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. 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 an appropriate message if the flight is not found. Farrell, Joyce. Microsoft Visual C#: An Introduction to Object-Oriented Programming (MindTap Course List) (p. 347).
