He Saffir-Simpson Hurricane Scale classifies hurricanes into five categories numbered 1 through 5. Write an application named Hurricane that outputs a hurricane’s category based on the user’s input of the wind speed. Category 5 hurricanes have sustained winds of at least 157 miles per hour. The minimum sustained wind speeds for categories 4 through 1 are 130, 111, 96, and 74 miles per hour, respectively. Any storm with winds of less than 74 miles per hour is not a hurricane. If a storm falls into one of the hurricane categories, output This is a category # hurricane, with # replaced by the category number. If a storm is not a hurricane, output This is not a hurricane.

The program plan requires the design of the gui program form

Explanation:

The program plan will be as follows:

take 4 label and 4 text box and 1 button and modify the property of controls to design the gui form.

use 6 if statements and 1 else statement.

use or operator for comparison.

show message in textbox.

program code:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System. Data;

using System.Drawing;

using System.LINQ;

using System.Text;

using System.Threading.Tasks;

using System.Windows.Forms;

namespace...

Explanation:

namespace Hurricane

{

   public partial class Hurricane : Form

   {

       public Hurricane()

       {

           InitializeComponent();

       }

       private void btnSubmit_Click(object sender, EventArgs e)

       {

           //declare constants and variables

           const int CAT5 = 157, CAT4 = 130, CAT3 = 111, CAT2 = 96, CAT1 = 74;

           double WindSpeed = Convert.ToDouble(txtInput.Text);

           string Category;

           //determine hurricane category

           if (WindSpeed >= CAT5)

               Category = "a category 5 hurricane.";

           else if (WindSpeed >= CAT4)

               Category = "a category 4 hurricane.";

           else if (WindSpeed >= CAT3)

               Category = "a category 3 hurricane.";

           else if (WindSpeed >= CAT2)

               Category = "a category 2 hurricane.";

           else if (WindSpeed >= CAT1)

               Category = "a category 1 hurricane.";

           else

               Category = "not a hurricane.";

           //output

           lblOutput.Text = "A windspeed of " + WindSpeed + "mph is " + Category;

       }

       private void btnExit_Click(object sender, EventArgs e)

       {

           Application.Exit();

       }

   }

}

answer is c. complication
