To begin our exploration of programming, starting with an investigation into the various data types available in C, along with their properties.

To assist with consistency across all implementations, data files for use with this project are available on lab46 via the grabit tool. Be sure to obtain it and ensure your implementation properly works with the provided data.

lab46:~/src/SEMESTER/DESIG$ grabit DESIG PROJECT

Please study any provided code or supporting documents, and look up, experiment, and ask questions on aspects that you do not understand.

This project will be exploring the nature of some of the data types available to us in the C Programming Language. How much space is allocated to each type, and what are the ranges available for each type?

A program is provided that will display (to STDOUT) the size (in bytes), the lower and upper bounds of each studied type, and some other related information.

The data types covered for this project will include signed and unsigned variations of:

• char
• short int
• int
• long int
• long long int

The sizeof() and printf() functions, as well as arithmetic and logical operators, will be utilized in performing much of the work.

Your task is to first study and understand what the provided code is doing. It is expected you will ask questions on discord to gain clarification.

Once you have an understanding of what is going on, extend the code to support the other types (both signed and unsigned). In total, you should have TEN total sections.

You will want to go here to edit and fill in the various sections of the document:

• https://lab46.g7n.org/notes/cprog/fall2024/projects/dtr0

To be successful in this project, the following criteria (or their equivalent) must be met:

• Project must be submit on time, by the deadline.
  • Late submissions will lose 33% credit per day, with the submission window closing on the 3rd day following the deadline.
• All code must compile cleanly (no warnings or errors)
  • Compile with the -Wall and --std=gnu18 compiler flags
  • all requested functionality must conform to stated requirements (either on this document or in a comment banner in source code files themselves).
• Executed programs must display in a manner similar to provided output
  • output formatted, where applicable, must match that of project requirements
• Processing must be correct based on input given and output requested
• Output, if applicable, must be correct based on values input
• Code must be nicely and consistently indented
• Code must be consistently written, to strive for readability from having a consistent style throughout
• Code must be commented
  • Any “to be implemented” comments MUST be removed
    • these “to be implemented” comments, if still present at evaluation time, will result in points being deducted.
    • Sufficient comments explaining the point of provided logic MUST be present
• No global variables (without instructor approval), no goto statements, no calling of main()!
• Track/version the source code in your lab46 semester repository
• Submit a copy of your source code to me using the submit tool (make submit on lab46 will do this) by the deadline.

Let's say you have completed work on the project, and are ready to submit, you would do the following:

lab46:~/src/SEMESTER/DESIG/PROJECT$ make submit

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.

I'll be evaluating the project based on the following criteria:

52:dtr0:final tally of results (52/52)
*:dtr0:used grabit for project by Sunday prior to duedate [13/13]
*:dtr0:clean compile, no compiler messages [13/13]
*:dtr0:program conforms to project specifications [13/13]
*:dtr0:code tracked in lab46 semester repo [13/13]

NOTE: spirit of the project includes using hexadecimal values and bitwise logic operators to set the pertinent upper/lower bounds.

• each class member is to participate in the contribution of relevant information and formatting of the documentation
  • minimal member contributions consist of:
    • near the class average edits (a value of at least four productive edits)
    • near the average class content change average (a value of at least 256 bytes (absolute value of data content change))
    • near the class total content contribution average (a value of at least 1kiB)
    • no zero-sum commits: no adding in one commit then later removing in its entirety for the sake of satisfying edit requirements
  • adding and formatting data in an organized fashion, aiming to create an informative and readable document that anyone in the class can reference
  • content contributions will be factored into a documentation coefficient, a value multiplied against your actual project submission to influence the end result:
    • no contributions, co-efficient is 0.50
    • less than minimum contributions is 0.75
    • met minimum contribution threshold is 1.00

• Solutions not abiding by spirit of project will be subject to a 50% 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 or otherwise maintaining consistency in code style and presentation will be subject to a 25% overall deduction
• Solutions not organized and easy to read (assume a terminal at least 90 characters wide, 40 characters tall) are subject to a 25% overall deduction
