  • 8665f996e5 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(). master Reina Harrington-Affine 2025-09-19 00:00:30 +00:00
  • 848898ff11 WIP overbuilt solution to exercise 1-17. Reina Harrington-Affine 2025-09-17 20:54:19 +00:00
  • 2084b2ae84 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. Reina Harrington-Affine 2025-09-16 18:54:10 +00:00
  • df60eb6528 Reverted a change that erroneously removed ex1_17.c. Reina Harrington-Affine 2025-09-05 18:52:32 +00:00
  • 841097a626 Formatting adjustments and created initial file for exercise 1-17. Reina Harrington-Affine 2025-09-05 18:49:44 +00:00
  • 481f76699e 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. Reina Harrington-Affine 2025-09-02 21:02:47 +00:00
  • 5ec722b2ca recall() now properly closes storage.txt on completion. Reina Harrington-Affine 2025-09-02 20:35:08 +00:00
  • e57d4717d7 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. Reina Harrington-Affine 2025-09-02 20:33:31 +00:00
  • 87e93e98ca Stub of an improved version of ex1_16 to allocate array sizes on the fly and support arbitrarily long input. Reina Harrington-Affine 2025-08-28 23:32:07 +00:00
  • c47e378a4f 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. Reina Harrington-Affine 2025-08-28 21:25:07 +00:00
  • 4ddc868da3 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. Reina Harrington-Affine 2025-08-27 00:13:13 +00:00
  • 2ab16dd901 Notes added by 'git notes add' SakurajimaShida 2025-08-26 11:22:06 -07:00
  • 73d3fe21ac 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. Reina Harrington-Affine 2025-08-26 17:52:11 +00:00
  • 22694dfae0 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. Reina Harrington-Affine 2025-08-26 17:42:41 +00:00
  • cff9570b57 KNR C exercise 1-14 implementation with some really cool optimization and tricks. Reina Harrington-Affine 2025-08-23 19:49:32 +00:00
  • 207fe60c5b 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 Reina Harrington-Affine 2025-08-22 18:32:09 +00:00
  • 136abce9bf Cleaned up formatting. Removed an unused comparison in the for loop responsible for printing the histogram. Reina Harrington-Affine 2025-08-22 18:23:16 +00:00
  • 14730549f1 Push final version of ex1_13 to repo, as only the skeleton was included in the initial commit by mistake. SakurajimaShida 2025-08-21 11:52:11 -07:00
  • 296d1157a0 Completed exercise 1-13, with a bonus version that trades an extra 4 bytes in memory for an equally miniscule perfomance gain at execution. SakurajimaShida 2025-08-19 17:45:32 -07:00
  • 4b03274352 Skeleton prototype for exercise 1-13. SakurajimaShida 2025-08-19 13:58:39 -07:00
  • dbf602e13d Implemented KNR C Exercise 1-12, reusing mostly modified code from my previous (optional) implementaiton of KNR C's example wordcounting program. Reina Harrington-Affine 2025-08-16 02:14:40 +00:00
  • 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. Reina Harrington-Affine 2025-08-16 02:07:42 +00:00
  • 313e4aaa3b 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. Reina Harrington-Affine 2025-08-16 01:53:43 +00:00
  • d3ce211f14 Implemented a suggestion from Affine to replace the many if statements with a single switch and only ever call getchar at one point in the code. Reina Harrington-Affine 2025-08-14 22:32:02 +00:00
  • 43f172da21 Cleaned up unnecesary curly braces. Reina Harrington-Affine 2025-08-14 22:07:31 +00:00
  • b466a300d0 Annotation updates. Reina Harrington-Affine 2025-08-14 22:05:46 +00:00
  • 2638922bbe Untested initial version of code for visibility. Reina Harrington-Affine 2025-08-14 21:54:38 +00:00
  • 635a8300a3 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). Reina Harrington-Affine 2025-08-14 20:02:00 +00:00
  • abc0ac1660 Rewrote while loop as a for loop to reduce overall program size. Reina Harrington-Affine 2025-08-14 19:52:12 +00:00
  • d6f81778ef Completed and improved ex1_10 using a switch function. Reina Harrington-Affine 2025-08-14 19:23:28 +00:00
  • d3262419a8 Added comments to explain certain code behaviors in ex1_10.c so that they can be read and referred to later more easily. Future code should be properly annotated on initial commit. Reina Harrington-Affine 2025-08-14 17:42:15 +00:00
  • 1ac53c22b2 Minor change to reprint a single \ as \ instead of \. Reina Harrington-Affine 2025-08-14 17:29:11 +00:00
  • bbf858134c 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. Reina Harrington-Affine 2025-08-14 17:27:43 +00:00
  • 84a9263691 Added a solution of 1-9 developed collaboratively by both of us <3 Reina Harrington-Affine 2025-08-14 07:15:51 +00:00
