计算对角线给定的菱形的面积和周长的程序

给定菱形对角线的长度，d1 和 d2。任务是找到那个菱形的周长和面积。
菱形是有4条等边的多边形，其中对边平行，对角相等。

例子：

Input: d1 = 2 and d2 = 4
Output: The area of rhombus with diagonals 2 and 4 is 4.
        The perimeter of rhombus with diagonals 2 and 4 is 8.

Input: d1 = 100 and d2 = 500
Output: The area of rhombus with diagonals 100 and 500 is 25000.
        The perimeter of rhombus with diagonals 100 and 500 is 1019.

Area of the rhombus = $\frac{1}{2} (d1 * d2)$
Perimeterof the rhombus = $2\sqrt{(d1)^2+(d2)^2}$

下面是上述方法的实现：

C++

// C++ Program to calculate area and perimeter
// of a rhombus using diagonals
#include 
#include 
using namespace std;
 
// calculate area and perimeter of a rhombus
int rhombusAreaPeri(int d1, int d2)
{
    long long int area, perimeter;
 
    area = (d1 * d2) / 2;
    perimeter = 2 * sqrt(pow(d1, 2) + pow(d2, 2));
 
    cout << "The area of rhombus with diagonals "
         << d1 << " and " << d2 << " is " << area << "." << endl;
 
    cout << "The perimeter of rhombus with diagonals "
         << d1 << " and " << d2 << " is " << perimeter << "." << endl;
}
 
// Driver code
int main()
{
 
    int d1 = 2, d2 = 4;
    rhombusAreaPeri(d1, d2);
 
    return 0;
}

    area = (d1 * d2) / 2;
    perimeter = (int)(2 * Math.sqrt(Math.pow(d1, 2) + Math.pow(d2, 2)));
 
    System.out.println( "The area of rhombus with diagonals "
        + d1 + " and " + d2 + " is " + area + ".");
 
    System.out.println("The perimeter of rhombus with diagonals "

        return 0;
}
