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.

A C++ program to print the members of a structure using dot operators

Create a file named “Circle.txt” and write the following data:

Circle 1, 5

Circle 2,10

Circle 3,4

Each Line has a Circle Name(Circle 1 as in example in 1st line above) and its radius separated by a comma. You have to calculate the Area of

each circle using (pi*r*r) and write it at the end of every line. (5+ 10)

e.g.

Circle 1 , 5, 78.5

Circle 2, 10, 314

Circle 3, 4, 50.24

Objective: 

Design a class called NumDays. The class’s purpose is to store a value that represents a number 

of work hours and convert it to a number of days. For example, 8 hours would be converted to 

1 day, 12 hours would be converted to 1.5 days, and 18 hours would be converted to 2.25 days. 

The class should have a constructor that accepts a number of hours, as well as member 

functions for storing and retrieving the hours and days. 

The class should also have the following overloaded operators: 

• + Addition operator. When two NumDays objects are added together, the 

overloaded + operator should return the sum of the two objects’ hours members. 

• − Subtraction operator. When one NumDays object is subtracted from another, 

the overloaded − operator should return the difference of the two objects’ hours 

members.

We are going to create class of Matrix. You have to write the definition of the following function given below in the Matrix class. class Matrix{ private: int noOfRows ; int noOfColumns; int ** data; public: Matrix(int noOfRows, int noOfColums); void displayData(); -Matrix(); Matrix(const Matrix & ref);You have to write down the definition of following functions. 1. Matrix(int noOfRows, int noOfColums) 2. void displayData0; 3. -Matrix(); 4.Matrix(const Matrix & ref)

Create a calculator for the complex number by creating a class of complex number (with two member variables, required constructor(s) and functions) with overloading all operators in it.(Operators: ++,--,+,-,/,*).
