1. func1(num) passes an array parameter to the function func1 while
   func2(num[9] ) passes the double num[9] to the function func2.


2. a) Class: See 6.2 of the text and the lecture notes.
   b) Object: See 6.2 of the text and the lecture notes.
   c) Structure: See 6.1 of the text and the lecture notes.
   d) Array: See 9.1 of the text and the lecture notes.

4. The following void function is taken from the lecture notes:

   void copy_numbers(ifstream& input_stream, ofstream& output_stream)
   // Copies numbers from the input_stream to the output_stream
   {
     int num;
     while (input_stream >> num)
        output_stream << num << endl;
     return;
   }


5. See pages 528-529 of the text and the lecture notes.


6. See section 6.1 and 9.1 of the text and the lecture notes. Two concrete
   differences are:
   a) An array is a collection of homogenous types whereas a structure
      may contain different types.
   b) An array is an indexed data structure. The elements are obtained by
      determining the offset from the zeroth cell. Structure elements must
      be explicitly named by way of the dot operator.
