Start with the publication, book and tape classes. Add base class sales that holds an array of three floats so that it can record the dollar sales of a particular publication for the last three months. Include a getdata() function to get three sale amount from the user and a putdata() function to display the sales figure. Alter the book and tape classes, so they are derived from both publication and sales. An object of book or tape should should input and output ans sales data along with other data. Write a main function to create a book and tape object and exercise their input/output capabilities.

Create a class of Company having private data members. Make all constructors along with setter getter. Also make a print function that can print all the information of that company.
· Exercise # 2: Implement a class Portfolio. This class has two objects, checking and saving, of the type bankAccount that was developed in the worked example. Initialize the 2 bank accounts with 0 initial balance. . Implement four methods • def deposit (self, amount, account) • def withdraw (self, amount, account) • def transfer (self, amount, account) • def getBalance (self, account) • Here the account string is "S" or "c" for Saving and Checking, respectively. For the deposit or withdraw, it indicates which account is affected. For a transfer, it indicates the account from which the money is taken; the money is automatically transferred to the other account. • To test your class: . create one Potfolio object • deposit 10000 in its checking account . transfer 5000 from checking account to saving account . withdraw 2500 from checking account display the balance of both accounts • A run for the above test program will result in the following output 5000.0 Saving balance = Checking…
Add a member function having return type boolcalled isOversize( ) to the publication class. Let’s say that a publication is Oversized if it has pages more than 550. You can access this function from main() using the objects created and display the string “Oversized” or “Not Oversized” for oversize/not oversized publication. Use the return value of the function to display the specified string.(use if … else…).
Consider a class BankAccount that has • Two attributes i.e. accountID and balance and• A function named balanceInquiry() to get information about the current amount in the account Derive two classes from the BankAccount class i.e. CurrentAccount and the SavingsAccount. Both classes (CurrentAccount and SavingsAccount) inherit all attributes/behaviors from the BankAccount class. In addition, followings are required to be the part of both classes• Appropriate constructors to initialize data fields of base class• A function named amountWithdrawn(amount) to withdraw certain amount while taken into account the following conditionso While withdrawing from current account, the minimum balance should not decrease Rs. 5000o While withdrawing from savings account, the minimum balance should not decrease Rs. 10,000• amountDeposit(amount) to deposit amount in the accountIn the main() function, create instances of derived classes (i.e. CurrentAccount and SavingsAccount) and invoke their respective…

: Imagine you have a call center with three levels of employees: respondent, manager,and director. An incoming telephone call must be first allocated to a respondent who is free. If therespondent can't handle the call, he or she must escalate the call to a manager. If the manager is notfree or not able to handle it, then the call should be escalated to a director. Design the classes anddata structures for this problem. Implement a method dispatchCall () which assigns a call tothe first available employee.
Question 2: Suppose you have the following scenario: People who use the Palm Tree System are either farmers or experts. They both have name and phone number. The farmer has address and has the ability to search and buy a product, reserve an appointment and add comments. An expert has a number of years of experience and can answer questions and post advices. An Expert can communicate with many farmers while a farmer can communicated by only one expert. By using Star UML tool, draw a Class diagram for this scenario.
1. Create a Student class that implements the Person interface. As well as storing the students name and email, also store their course grade (e.g A, B, C) in a member variable. The grade should be accessible via a getGrade method. For the implementation of getDescription return a message along the lines of “A C grade student”, substituting the students actual grade.2. Create a Lecturer class that implements the Person interface. This class should also store the subject that the lecturer teaches. Add a getSubject method, and implement getDescription so that it returns a suitable message, e.g. “Teaches Biology”.3. Create a third class, Employee that implements the interface. This should also store the name of the department the Employee works in (available via getDepartment). Again, getDescription should return a suitable message.
1- Create a class SchoolKid that is the base class for children ar aschool . It should have attributes of the child’s name and age ,the name of the child’s teacher ,and the greeting. It should haveappropriate accessor and mutator methods for each of the attributes. Derive a class ExaggeratingKid from schoolkid , as described above . The new class should override the accessor method for the age , reporting the actual plus 2. It also should override the accessor for the greeting ,returning the child’s greeting concatenated with the words “I am the best”.
Create a class Student that contains three members: roll no, name and mark, and threefunctions. Write a first inputStudent() function to get data of student class. Write a secondgetMark() function that returns a student’s mark. Write a third display() function thatdisplays a student’s data. In a main() function, you need to declare 40 students and get dataof all students by using inputStudent() function. And also use a pointer array to keep allstudents by mark greater than 50 and display the searching data of each student in thatpointer array (Use the access operator -> to access a pointer points to member functions ofthe Student class)
Define a class that captures airline tickets. Name the class as Airline Ticket. Each ticket lists the departure and arrival cities, a flight number, and a seat assignment. A seat assignment has both a row and a letter for the seat within the row (such as 12F). Include appropriate constructor, destructor and a print fucntion in your class definition. Make two examples of tickets and print the values using the print member function.
Consider a class named Calculator with typical four specific functionalities i.e. addition, subtraction, multiplication, and division. Implement these functionalities as four functions with two parameters. It is also required to overload all these functions for int and double data types. In the main function, create an object of class Calculator and invoke its member functions while passing parameters of int and double type.
