== Catalog Description ==

This course is a continuation of CS 201. It involves a deeper study of programming languages, but emphasizes programming in a particular language. Topics include algorithm design and analysis, data structures, recursion, threads, network programming, graphics, security, and ethics.  Prerequisites - C or better in CS 201.

== Prerequisites ==
* basic programming concepts 
* ability to use unix

== Standard Content ==
===Course Outline ===
* Review (2 weeks)
** C Programming - all keywords and operations, libraries and header files
** Data formats and number systems (binary, decimal, octal, hex), signed/unsigned, two’s complement, floating point, long, int, short char, C strings
** I/O with different data formats and number systems
** Basic data structures - unsorted array, sorted array, linked list, heap, stack, queue - code for all in class and as assignments
** Search and sorting - linear and binary search, selection and insertion sort, mergesort, heapsort, quicksort - code for all in class and as assignments
* Asymptotic analysis and running time (1 week) - big O/Omega/Theta, little o/omega, definitions, basic proofs, polynomials / exponentials / logarithms, recursion trees
* Memory organization (1 week) - text, data, heap, stack, malloc, free, pointer arithmetic
* Unix and debugging (1 week) - gdb, grep, sed, awk, find, compiler options, makefiles, unix regular expressions, reading manual and manual organization, pipes, I/O redirection
* Disk organization (1 week) - inodes, superblocks, etc.
* New data structures (4 weeks) - binary search tree (including balanced), hash table, skip list, trie, B tree - code for some in class and as assignments
* Graphs (1 week) - terminology, adjacency matrix, adjacency list, basic algorithms (BFS, DFS, shortest path, minimum spanning tree) - do all algorithms on the board, code for some in class, running time for all
* Classes and objects in C++ (2 weeks) - data abstraction and encapsulation, defining classes, creating objects, inheritance, protection, virtual functions and polymorphism
* The Standard Template Library (1 week)
* Comparison of C++ and other OO Languages (Java, Python, etc.) (1 week)

===Learning Outcomes===
* C programming and debugging, 
* data structures understanding (can explain lookup/insert/delete for each DS, work small examples on paper, know running times) and 
* coding (can finish partially complete DS code, write new functions to traverse DS)


===Important Assignments and/or Exam Questions===
* Programming assessment - must pass with 3 and 2 halves to get a C or better
* Data structures programming, exam/homework question - given prototype for insert/lookup/delete, can give correct code
* Data structures programming, exam/homework question - given prototype for function that should use data structure functions, can give correct code
* C programming play computer, exam question - given any short C program (a few dozen lines, say) and sample input, can trace execution and final output
* Some large project that is interesting - game, etc.
