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.
