5) Show the code for an addition method for a Complex class. (You of course recall that a complex number

has both a real and an imaginary part.) (Reminder: Adding two values does not change either of the values, but

creates a third value which is the originals sum.) (Hint: There is a perfectly good call signature for such a function

such as Complex Complex::add(const Complex & b) const;)

Since you are here and thinking about it, some programmers might find it useful if Complex addition were

compatible with the built-in types double, for instance. Write such an overload here:

Q)

If a class has the following private data members:

string site; // location of sample collection

vector sample_values; // values of samples taken

Discuss/code appropriate accessors/mutators for these two members. (Thought-provokers: How many functions

would be needed for each member? Are any meta-level functions required? Do programmers outside the class

want the entire member or just a piece of it at a time?)
