The class Result derives information from two branch, find: 1- Define all the five classes, and read data for the base classes by using: a- Initialize the data members by using constructor. b- read the string data (Em_name and Wo_name), by using dynamic constructor. 2- Find the grater salary of each employee and worker? by using friend function. 3- Display the employee or worker information that have the grater salary. 4- Write a main program to create one object and using the implicitly constructor calling method to send all the data members are required. Emp info Em address Em salary Sci_info grater_salary() Wo address Wo salary Friend function Worker Employe Em code, Em name Wo code, Wo name Result Display()

3. Design a user-defined class called Course. Each course object will hold data about a course. The data includes courseID, courseName, credits and instructorName. Define the instance variables required of the appropriate type. Provide only get methods along with toString() and equals() methods. Design another user-defined class called Student. Each student object will hold data on name, GPA and courseList. Make sure to define courseList as an ArrayList holding references to Course objects Implement a constructor that will take values to initialize name, and gpa while courseList is initialized to an ArrayList() object. Provide the following get methods: getStudent ID ( ), getName(), getGPA (), get Gender(), and get CourseList() Note: the getCouresList() method will return a copy of the coureList arraylist with copies of course objects. Provide the following set methods: setName(), setGPA (), setGender() Another method: addCourse () that will take a Course object and add it to the…
Indications:Person is an abstract class containing the abstract method Print().In Teacher and Student the method print() will print the information of either Teacher or Student.Write the class university corresponding to the following UML diagram. It contains three attributes.Tab is an array of Person. sizeTab is the size of Tab. The attribute n represents the number of elements added to the tab. When the tab is empty n is equal to 0.The constructor University(sizeTab) will initialize the different attributes and allocate the memory to the array Tab.addPerson(p:Person) will add the new person to Tab. The method printAll() will print all the information of the Persons inside Tab.Write the main method. Create three Teacher and three Student and add them to University Object and print them all.
Object passing checklist1. Go over each member function and add the const keyword after their declaration ifthey do not modify any of the class' member variables.2. When accepting objects as parameters, prefer to pass them by reference. Add reference declarator (& before the identifier name of an object parameter.3. If the member function does not modify the parameter, make the parameter constantby using the const keyword. apply the Object Passing Checklist. Modify food.h and volunteer.h to useobject references. Add const and & keywords in the appropriate places of the code.
. Given the following classes, answer the question. Director (extend the class Person) that has the following: Data Fields: private double salary. Constructor: Constructor to create a Director object with specified name, address, and salary. Methods: Accessor and mutator methods for salary data field. Design UML diagram for the above classes. Write the code only for class Person and Class Student.
Write the entire class definition for a Person class that contains the following attributes: Assuming your definition of the Person class is complete in Question 4, in the space below • name - a str value representing the Person's name. • weight - an int value representing the weight of the Person (in Ibs, but this metric is write the definition for a Student class that inherits from the Person class. The Student class must irrelevant for this problem). • contain an additional int attribute named pern. • define its own constructor that takes in a name (str), weight (inti, and perm (int) parameters. For this implementation, you can assume all parameters will be passed in and no default Your class definition should contain the following methods and correct behavior: • A constructor that sets the Person's name and weight to the object. An empty string (*) values are needed. Note: the Student constructor must utilize the Person constructor in order to set the nane and weight values…
Design a class called Bird that includes three pieces of information as data members-name (type string), species (type string) and a sizeInInches (type int).Define virtual function getCageSize ().Your class should have a constructor that initializes the three data members. Provide setter and getter function for each data member.Overload the virtual function of inherited class. Write a main part which creates the Bird class and a derived class Vulture.
Create a class named Line: (a) Define private data members p1 and p2 as pointer to Point objects (the one we had in lectures), slope and length as double variables. (b) Define setter and getter functions. (c) Define a null-constructor that initializes numeric variables with zero and allocate dynamic memory for points and initialize them to [0,0] as well. (d) Overload a constructor that allocates memory for points, initilize them with given arguments, and calculate the slope and length. (e) Implement destructor, copy constructor and copy assignment operator. (f) Create a function called ”parallel” that takes too Line objects, returns true when given lines are parallel and returns false otherwise. (g) Overload the less than (<) and greater than (>) and equality (==) operators (compare the length). (h) Write a functions that reads lines in the format provided in the lines.txt from the file (without any change) and stores them in a vector named Lines. (i) Sort the objects of Lines…
Create a UML Class Model based on the requirements . Your Class Model is to include: All classes Attributes and Attribute Types Associations Multiplicity Primary and Foreign keys Any Inheritance, Composition or Aggregation. Building Maintenance system. A rental property management company wants to develop a ‘Building Maintenance System.’ This system will be used by the company to manage maintenance requests from tenants in the several rental buildings that it manages in the city. Each building has a maintenance manager. The maintenance manager is responsible for creating accounts in the system for each tenant in their building. A tenant can rent multiple apartments within the same building. Tenants can submit maintenance requests using this system. Each maintenance request will have a request ID, category, and description. The maintenance manager manages a maintenance crew in their building. Maintenance crew members can be members of more than one maintenance team. Maintenance crew…
Write a base class (Person) that has the following data members: String name, long NID, int age. Your class (Person) should have setters and getters for all data members. Derive a class (Student) from class (Person). Class student should have the following private data members: Int id, double GPA, string major. Class (Student) should have setters and getters for its private data members. In your main function, create an object of class (Student) and set all of its data members.
Define a default constructor that initializes the data members, string title and integer year, with the default values "Empty" and -1, respectively. Ex: If the input is Magnolia 1989, then the output is: Title: Empty, Year: -1 Title: Magnolia, Year: 1989 Note: The class's print function is called first after the default constructor, then again after the inputs are passed to the setters. 5 class Book { 6 public: 7 8 9 10 11 12 13 14 15 }; 16 Book(); void SetTitle(string bookTitle); void Set Year (int bookYear); void Print (); private: string title; int year; 17 Your code goes here */ 18 19 void Book::SetTitle(string hook Title) { CS Scarint (19 bi Title mscanner 22 23 void Book Set Year(int bookYear) [ 2
