Write a program having a base class Student with data members rollno, name and Class define a member functions getdata() to input values and another function putdata() to display all values. A class Test is derived from class Student with data members Tlmarks, T2marks, T3marks, Sessionall, Sessional2, Assignment and Final. Also make a function getmarks() to enter marks for all variables except Final and also make a function putmarks() to display result. Make a function Finalresult() to calculate value for final variable using other marks. Then display the student result along with student data.

1. Write a program having a base class Student with data members rollno, name and Class define a member functions getdata() to input values and another function putdata() to display all values. A class Test is derived from class Student with data members Tlmarks, T2marks, T3marks, Sessional1, Sessional2, Assignment and Final. Also make a function getmarks() to enter marks for all variables except Final and also make a function putmarks() to display result. Make a function Finalresult() to calculate value for final variable using other marks. Then display the student result along with student data. 2. Write a program that declares two classes. The parent class is called Simple that has two data members numl and num2 to store two numbers. It also has four member functions. 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 in the child class checks the value of data members. It calls the corresponding member function in the parent class if the values are greater than 0. Otherwise it displays error message. 3. An electricity board charges the following rates to domestic users to discourage large consumption of energy. • For the first 100 units – 50 P per unit • Beyond 100 units – 60 P per unit If the total cost is more than Rs.250.00 then an additional surcharge of 15% is added on the difference. Define a class Electricity in which the function Bill computes the cost. 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 specific costs associated. Create an inheritance hierarchy to represent various types of packages. Use Package as the base class of the hierarchy, then include classes TwoDayPackage and OvernightPackage that derive from Package. Base class Package should include data members representing the name, address, city, state and ZIP code for both the sender and the recipient of the package, in addition to data members that store the weight (in ounces) and cost per ounce to ship the package. Package's constructor should initialize these data members. Ensure that the weight and cost per ounce contain positive values. Package should provide a public member function calculateCost() that returns a double indicating the cost associated with shipping the package. Package's calculateCost() function should determine the cost by multiplying the weight by the cost per ounce. Derived class TwoDayPackage should inherit the functionality of base class Package, but also include a data member that represents a flat 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 computes the shipping cost by adding the flat fee to the weight-based cost calculated by base class Package's calculateCost() function. Class OvernightPackage should inherit directly from class Package and contain an additional data member representing an additional fee per ounce charged for overnight-delivery service. OvernightPackage should redefine member function calculateCost() so that it adds the additional fee per ounce to the standard cost per ounce before calculating the shipping cost. Write a test program that creates objects of each type of Package and tests member function calculateCost().
