Corning Community College CSCS1730 UNIX/Linux Fundamentals ======Project: LETTER DIVISION GENERATOR (ldg0)====== =====Objective===== Write a wrapper script around a long division generator in order to create a functional letter division generator in the pctX style. =====Abstraction===== {{page>haas:fall2023:common:projects:abstraction&noheader}} =====Locational Awareness===== {{page>haas:fall2023:common:projects:location&noheader}} =====Reading===== Please be sure to familiarize yourself with the pertinent content in: * [[https://lab46.g7n.org/_media/haas/ufbm.pdf|UNIX for the Beginning Mage (PDF)]] * Harley Hahn's Guide to UNIX and Linux * [[/_media/haas/printf.pdf|printf PDF]] * pertinent command manual pages Please familiarize yourself with the table of contents and or index of the various resources, and sample various content to connect yourself with deeper understanding into the concepts being called upon in the current activity. =====Specifications===== Your program should: * have valid, descriptive variable names of length //no shorter than// 4 symbols * perform any needed checks to make sure needed things exist and are valid before proceeding * have consistent, well-defined indentation (no less than 4 spaces per level of indentation) * all code within the same scope aligned to its indentation level * have proximal comments explaining your rationale and what is going on, throughout your code * perform the intended operation, outputting the correct/accurate information in indicated format * at the end of your main() function, use a single return statement to conclude your code, return a 0 indicating successful operation =====Grabbing project resources===== To obtain project data, you will need to satisfy the following prerequisites: * be logged into lab46 (shell) as your user * have your semester lab46 repo cloned (into ~/src/SEMESTER) * have created the appropriate DESIG (like "cprog" or "unix") subdirectory therein (~/src/SEMESTER/DESIG) * have changed into that ~/src/SEMESTER/DESIG directory If all those conditions are met, you can use the **grabit** tool to obtain the project, as follows: lab46:~/src/SEMESTER/DESIG$ grabit DESIG ldg0 make: Entering directory '/var/public/SEMESTER/DESIG/ldg0' '/var/public/SEMESTER/DESIG/ldg0/Makefile' -> '/home/USER/src/SEMESTER/DESIG/ldg0/Makefile' '/var/public/SEMESTER/DESIG/ldg0/README' -> '/home/USER/src/SEMESTER/DESIG/ldg0/README' '/var/public/SEMESTER/DESIG/ldg0/ldg0.sh' -> '/home/USER/src/SEMESTER/DESIG/ldg0/ldg0.sh' '/var/public/SEMESTER/DESIG/ldg0/ref_ldg0.aarch64' -> '/home/USER/src/SEMESTER/DESIG/ldg0/ref_ldg0.aarch64' '/var/public/SEMESTER/DESIG/ldg0/ref_ldg0.armv7l' -> '/home/USER/src/SEMESTER/DESIG/ldg0/ref_ldg0.armv7l' '/var/public/SEMESTER/DESIG/ldg0/ref_ldg0.x86_64' -> '/home/USER/src/SEMESTER/DESIG/ldg0/ref_ldg0.x86_64' make: Leaving directory '/var/public/SEMESTER/DESIG/ldg0' lab46:~/src/SEMESTER/DESIG$ At which point you can change into the newly created and populated **ldg0** directory. ====Raspberry Pi command-line via SSH/MOSH==== If you don't have a monitor, you likely are logging into your pi remotely (doable, and good intra-system practice) Once your **ldg0** project files are 'hg' **add**ed to your repository on lab46, **commit** and **push**. On your pi, to obtain those files there, be sure to be in your repository, and 'hg' **pull** and **update**. NOTE: To avoid repository conflicts, ALWAYS check for any incoming pull/update transactions before doing a commit/push. Problems occur when you forget (this is an issue on both lab46 and your pi). Run your script: lab46:~/src/SEMESTER/DESIG/ldg0$ ./ldg0.sh =====Submission===== To successfully complete this project, the following criteria must be met: * Code must compile cleanly (no notes, warnings, nor errors) * Output must be correct, and match the form given in the sample output above. * Code must be nicely and consistently indented * Code must be well commented * Do NOT double space your code. Group like statements together. * Output Formatting (including spacing) of program must conform to the provided output (see above). * Track/version the source code in a repository * Submit a copy of your source code to me using the **submit** tool. To submit this program to me using the **submit** tool, run the following command at your lab46 prompt: lab46:~/src/SEMESTER/DESIG/ldg0$ make submit Project backup process commencing Taking snapshot of current project (ldg0) ... OK Compressing snapshot of ldg0 project archive ... OK Setting secure permissions on ldg0 archive ... OK Project backup process complete Submitting DESIG project "ldg0": -> ../ldg0-DATESTAMP-HOUR.tar.gz(OK) SUCCESSFULLY SUBMITTED lab46:~/src/SEMESTER/DESIG/ldg0$ You should get some sort of confirmation indicating successful submission if all went according to plan. If not, check for typos and or locational mismatches. What I'll be looking for: 104:ldg0:final tally of results (104/104) *:ldg0:obtained via grabit by Sunday before deadline [13/13] *:ldg0:script runs with no errors [13/13] *:ldg0:script performs stated task/algorithm [13/13] *:ldg0:script output conforms to formatting expectations [26/26] *:ldg0:script conforms to project specifications [26/26] *:ldg0:runtime tests of submitted script succeed [13/13] Additionally: * Solutions not abiding by **SPIRIT** of project will be subject to a 25% overall deduction * Solutions not utilizing descriptive why and how **COMMENTS** will be subject to a 25% overall deduction * Solutions not utilizing **INDENTATION** to promote scope and clarity will be subject to a 25% overall deduction * Solutions lacking **ORGANIZATION** ior are not easy to read (within 90 char width) are subject to a 25% overall deduction
