Microsoft Visual C# 7th editionCreate 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.Here is my code, and I am having this error "1-Flights.GetFlightInfo(string, int[], string[], string[], string[])': not all code paths return a valueCompilation failed: 1 error(s)".For this line if (code != codes[x]) I am having error that string cannot be compared like this. How do we write a statement if 2 strings are not equal? 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) { 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"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 (code != codes[x]) return "Flight to {0} was not found."+ code; }}
