At long, panful last, a functional version of exercise 1-17. The code has contracted considerably since the intiially architected version, with replicate() and its functionality having been eliminated as unnecessary, saving numerous cycles and ~64kB of memory, advance() has been eliminated due to creating needless complexity, hindering readability, and decreasing efficiency, and recall has been eliminated because it depended on replicate, and was also unnecessary as enumerate() now contains three lines of code that completely eliminate the need for replicate() or enumerate().

WIP version of ex1-17-2.c that crashes during a memory safety check in store() for some reason. If I comment out the check, it spins and segfaults. Cause unknown.

storage.txt is now created at runtime rather than being assumed to be present and empty. recall() now removes storage.txt at completion. main() now includes a check to see whether storage.txt already exists, sends an error message, and exits with code 1 if storage.txt is already present.

WIP solution to exercise 1-16 using a file on disk as a storage buffer for stdin so that we can step through the input repeatedly.

Stub of an improved version of ex1_16 to allocate array sizes on the fly and support arbitrarily long input.

Skeleton of exercise 1-16; functionally a verbatim copy of the example text on page 30 of KNR C, though in reality, I have made it more readable and fixed a couple of bugs related to expanded functionality of modern C.

An implementation of exercise 1-15 that I spent far too long banging my head against over an issue that turned out to be me having flipped 5 and 9 in my math.

Fixed a potential bug that would cause a hang on unrecognized input. Added a 39th position to both charCount and printTable for storing, enumerating, and displaying untracked characters that do not fit to a defined position in charCount.

Added support for numbers. Removed refTable[], changed enumeration loop to check via sequential if-else statements if a character is within a given range. This was done in favor of a lookup array to improve performance.

Per suggestions and feedback from Affine, removed a loop that initialized the charCount array, since modern C allows us better ways to do this. Saved 5 instructions in the binary :3

Cleaned up formatting. Removed an unused comparison in the for loop responsible for printing the histogram.

Push final version of ex1_13 to repo, as only the skeleton was included in the initial commit by mistake.

Completed exercise 1-13, with a bonus version that trades an extra 4 bytes in memory for an equally miniscule perfomance gain at execution.

Implemented KNR C Exercise 1-12, reusing mostly modified code from my previous (optional) implementaiton of KNR C's example wordcounting program.
2523043172
Nearly direct copy of a word count program from KNR C, mimicked here only so that I could compare the size of the resulting binary once compiled to my own solution, archived as ex1_10-5.c (ex1-10.5). The resulting binary, as compiled with GCC, was 136 lines long, 2 lines shorter than my own. Challenge failed :sigh:. Good exercise, though; I'll come back to this and study why later.
