ACS130 Introduction to Systems Engineering and Software
Individual C Programming Assignment 1
Assignment weighting: 10% of module mark
Assignment released: Friday 23 October (Semester 1, Week 4)
Assignment due: 11.59pm Monday 9 November (Semester 1, Week 7).
How to submit
The assignment must be submitted to Blackboard by 11.59pm Monday 9 November, at the
link ACS130 > Assessment > C Programming ACS130-001. You must upload you *.c file.
There is a separate drop box for ACSE and Aero students so please submit to the correct drop
box. Mac users please make sure you submit your .c file and nothing else. If, when I
download your program from Blackboard I cannot run the file because it is not a .c file
(or for any other reason), you will NOT be marked.
Marking
I will mark your program. The attached mark sheet provides a guide to the areas on which
feedback will be provided. The rubric on Blackboard also provides a guide to the marks for
this assignment. Mac users, you need to make sure that your program runs on a Windows
environment (I do not own a Mac).
How you should work
This is an individual assignment, and it must be wholly your own work. You should not
discuss a solution to this assignment with anyone else, and you should not work with anyone
else to produce a solution. I will check for collusion and plagiarism.
You must complete this assignment in your own time, NOT in ACS130 lab sessions.
Learning outcomes
In doing this assignment, you will demonstrate your ability to program in C to manipulate files,
output to the screen, implement the selection and repetition constructs, and manipulate
variables, as well as use functions.
Assignment briefing
Write a C program to:
? Read characters (no spaces but a combination of numbers, letters and symbols) all
on the same line from the keyboard and write the characters (one at a time) to the
file File1.txt (all on the same line), then close the file.
? Read the characters from the file “File1.txt” that you have just created. (Hint: read
the characters one at a time), at the same time printing only the number characters
to the screen
? Print the count of how many numbers there are and also print the sum of these
numbers.
? In a function float mean(float sum, float N)where sum is the sum of the numbers
entered, and N is the total number of numbers.
o calculate the mean of the numbers
o return this mean to main
? Print to the screen the mean (to 2 d.p.) of the numbers from main.
? You need to program defensively and check to see if the file exists.
For example, your program should look like this when input sf98375hf^%839*&% is used:
Figure 1: Example output of code.
Please note:
1. The only library you may include is stdio.h, therefore you will not be allowed to use
pre-defined functions from any other library. You will get 0 if you use more
functions defined in other libraries (eg atoi() since this is defined in the stdlib.h
library).
2. You may not use arrays or stings (which will be covered in at the end of semester
1). You will get 0 if you use arrays or strings.
3. You may not use global variables. These are variables declared outside main. You
will get 0 if you use global variables.
4. When your program is marked, I will type in a range of characters to test your
program. You should test your program thoroughly before you submit it.
5. Your program must have meaningful comments, including a header comment, and
be well-laid out and readable.
6. Helpful tip 1: You need to think about how you’re going to check for the end of line
character.
7. Helpful tip 2: You need to think about how you’re going to convert the numerical
characters into numbers in order to be able to find the sum. Use the ASCI table (see
www.ascii-code.com) and refer to details given verbally in the lecture. You are not
allowed to use the function int atoi() because this is in the stdlib.h library.
Marking Scheme for Software
Marking Criterion Mark
Does the code use any other library other than stdio.h or uses
arrays/strings or uses global variables- 0 marks!
Looking at the code
Program layout and readability including: is the code indented, does it have
comments, header comments and meaning variable names?
ACS130留学生程序代做、Software编程语言代做、代写c++设计编程
Running the code, using a test input
Does the code do what is asked in this assignment briefing when tested? Read
line, print to file, read from file and print numbers to screen, calculate and print
sum, calculate and print number of occurrences of number characters and prints
mean. Are the calculations correct?
Does it check for file and abort the program (with a suitable message) if the file
is not found?
Does it use the function float mean(float sum, float N) to find the mean, which
gets printed from main()?
Output to screen
Is the output on the screen in a clear layout? /1
Total marks possible /10
Penalties for late submission
A late submission will be any assignment not submitted to Blackboard by the deadline. Late
submissions will incur the usual penalties of a 5% reduction in the mark for every day (or part
thereof) that the assignment is late and a mark of zero for submission more than five days
late.
Unfair means
You are permitted to view the resources on ACS130 Blackboard, C text books and C programs
published on the internet, for insight into C programming, but you are not permitted to copy
any code that you have not written to submit as your own work. You are not permitted to seek
or accept help on this assignment, or code for this assignment, from any internet site or forum.
You are not permitted to work with any other person on this assignment, and you are not
permitted to submit any other person’s algorithm or code as your own work. Any suspicion
of the use of unfair means will be investigated and may lead to penalties. References
must be provided to any other work that is used to inform the ideas for this assignment. See
http://www.shef.ac.uk/ssid/exams/plagiarism for more information.
Extenuating Circumstances
If you have medical or serious personal circumstances which cause you to be unable to submit
this assignment on time or which may have affected your performance, please inform me, and
complete and submit an extenuating circumstances form along with documentary evidence of
the circumstances. See http://www.sheffield.ac.uk/ssid/forms/circs.
Help
This assignment briefing and the lectures and resources on the ACS130 Blackboard course
and the training in C practice sessions provide all the information that is required to complete
this assignment. It is not expected that you should need to ask further questions. If you
need clarifications on the assignment, then please post a question on the ACS130
Blackboard discussion board. The discussion board allows everyone the chance to view an
answer to a question, as well as the opportunity to contribute to the discussion.
