These are possible exams questions to go along with project 3 if/when
I reuse it in a future semester (I did not use these during 05F).


The correspond to common mistakes folks made when completing project3.

(1) strtok in the wrong order

  Give some code with the strtok's in the wrong order.
  Show that the code doesn't work (i.e. show the wrong output,
   or the segfault, or whatever).

  Ask what needs to be done to fix it.

  (e.g. how should the code be re-written to be correct?)

(2) atoi vs. atof

  Same format of question as (1)

(3) count vs. numTrails vs. MAX_HIKING_TRAILS

  Student confused the numTrails or count variable which keeps track of
  how many elements of the array were actually "in use" vs. the 
  #define MAX_HIKING_TRAILS which keeps track of the total size of the
  array.

  Also, they would be confused between the name of the formal parameter
  numTrails, and the variable count (which they would copy from some 
  sample code).  Getting the error "count not defined", they would
  declare it as a local variable (uninitialized) and get incorrect
  output.

  Same format of question as (1).
