Rewrite appropriate programs from earlier chapters and exercises with pointers
instead of array indexing. Good possibilities include getline (Chapters 1 and 4),
atoi, itoa, and their variants (Chapters 2, 3, and 4), reverse (Chapter 3), and
strindex and getop (Chapter 4).

/* This problem does not have a well-defined goal so I don't feel especially motivated
* to do it. I feel I have a good grasp of pointers and so these exercises seem like
* rather menial translation of previously solved problems. I have a good grasp of
* pointers so I will skip this and carry on with subsequent exercises. */
