Concept explainers

Class

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.

Question

I need help in understand the codes used in this C++ program. I would also like to know its purpose

#include<iostream>
#include<cmath>
#include <iomanip>
#define PI 3.1416 //define the constant value of PI
using namespace std; //std namespace
int main() //main function
|{
float n, s; //declaration of variable
Enter number of sides of the polygon: " ; //display the number of sides
cout <<
cin >> n; //input of the number of sides
cout « " Enter length of each side of the polygon:
cin >> s; //input of the length of each sides
; //display the Length of each sides
float perimeter; //declaration of variable
perimeter = n*s; //equation of perimeter
float area; //declaration of variable
area = ((n * (s*s)) / (4.0 * tan(PI/ n))); //equation of area
cout « " Perimeter is : "<<fixed<<setprecision(4)<<perimeter<<"\n" ; //print the perimeter of the polygon
%3D
Area is : "<<fixed<<setprecision(4)<<area<<"\n" ; //print the area of the polygon
cout <<
return 0; //return
- } //end program

A regular polygon has n number of sides with each side of length s. The area of a regular polygon is given by:
ns?
A =
4 tan
The perimeter of a polygon is equal to the length of the boundary of the polygon
Write a C++ program that will output the area and the perimeter of a given regular polygon rounded-off to four
decimal places.

Process by which instructions are given to a computer, software program, or application using code.
