Suppose a data member of a class is to be given an initial value. We have a function that clients can use for setting the initial value called setValue. For this particular data member, after the setValue function has been used once, there is no reason to use it again. Clients have been using this class for a while, but later on we realize that we could have just made a constructor that sets the initial value, saving the client from having to use a call to the setValue function. We should:
A. add the new constructor and take the setValue function out B. leave the class the way it is, to avoid client confusion C. add the new constructor and leave the setValue function in D. send an email of apology to the clients
