Create a program for Smalltown Regional Airport Flights that accepts either an integer flight number or string airport code from the options in Figure 8-33. Pass the user’s entry to one of two overloaded GetFlightInfo() methods, and then display a returned string with all the flight details. For example, if 201 was input, the output would be: Flight #201 AUS Austin Scheduled at: 0710 (note that there should be two spaces between 'Austin' and 'Scheduled'). The method version that accepts an integer looks up the airport code, name, and time of flight; the version that accepts a string description looks up the flight number, airport name, and time. The methods return a message if the flight is not found. For example, if 100 was input, the output should be Flight #100 was not found. If no flights were scheduled for the airport code entered, for example MCO, the message displayed should be Flight to MCO was not found. I am having these errors 1- Flights.GetFlightInfo(string, int[], string[], string[], string[])': not all code paths return a value Compilation failed: 1 error(s)". What does that mean and how will I fix it? 2- How to write a code to return a string? 3- What an overloaded method mean, and how to write it?

Create a program for Smalltown Regional Airport Flights that accepts either an integer flight number or string airport code from the options in Figure 8-33.

Pass the user’s entry to one of two overloaded GetFlightInfo() methods, and then display a returned string with all the flight details. For example, if 201 was input, the output would be: Flight #201 AUS Austin Scheduled at: 0710 (note that there should be two spaces between 'Austin' and 'Scheduled').

The method version that accepts an integer looks up the airport code, name, and time of flight; the version that accepts a string description looks up the flight number, airport name, and time.

The methods return a message if the flight is not found. For example, if 100 was input, the output should be Flight #100 was not found.

If no flights were scheduled for the airport code entered, for example MCO, the message displayed should be Flight to MCO was not found.

I am having these errors

1- Flights.GetFlightInfo(string, int[], string[], string[], string[])': not all code paths return a value
Compilation failed: 1 error(s)". What does that mean and how will I fix it?

2- How to write a code to return a string?

3- What an overloaded method mean, and how to write it? thank you.

Here is my code

using System;

using static System.Console;

class Flights

{

static void Main()

{

// Write your main here

int flight;

string flightCode;

int[] flightNumbers = {201, 321, 510, 633};

string[] codes = {"AUS", "CRP", "DFW", "HOU"};

string[] names = {"Austin", "Corpus Christi", "Dallas Fort Worth", "Houston"};

string[] times = {"0710", "0830", "0915", "1140"};

WriteLine("Enter flight number, the correct number are 201, 321, 510, 633");

flightCode = ReadLine();

flight = Convert.ToInt32(flightCode);

GetFlightInfo(flight, flightNumbers, codes, names, times);

}

public static string GetFlightInfo(int flight, int[] flightNumbers, string[] codes, string[] names, string[] times)

{

string flightNumber;

int x=0;

for(x=0; x > flightNumbers.Length; ++x)

{

if(flight==flightNumbers[x])

{

return "Flight # {0}{1}{2,2} Scheduled at: {3}" + flightNumbers[x] + codes[x]+names[x]+times[x];

}

else

WriteLine("Flight # {0} was not found", flight);}

flightNumber = Convert.ToString(flightNumbers[x]);

return flightNumber;

//return"Flight # was not found" + flight;

}

public static string GetFlightInfo(string code, int[] flightNumbers, string[] codes, string[] names, string[] times)

{

WriteLine("enter airport code; correct code are AUS, CRP, DFW, HOU");

code = ReadLine();

int x=0;

for(x=0; x> codes.Length;++x)

code.Equals(codes);

if(code.ToUpper().Equals(codes[x]))

return "Flight # {0}{1}{2,2} Scheduled at: {3}" + flightNumbers[x] + codes[x]+names[x]+times[x];;

if (String.Compare(code,codes[x])!=0)

return "Flight to {0} was not found."+ code;

}
