function to set unit_used. Upto 200 units 3 rupees per unit, 201 to 500, 4 rupees per and above 500

5.5 rupees per unit are allotted by EB. Calculate the bill amount and display the amount. Create

another class Salary with basic, DA and HRA. Set basic by a member function. 104 percent of basic

is assigned as DA and 10 percent is allotted as HRA. Display the total salary. Derive a class Budget

contains income, tuition_fee, house_rent, saving, grocery, eb_bill as data members. Set the values

and get the values of income and eb_bill from parent classes. Display the budget details.
