C++ OOP 1. Write a class declaration named Circle with a private member variable named radius. Write set and get functions to access the radius variable, and a function named getArea that returns the area of the circle. The area is calculated as 3.14159 * radius * radius. Add a default constructor to the Circle class, the constructor should initialize the radius member to 0.
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
C++ OOP
1. Write a class declaration named Circle with a private member variable named radius. Write
set and get functions to access the radius variable, and a function named getArea that
returns the area of the circle. The area is calculated as 3.14159 * radius * radius. Add a
default constructor to the Circle class, the constructor should initialize the radius member
to 0.
..........
2 . Add an overloaded constructor to the Circle class in question 1. The constructor should
accept an argument and assign its value to the radius member variable.
