(Combining Class Time and Class Date) Combine the modified Time class of Exercise 17.7and the modified Date class of Exercise 17.8 into one class called DateAndTime. (In Chapter 19, we’lldiscuss inheritance, which will enable us to accomplish this task quickly without modifying the existing class definitions.) Modify the tick function to call the nextDay function if the time increments into the next day. Modify functions printStandard and printUniversal to output the dateand time. Write a program to test the new class DateAndTime. Specifically, test incrementing thetime into the next day.
Write in C++ Language.
(Employee Record): Create a class named 'Staff' having the following members: Data members - Id – Name - Phone number – Address - AgeIt also has a function named 'printSalary' which prints the salary of the staff.Two classes 'Employee' and 'Officer' inherits the 'Staff' class. The 'Employee' and 'Officer' classes have data members 'Top Skill' and 'department' respectively. Now, assign name, age, phone number, address and salary to an employee and a officer by making an object of both of these classes and print the same.
(Richer Shape Hierarchy) The world of shapes is much richer than the shapes included inthe inheritance hierarchy of Fig. 19.3. Write down all the shapes you can think of—both two-dimensional and three-dimensional—and form them into a more complete Shape hierarchy with asmany levels as possible. Your hierarchy should have the base class Shape from which class TwoDimensionalShape and class ThreeDimensionalShape are derived. [Note: You do not need to write any codefor this exercise.] We’ll use this hierarchy in the exercises of Chapter 20 to process a set of distinctshapes as objects of base-class Shape. (This technique, called polymorphism, is the subject ofChapter 20.)

As youprocess each Account, determine its type. If an Account is a SavingsAccount, calculate the amountof interest owed to the Account using member function calculateInterest, then add the interestto the account balance using member function credit. After processing an Account, print the updated account balance obtained by invoking base-class member function getBalance.arrow_forward

You need to create a Date class for this purpose. Create objects of Date class in Manager and Employee classes to store respective dates. You need to write print function in Manager and Employee classes as well to print all information of Managers and Employees. You need to perform composition to implement this task. Create objects of Manager and Employee classes in main function and call print function for both objects. ______________________________________________________________ note : print the specific part of code in following ...

Write an abstract base class called Employee that declares an abstract method: signature double calculateSalary() This class must also define the following attributes: name (String type), enrollment (String type) and base_salary (double type). Use encapsulation and provide a constructor that receives the corresponding values to be stored in the respective attributes. This abstract class must be extended by the other classes representing the types of employees, so the classes Manager, Assistant and Salesperson must be written. In each class you must override the method calculateSalario so that the salary calculation is done like this: The manager receives twice the base_salary, the assistant receives the base_salary and the salesperson receives the base_salary plus a commission defined in the constructor of his class.

- (Operator Overloads in Templates) Write a simple function template for predicate functionisEqualTo that compares its two arguments of the same type with the equality operator (==) andreturns true if they are equal and false otherwise. Use this function template in a program thatcalls isEqualTo only with a variety of fundamental types. Now write a separate version of the program that calls isEqualTo with a user-defined class type, but does not overload the equality operator.What happens when you attempt to run this program? Now overload the equality operator (withthe operator function) operator==.

This default constructor calls the four-argument constructor. It has a four-argument constructor to assign values to the name, artist, year, and medium variables. It has a getter and settersfor the medium variable.

Question: Develop a polymorphic banking program using the Account hierarchy in which two types of Accounts can be created i.e.Current Account and Saving Account respectively. Each account must have to give the interest to the bank depending upon their account type. A function of name InterestRate() will calculate the interest of account and returns the interest amount. Current Account has annual interest rate of 0.1% of actual amount and SavingAccount will have to pay interest rate of 1.0% of actual amount. Also write a main function for polymorphic calls of the functions. Note: Polymorphic calls for the functions are necessary. Necessary constructor, Destructors, setters, getters and other functions should also be defined.arrow_forward
