Struggling with basic errors C#

Hi all,

I'm very new to C# and I've currently just 'completed' a bit of code however I've been left with 7 errors that I can't seem to get rid of!

Here is my code - I realise it is very basic and apologies if I have not provided all the information. Like I said, I'm new :)

All errors are in bold.

namespace _250213

{

class Journey

{

private string JourneyDate;

private string JourneyStart;

private string JourneyEnd;

private string JourneyDistance;

private string JourneyFuelUsed;

private string JourneyPurpose;

public Journey(string JourneyDate, string JourneyStart, string JourneyEnd, string JourneyDistance, string JourneyFuelUsed, string JourneyPurpose)

{

JourneyDate = date;

JourneyStart = start;

JourneyEnd = end;

JourneyDistance = distance;

JourneyFuelUsed = fuelused;

JourneyPurpose = purpose;

//lists all the components i'm going to have for the Journey

}

public string TellMe()

{

return "Journey #" + (+1) + "was on" + JourneyDate + "."

+ " The journey started on " + JourneyStart + "."

+ " It ended on " + JourneyEnd + "."

+ " It was " + JourneyDistance + "miles."

+ " The fuel used was" + JourneyFuelUsed + "gallons."

+ " The purpose of this particular journey was " + JourneyPurpose + ".";

} //this is what it going to be outputted by the app once the user has submitted all the information. The + JourneyColour etc is where the users informaiton

}

class Program

{

static void Main(string[] args)

{

int numJourneys;

String response;

String JourneyDate;

response = Questions(response, out numJourneys, out JourneyDate, out JourneyStart, out JourneyEnd, out JourneyDistance, out JourneyFuelUsed, out JourneyPurpose); //gives full information about the Journey

Journey[] myJourneyArray = new Journey[numJourneys];

for (int i = 0; i < myJourneyArray.Length; i++)

{

myJourneyArray[i] = new Journey(JourneyDate + i.ToString(), JourneyStart + i.ToString(), JourneyEnd + i.ToString(), JourneyDistance + i.ToString(), JourneyFuelUsed + i.ToString(), JourneyPurpose + i.ToString());

}

for (int i = 0; i < myJourneyArray.Length; i++)

{

Console.WriteLine(myJourneyArray[i].TellMe());

}

Console.ReadLine(); //array to store the Journeys in

}

private static string Questions(String response, out int numJourneys, out String Journeydate, out String Journeystart, out String Journeyend, out String JourneyDistance, out String JourneyFuelUsed, out String JourneyPurpose)

{

Console.WriteLine("How many Journeys are there? "); //asks the question

response = Console.ReadLine(); //reads the response given

} while (!int.TryParse(response, out numJourneys));

Console.Write("What is the model of Journey #" + (+1) + "? "); //asks question

Journeydate = Console.ReadLine(); //reads input from user

Console.Write("What is the colour of Journey #" + (+1) + "? ");

Journeystart = Console.ReadLine();

Console.Write("What is the engine size of Journey #" + (+1) + "? ");

Journeyend = Console.ReadLine();

Console.Write("What is the fuel type of Journey #" + (+1) + "? ");

JourneyDistance = Console.ReadLine();

Console.Write("What is the mileage of Journey #" + (+1) + "? ");

JourneyFuelUsed = Console.ReadLine();

Console.Write("What is the nickname of Journey #" + (+1) + "? ");

JourneyPurpose = Console.ReadLine();

Journey myJourney = new Journey(Journeydate, Journeystart, Journeyend, JourneyDistance, JourneyFuelUsed, JourneyPurpose);

string[] myStringArray = new string[5];

Console.WriteLine(myJourney.TellMe());

Console.ReadLine();

return response; //the output from all the questions given

}

} //method of the string questions

}

Here are my requirements, please note I am only doing the first two bullets points to start with to see if I can get that working.

? Log a new journey that includes the following details:

o Date of journey

o Start Location

o End Location

o Distance (in miles)

o Amount of fuel used (in gallons)

o Purpose of Journey

? Output a list of journeys that have been entered so far

? Get a detailed on-screen report for a particular journey– The output should include a

calculated fuel economy from the distance travelled and the fuel used.

? Get a tabular report of all journeys that have been entered. Each journey should be a row in

the output – which should be formatted appropriately. An average fuel economy should be

calculated for all journeys in addition to the economy of each individual journey.

Regards,

Joe

I've corrected the errors below so that it will now compile and you can proceed to the next stage:
