2015-01-30	Solve Exercise 5-18: error-recovering `dcl`	zlg	1	-0/+172
	This exercise was a real pain in the ass. The original use of getch() and ungetch() was inferior to a line-based approach. It really doesn't seem like the way a parser should be built, but it taught me a little about the order of recursion. I'm convinced that a debugger is necessary if you want to build a good parser. This implementation doesn't recurse in a natural way, or even enough to stack data type prefixes. Hopefully by the time I get to 5-20 I'll have enough ideas to implement something that does recurse well.

2014-03-20	Solve Exercise 5-14: reverse sort	zlg	1	-0/+152

2013-10-18	Solve Exercise 5-13: tail	zlg	1	-0/+106
	This exercise was somewhat irritating until I caved and used the code in section 5.6 like the exercise suggested. The solution is not what I think is clean, but given that [mc]*alloc haven't been covered yet, it's probably the best one can muster. Once I used the code in §5.6, the program fell into place. Still, it was a neat exercise.
2013-10-13	Solve Exercise 5-12: flexible `detab` and `entab`	zlg	2	-0/+157

2013-09-26	Solve Exercise 5-11: `entab` and `detab` remixed!	zlg	2	-0/+137
	This one was pretty rough. At first I wanted to include a bunch of error-catching and "smart" stuff. When I took a second look at it and realized `itoa` returns 0 on a string, things became a bit easier. I may have been able to outsource a few things to a function or two, but overall I think it worked out.
2013-09-24	Clean up 5-10's printf() calls	zlg	1	-4/+0

2013-09-24	Solve Exercise 5-10: expr	zlg	1	-0/+107

2013-09-21	Solve Exercise 5-9: day of year functions with pointers	zlg	1	-0/+74
	This exercise was fun and taught me a bit about initializing arrays and working with pointers.
2013-09-15	Solve Exercise 5-8: Checking for errors	zlg	1	-0/+83

2013-09-11	Solve Exercise 5-7: Improved readlines()	zlg	1	-0/+106

2013-09-08	Solve Exercise 5-6: pointer-based functions	zlg	1	-0/+154
	This exercise was not very fun or interesting. While I somewhat enjoyed learning to use pointers, this was a bunch of busywork. It felt like homework, and that's terrible. It's the first exercise I've outright disliked. If you're writing a programming book, don't make exercises like this one!
2013-09-03	Solve Exercise 5-5: strn{cpy\|cat\|cmp}	zlg	1	-0/+76
	This exercise seemed like it was designed to "pull it all together" with things learned in the previous few pages. Not much new in terms of techniques, but more a test to see how you could blend everything together.
2013-09-02	Solve Exercise 5-4: strend()	zlg	1	-0/+37
	Detailed answers below the question will only occur now if I cannot explain myself well enough in code and nearby comments. I'm looking to learn how to write better comments so there's less need for prose.

2013-08-19	Solve Exercise 5-2: getfloat()	zlg	1	-0/+75
