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

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

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.

Added ex1_10-5.c, an implementation of an example wordcount program on pages 21/22 of KNR C, purely as an exercise to see if I could do it more efficiently than the book. This resulted in a binary that was, 138 lines long as disassembled.

Implemented suggestions from affine. Considerably simplified the program by removing initialization for 'a' prior to loop entry; 'a' is now declared as the initialization expression for the loop, performing a getchar at the same time and preventing a null byte from being printed as the first character (even though this was not visible to the user).

Initial incomplete implemenation of exercise 1-10. Current version only reprints tabs to \t and backslashes to \ rather than the intended behavior of doing that in addition to reprinting backspaces as \b. Bug is due to not capturing backspaces as input. Fix pending.
