1. Which of the following best characterizes what happens when a program
   attempts to invoke a function that is defined in another module but
   for which no prototype definition is supplied: (suppose main.c
   invokes function adder() in adder.c and the compile command is:
   gcc -g main.c adder.c)

   a. it will cause a syntax error      b. it will cause an error at link
      at compile time because the          time because the linker won't
      function name is not defined         be able to find adder()

   c. it will always work fine          d. it will only work if adder()
                                           returns int and its parameters
                                           are of the correct type

2. In the design proposed last class for the ray tracer

   a. structures of type sphere_t       b. structures of type obj_t
      were linked via a pointer            were linked via a pointer
      called "next".                       called "next"

   c. the pointer "next" was used to    d. the pointer "next" was used
      point from obj_t to sphere_t         to point from sphere_t to obj_t

3. Suppose "funptr" is a properly declared pointer to functions
   having two int parameters and returning int.  The correct way
   to cause it to point to "adder" is:

   a.  funptr = adder;                  b. funptr = &adder;

   c.  *funptr = adder;                 d. funptr = adder();

4. After the pointer is correctly initialized, the proper way to
   invoke the function adder through the pointer is:

   a. s = funptr(3, 4);                 b. s = (*funptr(3, 4));

   c. s = (*funptr)(3, 4);              d. s = *(funptr)(3,4);


5. Which of the following is the best approximation of the actual
   score of the Clemson FSU game saturday.  The objective function
   to be minimized is:

   | pred(clem) - actual(clem)| + |pred(fsu) - actual(fsu)|

   a. Clemson 45                        b.  Clemson 14
      FSU     14                            FSU 10

   c. FSU     17                        d.  FSU 38
      Clemson  6                            Clemson 6
