ENGR1050 C for Engineers
To begin our exploration of programming, starting with an investigation into the various data types available in C, along with their properties, and collaboratively authoring and documenting the project and its specifications.
Do note, the productive way to go about this project involves taking the following steps:
If you start too late, and do not ask questions, and do not have enough time and don't know what is going on, you are not doing the project correctly.
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.

You will want to go here to edit and fill in the various sections of the document:
Binary is a coding system that uses a combination of 0s and 1s in order to both simulate and create mathematical algorithms. The system uses 4 bits of any combination of 0 and 1 to simulate one of 256 values, ranging from 0 to 255. Each 0 correlates to a lack of value, while each one correlates to unit holding a value of a power of 2. For example, a 1 in the unit's place (i.e. 0001) is equal to a value of 2 to the power of, meaning 1. A 1 in the ten's place (i.e. 0010) is equal to 2 to the power of 1, meaning 2. A 1 in the hundred's place (i.e. 0100) equals 2 to the power of 2, meaning 4. A 1 in the thousand's place (i.e. 1000) is equal to 2 to the power of 3, meaning 8. Higher numbers are made by combining ones and zeroes in a way that the different values are added up to create a number between 0 and 255. For example, 1011 can be interpreted as 2^3 + 0 + 2^1 + 2^0, or 8 + 0 + 2 + 1, which means 1011 is the same as eleven.
Hexadecimal, aka base 16, is a way to represent numbers as a combination of 16 numbers and symbols. This allows us to describe numbers with many digits in a more concise and convenient way than base 2. In hexadecimal 1=1, 2=2, 3=3, 4=4, 5=5, 6=6, 7=7, 8=8, 9=9, A=10, B=11, C=12, D=13, E=14, and F=16. Hexadecimal numbers are proceeded by “0x” followed by a combination of the aforementioned numbers and letters. For example, if we wanted to represent the number 2024 in hex, we would write 0x7E8, which is equivalent to writing 7(16^2)+14(16^1)+8(16^0). We essentially multiply each letter or symbol value by 16 raised to the power of it's place. If we had a longer number, like 0xA61E, we could express this as 10(16^3)+6(16^2)+1(16^1)+14(16^0).
When in lab 46, you can compile by simply using “make”
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 (assuming you have a program called uom0.c):
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 to obtain project by the 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]
