Write a complete C++ program in one file here that asks the user to enter a radius for a circle then calculates and prints its' area. The area should be calculated using the formula area = 3.14 * radius * radius. You must have a class called Circle that stores the radius as a double value and can calculate its' own area via a method called calcArea that takes no parameters and returns the area. The circle class may not print the area or radius! Hint: calcArea should take no parameters and return a double. For this version, make radius public and use the dot operator to store and retrieve its' value. Do NOT worry about input validation for this version. Upload as circlePublic.cpp.

Object Oriented Programming System (OOPs) is a programming model built on the perception of “objects” that contains data and methods. The major purpose of Object Oriented Programming is to increase the maintainability and flexibility of programs. Object Oriented Programming gets together data and its behavior (methods) in a single location (object) which makes it easier to understand.
