Problem 2:
  Deduct 0.3 for each missed type.
  Deduct 0.7 for each missed value.

Problem 5:
  Grade is max of the following two methods:
  a)  Deduct 1 point for each incorrect printed value.
  b)  Deduct 1.4 point for each incorrect value,
      but ignore incorrect values that follow from previous mistakes.

Problem 6:
  1 point for initialization of m before loop
  3 points for proper for-loop header to examine elements of array
      (1 point for each expression of the for-loop header
  2 points for correct comparison inside for loop
      (give 0.5 of 2.0 if comparing adjacent elements)
  2 points for update of m

Problem 8:
  1 point for initialization before loop
  3 points for proper for-loop header to examine elements of array
      (1 point for each expression of the for-loop header
  3 points for correct comparison and update inside with loop
  1 point for return

Problem 10:
  Generally the points were divided across the parts of the expression.
  However, if no function was used, 1.5 points were deducted.

Problem 11:
  Generally, half-credit if testing only works for one of the two cases

Problem 12:
  1 point, if the test is only for the first character (usually strcmp)

Problem 13:
  For partial credit
    1 point, if test determines position of last character (strlen)
    1 point, if test determines '!' is anywhere in the string

Problem 14:
  1.5 point, for finding first '@'
  2.5 point, for comparing following string with "cs.unca.edu"
    1.5 if comparision starts with slightly wrong string (off by one)
    1.0 if comparision starts from begining of s

Problem 15:
  -1.0 point, using "w" rather than "r"
  -0.5 point, using r rather than "r"
  -1.0 point, wrong parentheses on test
  -1.0 point, compares fopen result with value other than NULL

Problm 16:
  2.0 points -- for fopen part -- as in prob 15
  3.0 points -- for test that '?' is first character
  3.0 points -- for test EOF occurs after first character
