Homework

1. Background: A Java, C or C++ programmer could create a table of the squares of the integers from 0 to 8 by writing:

           int squares[]={0,1,4,9,16,25,36,49,64};
   

   Assume that integers are 32-bit values and assume that this table is a constant -- that is, that there will be no assignments to squares or to any of the table entries other than this initializer.

   The problem: Write SMAL code equivalent to this. (1 point)

2. Background: Consider maintaining the table of squares as a list, where each item in the list consists of a pointer to the next item in the list and an integer value. The last item in the list has a null pointer in its next tiem field.

   The problem: Write SMAL code to represent a constant list of the first four squares, in ascending order, starting with the square of zero. (1 point)

3. Background: Consider making an array of days of the week. A C programmer could write

           const char dayname[][]={ "Sunday", "Monday", "Tuesday",
                   "Wednesday", "Thursday", "Friday", "Saturday" };
   

   This is actually a constant array of pointers to null-terminated strings, despite the fact that the declaration looks like a two-dimensional array of characters.

   The problem: Write SMAL code to represent this. (1 point)
