The condition that controls a Do While loop must be true for the loop to be executed. Checkboxes are used in designing the user interface for situations where the user may choose only one of a few choices. Boolean variables are often used to improve the readability / clarity of the program code. For Next loops can have both negative and positive step values. If no item has been selected in a listbox, the SelectedIndex property of the listbox will have a value of zero. A Boolean variable must be initialized after the If instruction in which it is used is executed. A post-test loop is a loop that is designed to be executed at least once. In coding a Select Case instruction, the only thing that may appear after the Select Case keywords is a variable. A Do loop begins with the keyword Do and ends with the keyword Loop.

Microsoft Visual C# 7th edition 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-…
