[Solved] CSCI204 Assignment 3

This assignment aims to establish a basic familiarity with C++ classes. The assignment introduces increasingly object-based, C++ style of solution to a problem.General Requirements You should observe the common principles of OO programming when you design your classes. You should make proper documentation and implementation comments in your codes where they are necessary. Logical structures and statements are properly used for specific purposes.

ObjectivesOn completion of these tasks you should be able to: Code and run C++ programs using the development environment. Make effective use of the on-line documentation system that supports the development environment. Code programs using C++ in a hybrid style (procedural code using instances of simple classes) and in a more object-based style. Manipulate string data. Understand template and STLTasks:Task 1: Template (7 marks)Define and implement a template class ListNode in a namespace MYLIB in a file OrderedList.h, which has a template data member and two pointers that point to the previous ListNode object and next ListNode object. Define and implement necessary constructor(s) and other member functions in the file OrderedList.h.Define and implement a template class OrderedList as a container in a file OrderedList.h that can be used to store template data in a Doubly Linked List (DLL) with nodes ordered by the data values from the smallest one to the biggest one.Define two data members head and tail as pointers of ListNode type. They point to thehead and tail of a DLL.Define a nested class iterator in the template class OrderedList that can be used to traversal the DLL. It contains a data member of a ListNode pointer points to a node in the DLL. Define constructors, overloading operators, such as ++ (pre-fix and post-fix increment operator) that change an iterator points to the next node, * (dereferenceoperator) returns the data that the iterator points to, and != (not equal) to compare twoiterators in the class iterator.Define a constructor, destructor for the template class OrderedList.Define a member function begin() for the template class OrderedList that returns an iterator object points to the beginning of the DLL.Define a member function end() for the template class OrderedList that returns an iterator object points to the end of the DLL.Define a member function insert(const T &) for the template class OrderedList that take a template data as a parameter, insert a new node with the data value into the correct location in the DLL.Implement member functions for the template class OrderedList and nested class iterator in the file OrderedList.h.Define a class Student in a file Student.h, which contains student number, name andemail.Define overloading insertion operator (<<) to print out data members of a Student object.Define overloading extraction operator (>>) to get input data to a Student object.Define overloading comparison operator <= (or <) that compare two Students objects bytheir emails.Define necessary member functions, such as constructors, etc., for the class Student.Implement member functions, friend input operator, output operator for the class Student in a file Student.cpp.Download a file task1Main.cpp to test the DLL by different data (integers, doubles and Student objects). You will get data from the keyboard, add them into the ordered DLL, then print out results.Testing:You can compile the task 1 byCC o task1 task1Main.cpp Student.cppThen run the program like following (input data in red):./task1How many integers? 5Input an integer: 18Input an integer: 2Input an integer: 13Input an integer: 9Input an integer: 7Output integers:2 7 9 13 18How many doubles? 8Input a double: 17.5Input a double: 12.5Input a double: 11.3Input a double: 19.8Input a double: 18.4Input a double: 10.2Input a double: 21.4Input a double: 22.2Output doubles:10.2 11.3 12.5 17.5 18.4 19.8 22.2 31.4How many student records? 4Input number: 1234567Input name: Cart DongInput email: [email protected]Input number: 1234568Input name: Bob SmithInput email: [email protected]Input number: 1234570Input name: Mark TwainInput email: [email protected]Input number: 1234571Input name: Alice MontageInput email: [email protected]Output students:1234571, Alice Montage, [email protected]1234568, Bob Smith, [email protected]1234567, Cart Dong, [email protected]1234570, Mark Twain, [email protected]edu.auYou can download the testing file input1.txt from Moodle and save it into your working directory, test your program by using following method:./task1 < input1.txtNote: Your program of task 1 should work on different testing data.Task 2: file I/O and manipulations (5 marks)Download the source code Date.h and Date.cpp from Moodle for this task. (not available at this moment until assignment 2 submission been closed due to some ACs)Define a class Account in a file Account.h that contains data members account number, name, sex, date of birth (Date type), address and account balance. Define constructor(s), overloading operators, include assignment operator (=), less than and equals to operator (<=), insertion operator (<<), and extraction operator (>>) for the classAccount. Define other necessary member functions.Implement member functions and overloading operators for the class Account in a