For this task, you will implement a C++ program to simulate students’ lab enrollment. The UML diagrams are shown as following:
**Note: The attributes that marked ID, ID1, ID2 are the key attributes that can identify an object of those classes.**
You will define the classes `Subject`, `Student`, `Lab`, associated classes `Enrolment` and `Allocation` according to the UML diagrams above.
Define a class `Subject` in a file `Subject.h` with data members shown in the UML diagrams above. Implement necessary member functions (such as constructors, set and get functions, print function) in a file `Subject.cpp`.
Define a class `Student` in a file `Student.h` with data members shown in the UML diagrams above. Implement necessary member functions in a file `Student.cpp`.
Define a class `Lab` in a file `Lab.h` with data members shown in the UML diagrams above. Implement necessary member functions in a file `Lab.cpp`.
Define a class `Enrolment` in a file `Enrolment.h` with data member student number, subject code, enrolled date. Implement necessary member functions in a file `Enrolment.cpp`.
Define a class `Allocation` in a file `Allocation.h` with data member student number, lab ID and subject code. Define a class AllocationNode with an object of Allocation, and a pointer of `AllocationNode` in the file `Allocation.h`. Define a class `AllocationList` with two pointers of AllocationNode in the file Allocation.h. One pointer points to the head, another pointer points to the tail of a linked list. The classes AllocationNode and AllocationList will be used to make a linked list to store the lab enrolments.
Implement necessary member functions in a file `Allocation.cpp` for the classes Allocation, AllocationNode and AllocationList. The member functions allow the program to create Allocation, AllocationNode objects (constructors or set functions), add new node at the end of the linked list (e.g. push_back(const Allocation &)), search lab allocation information by using pointers of the linked list.
Define a class Admin in a file `Admin.h` with data members:+ A pointer points to a dynamic array of Student objects;+ An integer stores the total number of Student objects;+ A pointer points to a dynamic array of Subject objects;+ An integer stores the total number of Subject objects;+ A pointer points to a dynamic array of Lab objects;+ An integer stores the total number of Lab objects;+ A pointer points to a dynamic array of Enrolment objects;+ An integer stores the total number of Enrolment objects;+ An object of a linked list for students’ lab allocations.
Implement member functions described below in a file `Admin.cpp`:+ A function loads student’s records from a given text file into a dynamic array of students.+ A function loads subject’s records from a given text file into a dynamic array of subjects.+ A function loads lab’s records from a given text file into a dynamic array of labs.+ A functions loads enrolment’s records from a given text file into a dynamic array of enrolments.+ A function prints all students’ information that loaded.+ A function prints all subjects’ information that loaded.+ A function prints all labs’ information that loaded.+ A function prints all enrolments’ information that loaded.+ A function displays subjects’ codes for a student.+ A function displays labs’ IDs for a subject.+ A function manipulates lab allocations for students.+ A function prints out lab allocation list for each lab.+ Other necessary member functions.
Implement **main()** in a file `main.cpp` that gets command line inputs, declares an object of Admin, then call the member functions of **Admin** to load all records for students, subjects, labs and enrolments, display loaded records, manipulates students lab allocations by student’s number, subject code and lab / tutorial ID. The manipulation function should verify the input values for the student’s number, subject code and lab / tutorial ID. At the end, the program will print lab enrolment list for each lab. The details can be found at Testing section.
**Note: Do not put statement “using namespace std;” in the head files. Do not define public data members for the classes.**
**Testing:**
In the working directory on banshee, you can compile the program by
CC –o ass1 main.cpp Admin.cpp Subject.cpp Student.cpp Enrolment.cpp Lab.cpp Allocation.cpp
Or to make it simple, you can compile the program by
CC –o ass1 *.cpp
To run the program, you should pass the file names to the main() by
./ass1 student_filename subject_filename lab_filename enrolment_filename
You can download the test files **subjects.txt, students.txt, labs.txt** and **enrolments.txt** from this site.
**Note: Do not define constant files’ names inside the source code.**
You can use command **bcheck** on banshee to check if there is any memory leak by
bcheck ass1 student_filename subject_filename lab_filename enrolment_filename
In the following testing example, data in bold denote input data from keyboard.
