WAP to show the working of abstract class by considering suitable example

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

function.

Hypotenuse Calculations) Define a method hypotenuse that calculates the hypotenuse of a right triangle when the lengths of the other two sides are given. The method should take two arguments of type double and return the hypotenuse as a double. Incorporate this method into an application that reads values for sidel and side 2 and performs the calculation with the hypotenuse method. Use Math methods pow and sqrt to determine the length of the hypotenuse for each of the triangles in Fig. $6.15 .[$ Note: Class Math also provides method hypot to perform this calculation.]

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.

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.

Write a method integerPower ( base, exponent ) that returns the value of ? base exponent

For example, integerPower (3,4) calculates 34( or 3∗3 in 3∗3).34( or 3∗3 in 3∗3). Assume that exponent is a positive, nonzero integer and that base is an integer. Method integerPower should use a for or while statement to control the calculation. Do not use any math library methods. Incorporate this method into an application that reads integer values for base and exponent and performs the calculation with the integerPower method.

A parking garage charges a $2.00 minimum fee to park for up to three hours. The garage charges an additional $0.50 per hour for each hour or part thereof in excess of three hours. The maximum charge for any given 24-hour period is $10.00. Assume that no car parks for longer than 24 hours at a time. Write an application that calculates and displays the parking charges for each customer who parked in the garage yesterday. You should enter the hours parked for each customer. The program should display the charge for the current customer and should calculate and display the running total of yesterday’s receipts. It should use the method calculateCharges to determine the charge for each customer.

Write an algorithm to compute the average of three input quizzes. Then display The result.
