Assignment 1 solution

Objective
This assignment aims to establish a basic familiarity with C++ classes.
General Requirements
• Follow the common principles of OO programming when you design your classes
• Put your name, student number at the beginning of each source file
/*------------------------------------------------------
Student's Name:
Student's email address:
Laboratory group (group code and time):
Purpose of this assignment:
-------------------------------------------------------*/
• Add comments to the source code to make your solution easier to follow
• Logical structures and statements are properly used for specific purposes

Design requirements:
Write a program to read a list of students from a text file the name of which should be provided from a command line. Create a dynamic array to store the students’ records loaded from the file. The format of the data file is as follows:

Albert Einstein 52 67 63
Steve Abrew 90 86 90 93
David Nagasake 100 85 93 89
Mike Black 81 87 81 85
Andrew Van Den 90 82 95 87
Joanne Dong Nguyen 84 80 95 91
Chris Walljasper 86 100 96 89
Fred Albert 70 68
Dennis Dudley 74 79 77 81
Leo Rice 95
Fred Flinstone 73 81 78 74
Frances Dupre 82 76 79
Dave Light 89 76 91 83
Hua Tran Du 91 81 87 94
Sarah Trapp 83 98
The first line has a number equal to the total number of records. Each line shows one student’s record with the name and marks for different subjects.
Define a class Student in a file student.h according to the description below:
• The class has a private data member name of type char*
• The class has a private data member marks that store marks of all subjects (up to 4 subjects)
• The class has a private data member num that holds the number of subjects that have been chosen
• Define appropriate constructors and a destructor
• Define necessary public member functions that can get values of data members
and print out results Implement member functions of Student in a file student.cpp
Write a program a1main.cpp to initialise the array of students by reading the students’ records from a text file. After all records have been read, the program shall print the marks for each student along with the total mark and average mark. After all records have been printed, the program shall print the total marks and the average marks for each subject. The program should have appropriate error detection and error recovery in case the data file is corrupted.
You need to use dynamic memory allocation to store student’s name for this task. Make sure there is no memory leak. Do not forget to include namespace in your program files.
You can use the command bcheck on banshee to check if there is any memory leak.

You need to follow good programming practices when you write the source code:
- meaningful identifiers for data members, member functions, classes
- no global variables
- appropriate indentation
- appropriate comments
Testing:
Upload all source code files and the data file to your working directory on banshee.
Compile the program in the working directory on banshee, by
CC –o assignment1 a1main.cpp student.cpp
Run the program using:
task1 students.dat
The input test file students.dat is provided and can be downloaded from the subject
web site.
Note: Your program should work (and will be tested) with different data files which
follow the same file format. Do not define the file name as a constant inside your
source code.
The output of your program should be as follows:
Name Mark1 Mark2 Mark3 Mark4 Total Average

Submission:
All assignments must be submitted electronically via the submit system. For this
assignment you must submit all the files via the command (in one line):
submit -u your_user_name -c CSCI204 -a 1 a1main.cpp
student.h student.cpp
and enter your password.
Make sure that you use the correct file names. The UNIX system is case sensitive. You
must submit all files in one submit command line.
After submit your assignment successfully, please check your email of confirmation.
You should keep the email for the reference.
NOTES:
1. SUBMIT AS EARLY AS POSSIBLE. YOU CAN RESUBMIT LATER IF NECESSARY.
Only the latest submission will be marked.
3. SUBMISSION VIA EMAIL IS NOT ACCEPTABLE. YOU HAVE TO USE SUBMIT
COMMAND TO SUBMIT YOUR WORK.
4. ASSIGNMENT WITHOUT PROPERLY FILLED ASSIGNMENT HEADERS IN
SUBMITTED FILES WILL NOT BE MARKED
4. The submitted file names must be the same as in the submission example. Files with other
names will not be tested by the submit system and therefore will not be marked.
5. Enquiries about the marks can only be made within a maximum of 1 week after the assignment
results are published. After 1 week the marks cannot be changed.
6. The assignment is an individual assignment and it is expected that all its tasks will be solved
individually without any cooperation with the other students. If you have any doubts,
questions, etc. please consult your lecturer. Plagiarism will result in a FAIL grade being recorded
for that assessment task.
