Define a class called ParkingLot with the following description:
Instance variables/data members:int vno — To store the vehicle number.int hours — To store the number of hours the vehicle is parked in the parking lot.double bill — To store the bill amount.
Member Methods:void input() — To input and store the vno and hours.void calculate() — To compute the parking charge at the rate of ₹3 for the first hour or part thereof, and ₹1.50 for each additional hour or part thereof.void display() — To display the detail.
Write a main() method to create an object of the class and call the above methods.
