计算十边形周长的程序

给定方$S$十边形，任务是找出十边形的周长。
说明：在几何学中，十边形是一个十边形的多边形或十边形。规则的十边形所有边的长度相等，并且每个内角始终等于 144 度。

例子：

Input : S = 5
Output : The Perimeter of Decagon is : 50

Input : S = 8
Output : The Perimeter of Decagon is : 80

寻找十边形周长的公式是：

Perimeter = 10 * S

where "S" is the side of the Decagon

下面是求十边形周长的程序：

C++

// C++ program to Calculate the Perimeter of a Decagon
#include 
using namespace std;
 
// Function for finding the perimeter
void CalPeri()
{
    int s = 5, Perimeter;
 
    Perimeter = 10 * s;
 
    cout << "The Perimeter of Decagon is : "
                                << Perimeter;
}
 
// Driver code
int main()
{
    CalPeri();
 
    return 0;
}

C

// C program to Calculate the Perimeter of a Decagon
#include 
 
// Function for finding the perimeter
void CalPeri()
{
    int s = 5, Perimeter;
 
    Perimeter = 10 * s;
 
    printf("The Perimeter of Decagon is : %d",
                                    Perimeter);
}
 
// Driver code
int main()
{
    CalPeri();
 
    return 0;
}

Java

/*package whatever //do not write package name here */

{
    int S = 5, Perimeter;
 
    Perimeter = 10 * S;
 
    System.out.println("The Perimeter of Decagon is : "+
                                Perimeter);
}
 
// Driver code
    public static void main (String[] args) {
            CalPeri();
    }
}

Javascript

 
// JavaScript program to Calculate the Perimeter of a Decagon   
 
// Function for finding the perimeter
    function CalPeri() {
        var S = 5, Perimeter;
 
        Perimeter = 10 * S;
 
        document.write("The Perimeter of Decagon is : " + Perimeter);
    }
 
    // Driver code
     
        CalPeri();

输出：

The Perimeter of Decagon is : 50
