I need some help with this weeks code. This is what was asked.

This week, you will optimize the existing project code by implementing methods. Additionally, you will test the code for non-permissible input value(s) of the variable(s) and document your test results. Improve your code by adding a statement that displays an error message.

I have the following, where do I go from here?

This is in C#, it would not let me select that as a subject.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace AviationQuiz

{

//Create the class.

class Quiz

{

//Define the main method.

static void Main(string[] args)

{

//Introduction Text

Console.Title = "Aviation Quiz";

Console.WriteLine("Created by Kory Stanfill");

Console.WriteLine("Aviation Questions");

Console.WriteLine("ENGR 115: Checkpoint 2"); ;

//Create the Questions

string[] questions ={"You pitch up in an airplane that has a balance tab on its elevator. Which way does the tab move??"

,"You're flying a Piper Cherokee. If your alternator fails in cruise flight, your engine will continue running."

,"You're preflighting a Cessna 172 and you see this hole on the side of the cowl. What is it?"

,"What changes the prop's pitch on this constant speed propeller hub?"

,"Air temperature heats up as it passes through the Venturi of a carburetor."

,"An aircraft with an aft CG requires what than the same aircraft with a forward CG?"

,"Which of these factors has the greatest effect on density altitude?"

,"A single engine aircraft at max gross weight will have a climb rate of _______ at its service ceiling."

,"You're flying a cross country from an area of high pressure to an area of low pressure. If you don't reset your altimeter, your plane will be lower than the indicated altitude on your altimeter."

,"An aircraft in a constant altitude, 60-degree bank turn has a load factor of what?"};

Boolean[] status = { false, false, false, false, false, false, false, false, false, false };

//Create the Answers
