CSCS1320 C/C++ Programming
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:
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:
Within dtr0.c you will find multiple sections, commented respective to their task. You will write very similar code for the required sections, each section meant for a different data type in C (and titled appropriately). As an example of the code you'll need, all the tasks for signed char have already been completed. It is your job to study the given code and implement it elsewhere in the program where appropriate to create sections for each data type, which will be formatted and printed to the terminal.
These sections will contain multiple print statements to display information and formatting. They will also contain some computations for determining some of the information that will be printed to the screen. For example, take the following statement:
quantity = (long double) pow (2, (size * 8));
This statement informs us of the possible distinct values, which we will need for our output.
To get an idea of what your output should look like for each section, you can compile and run the program before even making any modifications. Notice that there is formatting to align the information in the right “column”. There are seven values paired with their respective textual descriptions to the left. Some of these values are dynamic and computed by our code, and some of these values are static or hard-coded.
To be successful in this project, the following criteria (or their equivalent) must be met:
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.
