Question

(Must be in C#)

(Console will be my choice)

Create a program called NarwhalCalc that will be used to compute a narwhal's weight in tons based on its length in feet. Your program must use a method to do this and you must write this method. Your method must be called FeetToTons and the method must accept a parameter called feet (type double). The method should then use the formula shown below to calculate the narwhal's weight, then RETURN (not output) that value.

weight in tons = feet * 0.075

So, a 20-foot narwhal would weigh 1.5 tons (20 * 0.075 = 1.5)

Summary of logic:

Have your Main() method prompt the user for a narwhal length, then PASS that value (as a parameter) to your FeetToTons method, then output the value RETURNED by your FeetToTons (note that it is Main that outputs the returned value -- FeetToTons should not output anything).

Be sure to use a named constant for the constant above.

Program can be console or GUI, your choice.

using System;

class NarWhalCalc {

    //the named constant

    const double multiplier = 0.075;

    public static void Main (string[] args){

        //prompts the user

        Console.Write("Enter the length in feet: ");

        //converts the input to double

        double feet=Convert.ToDouble(Console.ReadLine());

        //calls the method and stores it into variable

        double weight=FeetToTons(feet);

        //output

        Console.WriteLine("The weight is "+weight+" tons");

    }

    //METHOD

    static double FeetToTons(double feet){

        double weight=feet*multiplier;

        return weight;

    }
