| - | ====Submission Criteria==== | ||
| - | To be successful in this project, the following criteria must be met: | ||
| - | |||
| - | * Project must be submit on time, by the posted deadline. | ||
| - | * Early submissions will earn 1 bonus point per full day in advance of the deadline. | ||
| - | * Bonus eligibility requires an honest attempt at performing the project (no blank efforts accepted) | ||
| - | * Late submissions will lose 25% credit per day, with the submission window closing on the 4th day following the deadline. | ||
| - | * To clarify: if a project is due on Wednesday (before its end), it would then be 25% off on Thursday, 50% off on Friday, 75% off on Saturday, and worth 0% once it becomes Sunday. | ||
| - | * Certain projects may not have a late grace period, and the due date is the absolute end of things. | ||
| - | * all requested functionality must conform to stated requirements (either on this project page or in comment banner in source code files themselves). | ||
| - | * code resulting in two binaries must be submitted: | ||
| - | * source code that when compiled produces the **encode** program | ||
| - | * if you're only using one file for the encode, that source file should be called **encode.c** | ||
| - | * source code that when compiled produces the **decode** program | ||
| - | * if you're only using one file for the decode, that source file should be called **decode.c** | ||
| - | * Output generated must conform to any provided requirements and specifications (be it in syntax or sample output) | ||
| - | * output obviously must also be correct based on input. | ||
| - | * Processing must be correct based on input given and output requested | ||
| - | * Specification details are NOT to be altered. This project will be evaluated according to the specifications laid out in this document. | ||
| - | * Code must compile cleanly. | ||
| - | * Each source file must compile cleanly (worth 3 total points): | ||
| - | * 3/3: no compiler warnings, notes or errors. | ||
| - | * 2/3: one of warning or note present during compile | ||
| - | * 1/3: two of warning or note present during compile | ||
| - | * 0/3: compiler errors present (code doesn' | ||
| - | * Code must be nicely and consistently indented (you may use the **indent** tool) | ||
| - | * You are free to use your own coding style, but you must be **consistent** | ||
| - | * Avoid unnecessary blank lines (some are good for readability, | ||
| - | * Indentation will be rated on the following scale (worth 3 total points): | ||
| - | * 3/3: Aesthetically pleasing, pristine indentation, | ||
| - | * 2/3: Mostly consistent indentation, | ||
| - | * 1/3: Some indentation issues, difficult to read | ||
| - | * 0/3: Lack of consistent indentation (didn' | ||
| - | * Code must be commented | ||
| - | * Commenting will be rated on the following scale (worth 4 total points): | ||
| - | * 4/4: Not only aesthetically pleasing, but also adequately explains the WHY behind what you are doing | ||
| - | * 3/4: Aesthetically pleasing (comments aligned or generally not distracting), | ||
| - | * 2/4: Mostly consistent, some distractions or gaps in comments (not explaining important things) | ||
| - | * 1/4: Light commenting effort, not much time or energy appears to have been put in. | ||
| - | * 0/4: No original comments | ||
| - | * should I deserve nice things, my terminal is usually 90 characters wide. So if you'd like to format your code not to exceed 90 character wide terminals (and avoid line wrapping comments), at least as reasonably as possible, those are two sure-fire ways of making a good impression on me with respect to code presentation and comments. | ||
| - | * Sufficient comments explaining the point of provided logic **MUST** be present | ||
| - | * Code must be appropriately modified | ||
| - | * Appropriate modifications will be rated on the following scale (worth 3 total points): | ||
| - | * 3/3: Complete attention to detail, original-looking implementation | ||
| - | * 2/3: Lacking some details (like variable initializations), | ||
| - | * 1/3: Incomplete implementation (typically lacking some obvious details/ | ||
| - | * 0/3: Incomplete implementation to the point of non-functionality (or was not started at all) | ||
| - | * Implementation must be accurate with respect to the spirit/ | ||
| - | * 3/3: Implementation is in line with spirit of project | ||
| - | * 2/3: Some avoidance/ | ||
| - | * 1/3: Generally avoiding the spirit of the project (new, different things, resorting to old and familiar, despite it being against the directions) | ||
| - | * 0/3: entirely avoiding. | ||
| - | * Error checking must be adequately and appropriately performed, according to the following scale (worth 3 total points): | ||
| - | * 3/3: Full and proper error checking performed for all reasonable cases, including queries for external resources and data. | ||
| - | * 2/3: Enough error checking performed to pass basic project requirements and work for most operational cases. | ||
| - | * 1/3: Minimal error checking, code is fragile (code may not work in full accordance with project requirements) | ||
| - | * 0/3: No error checking (code likely does not work in accordance with project requirements) | ||
| - | * Track/ | ||
| - | * Submit a copy of your source code to me using the **submit** tool (**make submit** will do this) by the deadline. | ||