fileAccount.cpp.Define you own manipulator Currency that takes two integers as width and precision for the output of currency in the file Account.h. Implement the manipulator Currency in the file Account.cpp. The manipulator Currency will be used in the insertion operator for Account balance. The manipulator Currency will set output currency symbol as $, the width of output currency, the precision of currency and filled by zeros (0s) if the widthof currency is not long enough.Hint: Define fixed size char arrays instead of strings for some data members definedin the class Account (such as name, address).Hint: Use iomanip and Currency that defined to generate formatted outputs for theaccount records.Define a class AccountManagement in a file AccountManagement.h that contains adata member of a container OrderedList, which will be used to store account records.Define member functions: loadData(const char *) will load Account record from a given text file and storethe records in the container of OrderedList. displayData() will use iterator of OrderedList object to traversal the DLL anddisplay formatted output data of accounts. saveData(const char *) will save the accounts from DLL to a given binary file.Download a file task2Main.cpp to test your task 2.Testing:Use CC to compile the source files byCC o task2 task2main.cpp Account.cpp Date.cpp AccountManagement.cppand run the program by./task2 accounts.txt accounts.datThe output records on the screen can be found in a text file output2.txt.The input text file accounts.txt can be downloaded from Moodle. The sorted Accountrecords will be saved in a binary file accounts.dat.Note: Your solutions of task 2 should work on different testing data / files.Task3: STL map and iterator (2 marks)Use the source code files Date.h, Date.cpp, Account.h, and Account.cpp that used in task2.Define a class AccountMap in a file AccountMap.h. It contains a data member, whichis a multimap container that can be used to store Account records. The key of thecontainer is a char pointer of accounts name. You will define a comparison functionCompareCharArrays to compare two char arrays in the file AccountMap.h for themultimap object. For example:multimap<char *, Account, CompareCharArrays> accounts;Define a destructor for the class AccountMap to release dynamic memory allocated forthe container to avoid memory leaks.Define a member function loadData(const char *) for the class AccountMap that loadaccount records from a given binary file (created in task 2), insert the records into themultimap container.Define a member function displayData() for the class AccountMap that use iterator of thecontainer to display all records.Implement the member functions in a file AccountMap.cpp.Download a file task3Main.cpp from Moodle to test your task3.Testing:Use CC to compile the source files byCC o task3 task3Main.cpp Account.cpp Date.cpp AccountMap.cppand run the program by./task3 accounts.datThe binary file accounts.dat is generated by your task 2. The outputs of this task looklike the results in a text file output3.txt.Note: Your solutions should work on different testing data / files.SubmissionThis assignment is due by 11.59 pm (sharp) on Friday 6 June, 2014.Assignments are submitted electronically via the submit system.For this assignment you must submit the files via the command:$ submit -u your_user_name -c CSCI204 -a 3 OrderedList.h Student.h Student.cppAccount.h Account.cpp AccountManagement.h AccountManagement.cpp AccountMap.hAccountMap.cppand input your password.Make sure that you use the correct file names. The Unix system is case sensitive. Youmust submit all files in one submit command line.Since you can submit the assignment many times (but we only mark the latestsubmission), and you dont want to type the submit command like above every time, youmay save the above command script into a text file, e.g. submita3.sh, on banshee in thesame directory with the assignment 3 source files. Replace your_user_name by yourown login name. You should change the script file execution permission by$ chmod +x submita3.shThen you can execute the script file by$ ./submita3.shRemember the submit command scripts in the file should be in one line.Your program code must be in a good programming style, such as good names forvariables, methods, classes, and keep indentation.Submission via e-mail is NOT acceptable.After submit your assignment successfully, please check your email of confirmation. Youwould loss 50% of the marks if your program codes could not be compiled correctly.Late submissions do not have to be requested. Late submissions will be allowed for a fewdays after close of scheduled submission (up to 3 days). Late submissions attract a markpenalty; this penalty may be waived if an appropriate request for special consideration(for medical or similar problem) is made via the university SOLS system before the closeof the late submission time. No work can be submitted after the late submission time.A policy regarding late submissions is included in the course outline.The assignment is an individual assignment and it is expected that all its tasks will besolved individually without any cooperation with the other students. If you have anydoubts, questions, etc. please consult your lecturer or tutor during tutorial classes oroffice hours.
