(Pure Virtual Function) Write the above program by modifying by making display() as pure virtual

function.

Q1:Define a class ABC. Derive two classes BBC and KBC from ABC. All the classes contains same

member function name as display(). The base class pointer always holds the derived class objects.

a) Write a program such that base class pointer or reference will always access/call the base version

of the members available in derived class, do not have any access to the derived class members.

b) Write a program such that base class pointer or reference will always access/call the derived

version of the members available in derived class, do not have any access to the base class

members.

You are required to confirm the equation by a

simulation. In this simulation, you will consider how the ball moves

in very short time interval Δt.

I. You will assume that Δt is a constant double with a

value of 0.01. You can get the updated position using s = s + v * Δt. The velocity changes constantly—in

fact, it is reduced by the gravitational force of the earth. In a short time interval, Δv = –gΔt, you must

keep the velocity updated as v = v - g * Δt; In the next iteration, the new velocity is used to update the

distance.

You need to run the simulation until the cannon ball falls back to the ground. Your program should take

the initial velocity as an input. Update the position and velocity 100 times per second, but print out the

position only every full second. Also, printout the values from the exact formula s = vi t – (1/2) gt2

for the

comparison. Lastly plot the path that cannon ball will take to get the bonus marks.

Write a program that calculates the occupancy rate for a hotel. The program should start by asking the

user how many floors the hotel has. A for loop should then iterate once for each floor. In each iteration,

the loop should ask the user for the number of rooms on the floor and how many of them are occupied.

After all the iterations, the program should display how many rooms the hotel has, how many of them

are occupied, how many are unoccupied, and the percentage of rooms that are occupied. The

percentage may be calculated by dividing the number of rooms occupied by the number of rooms.

Input Validation: Do not accept a value less than 1 for the number of floors. Do not accept a number

less than 10 for the number of rooms on a floor.
