Create a base class called Shape with two data members of double type

which could be used to compute the area of figures. Derive two specific

classes called Triangle and Rectangle from the base class Shape. Add to the

base class, a member function called Get Data to initialize base class data

members and another member function display Area to compute and display

the area of figures. Make display Area a virtual function and redefine this

function in the derived classes to suit their requirements. Using these three

classes design a program which will accept dimensions of a triangle or

rectangle interactively and display the area.

Write a program to create a class called STUDENT with data members Roll

Number, Name and Age. Using inheritance, create the classes

UGSTUDENT and PGSTUDENT having fields a semester, fees and

stipend. Enter the data for at least 5 students. Find the average age for all

UG and PG students separately.

Modify the program no. 1 as follows:

Derive a class named as CYLINDER from CIRCLE class. Take necessary

data & member functions for this class to calculate the volume of the

cylinder. Show the result by accessing the area method of circle and

rectangle through object of rectangle class and the area of circle and volume

method of cylinder class through the objects of cylinder class.

Modify the program no. 1 as follows:

Derive a class named as BOX from RECTANGLE class. Take necessary

data & member functions for this box class to calculate the volume of the

box. All the data members are initialized through the constructors. Show the

result by accessing the area method of circle and rectangle and the volume

method of box class through the objects of box class.

Write a program to create a class CIRCLE with one

field as radius, used to calculate the area of a Circle. Create another class

RECTANGLE used to calculate the area of the rectangle which is a subclass

of CIRCLE class. Use the concept of single inheritance such that the radius

of circle class can be re-used as length in rectangle class. Take necessary

data members and member functions for both the classes to solve this

problem. All the data members are initialized through the constructors.

Show the result by accessing the area method of both the classes through the

objects of rectangle class.

Bianca is preparing special dishes for her daughter’s birthday.

It takes her a minutes to prepare the first dish, and each following dish takes b minutes longer than the previous dish. She has t minutes to prepare the dishes.

For example, if the first dish takes a = 10 minutes and b = 5, then the second dish will take 15 minutes, the third dish will take 20 minutes, and so on.

If she has 80 minutes to prepare the dishes, then she can prepare four dishes because 10 + 15 + 20 + 25 = 70.

Write a program that prompts the user to enter the values of a, b, and t, and outputs the number of dishes Bianca can prepare.

Write a program called National_lottery. it should use rand function to produce 6 random numbers to 0 & 49, number must not repeat. use an appropriate pointer to print address of numbers in memory and its must be in hexadecimal. use derefencing operator to point in address. use function sort with begin() & end() function to organise values in ascending order, use a for statement to intialise numbers into arrays. Search any 2 array element that give sum of >=80 when + together, if numbers >=80 are more than 1 set, consider the biggest set chosen for draw. if the value of sum of the 2 are >=80, print "You won" & if they are < 80, print "You loose". Amount won by custom made function "amountDeterminat" of type & double argument in prototype. argument will be winning number received from sum of 2. amountDeterminant must use switch conditions. if winning numbers is (80 & 83 won amount 1700000, 84 & 86 amount 2500000, 87 & 89 amount 16000000)
