struct work_type
{
   int w[1024 * 1024];
};
struct work_type work;
struct work_type *pwork = &work;

1. Which of the following function calls will cause 4MB of data to be
   copied onto the stack:

   a. fun1(pwork);                   b. fun2(work);

   c. both                           d. neither

2. Which of the following function class will allow the called function
   to modify the caller's copy of the structure.

   a. fun1(pwork);                   b. fun2(work);

   c. both                           d. neither

3. Which best defines the way "const" works here:

   void fun1(const struct work_type *q)
   {

   }

   a. It is like a comment but has   b. It will cause a compile time
      no real effect                    error if the function contains:
                                            q->w[0] = 100;
                                        but other backdoor approaches
   c. It makes it completely             can still be used to modify the
      impossible for fun1 to            structure
      make any change to the structure


4. Consider these two function prototypes

   (1) struct work_type  fun3(void);
   (2) struct work_type *fun4(void);

   Which return from the function will cause 4MB to be copied

   a. fun3()                         b. fun4()

   c. both                           d. neither

5. Passing a large array (which is NOT embedded in a structure
   to a function can causes the array to be copied onto the stack

   a. always                         b. never

   c. it depends on whether the
      array is passed using the
      name &array[0] or just
      using the name array
