C++ Exercises: Print the area of a hexagon

Sample Solution:

C++ Code :

#include <iostream> // Including input-output stream header file
#include <math.h>   // Including math functions header file

using namespace std; // Using the standard namespace

int main() { // Start of the main function

    float ar, s; // Declaration of variables 'ar' and 's' to store area and side length respectively

    cout << "\n\n Print the area of a hexagon:\n"; // Displaying the purpose of the program
    cout << "---------------------------------\n";
    cout << " Input the side of the hexagon: "; // Prompting user to input side length
    cin >> s; // Taking input from user and storing it in variable 's'

    // Calculating the area of the hexagon using the formula: 6 * s^2 / (4 * tan(π/6))
    ar = (6 * (s * s)) / (4 * tan(M_PI / 6)); // M_PI represents the value of π

    cout << "The area of the hexagon is: " << ar << "\n"; // Displaying the calculated area

    return 0; // Returning 0 to indicate successful program execution
}

Sample Output:

 Print the area of a hexagon:                                          
---------------------------------                                     
 Input the side of the hexagon: 6                                    
The area of the hexagon is: 93.5307
