Course materials

An excellent pledge on how to be a student in a course (CS @ U. of Virginia)

last year's course

  1. Introduction
    Sample program: use of conditional
  2. Recursion
    Sample programs: box fractal, different variants for sum of series
  3. Characters. Assignment. Iteration
    Sample programs: prefix expression, filtering HTML text
  4. Iteration. Side effects
    Sample program: prefix to postfix expression
  5. Number representation. Bitwise operators
    Sample programs: bitwise add, reverse hex digits, playing with bitmaps, split float
  6. Arrays
  7. Input/Output
    Sample programs: ints line by line, simple string search, URL search
  8. Review: counting change, n choose k, replace chars, balanced parantheses, adding floats. Also see this summary
  9. Pointers
    Sample programs: numbers from string, sort string array
  10. Dynamic allocation
    Sample programs: read whole text, with limited lines; generic array minimum
  11. File I/O
    Sample programs: check segment lengths in PDF files: v.1 v.2, bitmap size, stream bits
    continued from class: hide a file in a BMP image and extract it
  12. Structures
    Sample programs: float with bitfields, function term
  13. Modular compilation. Abstract datatypes. Integer lists: intlist.h, intlist.c
    more list functions, header file, sample program. work with linked lists
    queues: header, implementation, test program
  14. Hashing. Timing. Randomization. Hashtable: header, implementation, test program

If you're at a computer without a C compiler, you can compile/run code online, e.g., at JDoodle.
