IN C++as soon as possible 1. Write a program having a base class Student with data members rollno, name and Classdefine a member functions getdata() to input values and another function putdata() todisplay all values. A class Test is derived from class Student with data membersTlmarks, T2marks, T3marks, Sessional1, Sessional2, Assignment and Final. Alsomake a function getmarks() to enter marks for all variables except Final and also makea function putmarks() to display result. Make a function Finalresult() to calculatevalue for final variable using other marks. Then display the student result along withstudent data.2. Write a program that declares two classes. The parent class is called Simple that hastwo data members numl and num2 to store two numbers. It also has four memberfunctions.The add() function adds two numbers and displays the result.• The sub() function subtracts two numbers and displays the result.• The mul() function multiplies two numbers and displays the result.• The div() function divides two numbers and displays the result.The child class is called Complex that overrides all four functions. Each function inthe child class checks the value of data members. It calls the corresponding memberfunction in the parent class if the values are greater than 0. Otherwise it displayserror message.3. An electricity board charges the following rates to domestic users to discourage largeconsumption of energy.• For the first 100 units – 50 P per unit• Beyond 100 units – 60 P per unitIf the total cost is more than Rs.250.00 then an additional surcharge of 15% is addedon the difference. Define a class Electricity in which the function Bill computes thecost. Define a derived class More_Electricity and override Bill to add the surcharge. 4. (Package Inheritance Hierarchy) Package-delivery services, such as FedEx",DHL° and UPS", offer a number of different shipping options, each with specificcosts associated. Create an inheritance hierarchy to represent various types ofpackages. Use Package as the base class of the hierarchy, then include classesTwoDayPackage and OvernightPackage that derive from Package. Base class Packageshould include data members representing the name, address, city, state and ZIP codefor both the sender and the recipient of the package, in addition to data members thatstore the weight (in ounces) and cost per ounce to ship the package. Package'sconstructor should initialize these data members. Ensure that the weight and cost perounce contain positive values. Package should provide a public member functioncalculateCost() that returns a double indicating the cost associated with shipping thepackage. Package's calculateCost() function should determine the cost by multiplyingthe weight by the cost per ounce. Derived class TwoDayPackage should inherit thefunctionality of base class Package, but also include a data member that represents aflat fee that the shipping company charges for two-day-delivery service.TwoDayPackage's constructor should receive a value to initialize this data member.TwoDayPackage should redefine member function calculateCost() so that it computesthe shipping cost by adding the flat fee to the weight-based cost calculated by baseclass Package's calculateCost() function. Class OvernightPackage should inheritdirectly from class Package and contain an additional data member representing anadditional fee per ounce charged for overnight-delivery service. OvernightPackageshould redefine member function calculateCost() so that it adds the additional fee perounce to the standard cost per ounce before calculating the shipping cost. Write a testprogram that creates objects of each type of Package and tests member functioncalculateCost().
