Good work - but *please* don't fall into the trap of comments that
just describe what the code does. You need to assume that most people
who look at the code can read it pretty well. Concentrate on
commenting that which is non-obvious.
Yes, 'non-obvious' is subjective. But
size_t sl = strlen(somestring); /* get length of string */
would be bad :)
