Please type 1 for First Class and Please type 2 for Economy

Question

(Airline Reservations System) A small airline has just purchased a computer for its new automated reservations system. You have been asked to develop the new system. You are to write an application to assign seats on each flight of the airline's only plane (capacity: 10 seats).
Your application should display the following alternatives: Please type 1 for First Class and Please type 2 for Economy. If the user types 1, your application should assign a seat in the first-class section (seats 15). If the user types 2, your application should assign a seat in the economy section (seats 610).
Use a one-dimensional array of simple type bool to represent the seating chart of the plane. Initialize all the elements of the array to false to indicate that all the seats are empty. As each seat is assigned, set the corresponding element of the array to True to indicate that the seat is no longer available.
Your application should never assign a seat that has already been assigned. When the economy section is full, your application should ask the person if it is acceptable to be placed in the first-class section (and vice versa). If yes, make the appropriate seat assignment. If no, display the message "Next flight leaves in 3 hours."

This question doesn't make sense as it says the plane's capacity is only 10 seats yet there are 15 first-class seats and 610 economy seats! Anyway this assumes the capacity is 625 seats: using System; class Program { static void Main() { // elements 0 to 14 first class // elements 15 to 624 economy class bool[] isReserved = new bool[625]; for(int i = 0; i while(true) { int number; Console.Write(Please type 1 for First Class and Please type 2 for Economy: ); int.TryParse(Console.ReadLine() out number); if (number == 1) { if(!isReserved[14]) // there are still seats in first-class { for(int i = 0; i { if (!isReserved[i]) { isReserved[i] = true; break; } } } else // first-class is full { while(true) { Console.Write(First-class section is full. Is economy section acceptable instead y/n: ); string yn = Console.ReadLine().ToLower(); if (yn == y) { if(!isReserved[624]) // there are still seats in economy class { for(int i = 15; i { if (!isReserved[i]) { isReserved[i] = true; break; } } break; } else { Console.WriteLine(Sorry the economy section is full too. Next flight leaves in 3 hours.); return; } } else if (yn == n) { Console.WriteLine(Next flight leaves in 3 hours.); break; } else { Console.WriteLine(Please answer y or n); } } } } else if (number == 2) { if(!isReserved[624]) // there are still seats in economy class { for(int i = 15; i { if (!isReserved[i]) { isReserved[i] = true; break; } } } else // economy class is full { while(true) { Console.Write(Economy class section is full. Is first-class section acceptable instead y/n: ); string yn = Console.ReadLine().ToLower(); if (yn == y) { if(!isReserved[15]) // there are still seats in first-class { for(int i = 0; i { if (!isReserved[i]) { isReserved[i] = true; break; } } break; } else { Console.WriteLine(Sorry the first-class section is full too. Next flight leaves in 3 hours.); return; } } else if (yn == n) { Console.WriteLine(Next flight leaves in 3 hours.); break; } else { Console.WriteLine(Please answer y or n); } } } } else { Console.WriteLine(Please enter 1 or 2); } } } }
