(a)Implement all the classes. The formula for calculating salary for each class is shown below: For the Employee class, salary = basic salary + allowance For the Manager class , salary = basic salary + allowance + travel claims For the Clerk class , salary = basic salary + allowance + overtime pay,where overtime pay = overtime hours x overtime rate. Set overtime rate as RM3.50. Write a client program that creates an array named empArray that stores an object of an Employee,a Manager and a Clerk.In your program, include a method called printElements() that takes an array as parameter and prints the type of employee, the object’s data field values (by invoking thetoString() method) and the monthly salary.
objective of the project: Implement a class address. An address has a house number street optional apartment number city state postal code. All member variables should be private and the member functions should be public. Implement two constructors: one with an apartment number one without an appartment number. Implement a print function that prints the address with the street on one line and the city, state, and postal code on the next line. Implement a member function comesBefore that tests whether one address comes before another when the addresses are compared by postal code. Returns false if both zipcodes are equal. Use the provided main.cpp to start with. The code creates three instances of the Address class (three objects) to test your class. Each object will utilize a different constructor. You will need to add the class definition and implementation. The comesBefore function assumes one address comes before another based on zip code alone. The test will also return…

Salary (double) Write a program to create array of objects for the same to access these. Also, make use of member functions to accept values and print the name, age, designation and salary.
Description: Create a class named ComparableDog that extends Animal and implements Comparable interface. Implement the compareTo method to compare the Dogs on the basis of age. Write a test class to find the bigger age of two instances of ComparableDog Objects, and complement the ComparableDog class with the missing part. 1) The test program, the ComparableDog class, and its super class Animal are given as follows. // Main method public static void main(String[] args) { // Create two comparable Dogs ComparableDog dog1 = new ComparableDog(3); ComparableDog dog2 = new ComparableDog(4); System.out.println("Dog1:" + dog1); System.out.println("Dog2:" + dog2); if(dog1.compareTo(dog2) == 1) System.out.println("Dog1 is older than Dog2"); else if(dog1.compareTo(dog2) == -1) System.out.println("Dog1 is younger than Dog2"); else System.out.println("Dog1 and Dog2 have the same age"); }…
Write a class Travel having two private data members (distanceCovered , Time) The class has three constructors which are • having no parameter – for setting values to zero or null. • having two parameters for assigning values to both data members. • Overload the above constructor and use this keyword to set the values of data members. • Provide getters/setters for data members. • A function which calculates and display speed of traveling. • Write a function show() displays values. Write test Application that demonstrates the Run class by calling all the three constructors and method, creating a Create Travel objects, and then display the traveling with speed. Calculate highest speed. Programming language : java
Using Cpp/C++ Create an Account class that a bank might use to represent customers’ bankaccounts. Include a data member of type int to represent the account balance. [Note: In subsequentchapters, we’ll use numbers that contain decimal points (e.g., 2.75)—called floating-point values—to represent dollar amounts.] Provide a constructor that receives an initial balance and uses it to initializethe data member. The constructor should validate the initial balance to ensure that it’s greaterthan or equal to 0. If not, set the balance to 0 and display an error message indicating that the initialbalance was invalid. Provide three member functions. Member function credit should add anamount to the current balance. Member function debit should withdraw money from the Accountand ensure that the debit amount does not exceed the Account’s balance. If it does, the balanceshould be left unchanged and the function should print a message indicating "Debit amount exceededaccount balance." Member…

Exercise #1: Write a program with a class that contains an array of integers. Initialize the integer array in the constructor of the class. Then create two friend functions to the class to find the largest and smallest integers in the array. Create a destructor that sets all of the elements in the array to 0.
Write in python. Write a class named Employee that has **private** data members for an employee's name, ID_number, salary, and email_address. It should have an init method that takes four values and uses them to initialize the data members. It should have get methods named get_name, get_ID_number, get_salary, and get_email_address.Write a separate function (not part of the Employee class) named **make_employee_dict** that takes as parameters a list of names, a list of ID numbers, a list of salaries and a list of email addresses (which are all the same length). The function should take the first value of each list and use them to create an Employee object. It should do the same with the second value of each list, etc. to the end of the lists. As it creates these objects, it should add them to a dictionary, where the key is the ID number and the value for that key is the whole Employee object. The function should return the resulting dictionary.For example, it could be used like…
array of Payroll ObjectsDesign a PayRoll class that has data members for an employee’shourly pay rate and number of hours worked. Write a program withan array of seven PayRoll objects. The program should read thenumber of hours each employee worked and their hourly pay ratefrom a file and call class functions to store this information in theappropriate objects. It should then call a class function, once foreach object, to return the employee’s gross pay, so this informationcan be displayed.
