Help write the code for the follwing problem starting from scratch Write a complete C++ program in three files 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 private and write setter (mutator) and getter (accessor) methods and/or constructors as needed to modify (set) and retrieve (get) the value of radius. Input Validation: If a negative radius is passed to an object of the Circle class, whether through a setter or a constructor, set the radius to 0 instead of using the negative value. This program MUST be split into three files: Header file for the circle class, implementation file for the circle class, and implementation file for main. Hint: This program does the same thing as the one in the previous question. Upload as circle.h, circle.cpp and circleMain.cpp.

Help write the code for the follwing problem starting from scratch

Write a complete C++ program in three files 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 private and write setter (mutator) and getter (accessor) methods and/or constructors as needed to modify (set) and retrieve (get) the value of radius. Input Validation: If a negative radius is passed to an object of the Circle class, whether through a setter or a constructor, set the radius to 0 instead of using the negative value. This program MUST be split into three files: Header file for the circle class, implementation file for the circle class, and implementation file for main. Hint: This program does the same thing as the one in the previous question. Upload as circle.h, circle.cpp and circleMain.cpp.
