  0. Take a look at the sample exam posted  on  the  webpage. 
     Expect some questions on arrays.

  1. [3 points] State all important properties of an algorithm.

  2. [2 points] What type of statement does all computational  work  for
  any programming language?

  3. [3 points] Why do we need comments in a program?  Describe two ways
  of writing comments in a C program and the difference between them.

  4. [2 points] What is the default name of an executable file generated
  by gcc (the C compiler) on sparky?

  5. [3 points] What is the difference between a  logical  error  and  a
  syntax error?

  6. [3 points] Convert the switch statement example in class notes that
  deals with section-numbers, to an if-else chain.

  7. [5 points] Write a program that reads in two integers m and n, both
  >  0,  and  calculates  m  raised  to the power n in a variable called
  power. Print power at the end. (power = m*m*m* ... *m  n times).

  8. [6 points] Q5 on page 118 of the text.  What is the output  of  the
  given program?

  9. [8 points] Study program 7.3 given on page 103 of the text.  Now do
  problem  6  on  page  118.  Remember  you  are going to print first 15
  Fibonacci numbers without using an array. You  need  three  variables.
  Print  numbers  as  soon as they are generated. You need to initialize
  the first two numbers to 0 and 1 respectively. Do not forget to  print
  these before the loop.

  10. Expect something on Functions.
