寻找正方形和长方形的周长/周长的程序

图形的周长是所有边长之和。要计算正方形的周长，需要边长，因为所有边都相等。要计算矩形的周长，需要矩形的长和宽。
正方形的周长：

正方形的周长由以下公式给出：

C = 4 * a
where a is the side length.

例子 ：

input: 4
output: 16

input: 3
output: 12

C++

// CPP program to find
// Circumference of a square
#include 
using namespace std;
 
int Circumference(int a)
{
    return 4 * a;
}
 
// Driver Code
int main()
{
    int a = 5;
    cout << "Circumference of"
         <<" a square is "
         << Circumference(a);
    return 0;
}

    }
 
    // Driver code
    public static void main(String args[])
    {
        GFG obj = new GFG();
        int a = 5;
        System.out.println("Circumference of " +
                                "a square is " +
                          obj.Circumference(a));

Python3

# Python3 Program to find
# Circumference of a square
 
def Circumference(a):
        return (4 * a)
 
# Driver code
a = 5
c = Circumference(a)
print("Circumference of a " +
       "square is % d" % (c))

C#

// C# program to find Circumference
// of a square
using System;

{
 
    static int Circumference(int a)
    {
        return 4 * a;
    }
 
    // Driver Code
    public static void Main()
    {
        int a = 5;
 
        Console.WriteLine("Circumference" +
                       " of a square is " +
                         Circumference(a));
    }

Javascript

 
// Javascript program to find
// Circumference of a square
function Circumference(a)
{
    return 4 * a;
}
 
// Driver Code
    let a = 5;
    document.write("Circumference of"
        +" a square is "
        +Circumference(a));

输出 ：

Circumference Of a square is 20

长方形的周长：

矩形的周长由以下公式给出：

C = 2 * (l + W)
where l is the length and W is the width.

例子 ：

input: 2 4
output: 12

input: 4 6
output: 20

C++

// C++ Program to find
// Circumference of a rectangle
