It seems that mutator and accessor functions defeat the purpose of making the member variables private. Why is this not so?
What will be an ideal response?
The mutator functions can filter data and control the way data members are set. For
example, you (as class author) can exclude illegal data. With accessor functions you
(as class author) can allow the client to see just the variables you want seen, in the
format in which you want them seen.
