 30% of your final grade).  Several in-class small quizzes will add up to 10 % of your final grade. There will be three in-class exams (60% of your final grade). Dates of these exams will be determined in due times and announced beforehand.

    Policies:  Students may discuss ideas together. But since each student get credits for his or her submissions, all actual program code and written answers must be done individually by each student, and must not be shared.

    Communications: I would like the course to run smoothly and enjoyably. Feel free to let me know what you find good and interesting about the course. Let me know as soon as possible about the reverse. You may see me in my office during my hours or send me messages by e-mail.

    Computing Facilities

    The language used for this class is ANSI Standard C++ as supported by today's available compilers. Variety of PC based (both Windows and Linux) C++ compilers are available, also publicly accessible at our Student Computer Labs.
