Chapter 8:

1. Physics students:
a. Overload the + operator to add Vector objects. Each Vector object has two attributes: a magnitude; and a direction (an angle relative to the positive x-axis). The + operator should return a new Vector object and should represent the vector sum of two other Vector objects.

b. Overload the * operator to do the cross product of two vector objects given in component form. (You’ll be dealing with 3-dimensional vectors here.)

Chemistry students:
Overload the combine two Ions objects as a neutral compound. Each Ion object has an atomic symbol attribute and a charge attribute. The + operator should print the correct chemical formula. For example, if you have barium + chloride in the main, your program should print BaCl2; ammonium + sulfate yields (NH4)2SO4, including the parentheses.

2. Do chapter 8 problem #12.
