Create a class named ‘CalculateArea’ to calculate the area of three different diagrams i.e. Rectangle, Triangle and a Square using function overloading.

First prompt the user to select the diagram for which he wants the area:

Press 1 for Rectangle

Press 2 for Triangle

Press 3 for Square

After the selected option, call the respective function of the selected diagram and print the area.

Area of rectangle: length*width;

Area of triangle: ½(base*height);

Area of square: (length)²

Write a program that creates a class called student. The data members of the class are name and age.

·      Create a nullary constructor and initialize the class object.

·      Create a parameterized constructor that can set the values being passed from the main function.

·      Create a display function called showall( ) which will be used to show values that have been set.

Use the default copy constructor to show that copying of simple objects can be accomplished through the use of the default copy constructor.

Write a C++ program to enter salary and output income tax and net salary using multiple inheritance concept.

Note: Use Linked List to implement stack.

A stack is an object that allows the following operations:

 Push: Add an element to the top of a stack

 Pop: Remove an element from the top of a stack

 IsEmpty: Check if the stack is empty

 Peek: Get the value of the top element without removing it

Create a class to define above mention operations of stack along with some addition functionality:

i. Copy a stack to another one.

ii. Delete an element at a specified location.

iii. Returns the count of elements in a stack.

iv. Insert an element at a specified location.

Write a main function to test the functionality of above class.

Remember: To access any element that is not at top, you have to first pop all other elements on the top of that.
