1. The modification to the function that was suggested last time
   for mapping pixel to world coordinates was:

    a. world_x = world_size_x * win_x  /  (win_size_x + 1)

    b. world_x = world_size_x * win_x  /  (win_size_x - 1)

    c. world_x = (win_size_x + 1) * win_x  /  (world_size_x)

    d. world_x = world_size_x * (win_size_x - 1) / win_x


2. The elements of a table of attribute types declared as
   shown are:

   static char *ac_attrs[] =
   {
      "position",       /* Current location of aircraft */
      "direction",      /* Direction of travel          */
      "speed",          /* Speed in NM/hr               */
   };

   a. character strings       b. ints

   c. character variables     d. pointers to characters strings


3. The proper way to define the number of entries in a
   table such as this one is:

   a. #define NUM_ATTRS  (sizeof(ac_attrs) / sizeof(char))

   b. #define NUM_ATTRS  (sizeof(ac_attrs[0]) / sizeof(char *))

   c. #define NUM_ATTRS  (sizeof(ac_attrs[0]) / sizeof(char))

   d. #define NUM_ATTRS  (sizeof(ac_attrs) / sizeof(char *))


4. In the model description language we described in class a
   set of attribute values may be followed by:

   a. }                      b. an attribute type

   c. a or b                 d. end-of-file

5. In the model description language described in class, end-of-file
   can legally follow what token(s)?

   a. {                                b. }

   c. a collection of attribute        d. any of the above
      values
