// Module Three Assignment
// 
// In later modules, you will begin to create class files to represent the items we have
// been using so far.  You will create class files for Students, Teachers, Courses, etc. 
// The class files will consist of attributes and methods.  To prepare for this, the
// assignment for this module will ask you to think about some basic methods that you can
// implement in your code.
// 
// This assignment requires you to create some methods for getting data for your variables
// and sending that data to the console window.
// 
// In the assignment, you are to practice getting values from a user and assigning the to
// local variables.  As a result, move the variables into the appropriate methods.  For
// example, you could create a method called GetStudentInformation() and in that method,
// you could prompt the user for each piece of student information and then assign it to
// the variables you created.
// 
// Next, create methods such as PrintStudentDetails(string first, string last, string
// birthday) that accepts the proper variables, and use an appropriate message to print
// the content to the console window.
// 
// The first example is a guide for you, the rest you will need to create on your own.
// 
// Create a method that prompts a user of your console application to input the
// information for a student:
// 
// static void GetStudentInformation()
// {
//       Console.WriteLine("Enter the student's first name: ");
//       string firstName = Console.ReadLine();
//       Console.WriteLine("Enter the student's last name");
//       string lastName = Console.ReadLine();
//        // Code to finish getting the rest of the student data
//       .....
// }
// }
// static void PrintStudentDetails(string first, string last, string birthday)
// {
//     Console.WriteLine("{0} {1} was born on: {2}", first, last, birthday);
// }
// }
// 1. Using the above partial code sample, complete the method for getting student data.
// 2. Create a method to get information for a teacher, a course, a uprogram, and a degree
// using a similar method as above.
// 3. Create methods to print the information to the screen for each object such as static
// void PrintStudentDetails(...).
// 4. From within Main(), call each of the methods to prompt for input from a user of your
// application.
// 5. Just enter enough information to show you understand how to use methods.  (At least
// three attributes each).
// 6. Assign the values that are input, to the proper variables.
// 7. Output the values of each object using the "print" methods that you created.
// 
// Exceptions
// 
// 1. At times, developers create method signatures early on in the development process
// but leave the implementation until later.  This can lead to methods that are not
// complete if a developer forgets about these empty methods.  One way to help overcome
// the issue of not remembering to complete a method is to throw an exception in that
// method if no implementation details are present. 
// 2. For this task, use MSDN to research the NotImplementedException exception.
// 3. Create a new method for validating a student's birthday.  You won't write any
// validation code in this method, but you will throw the NotImplementedException in this
// method
// 4. Call the method from Main() to verify your exception is thrown
// 
// Challenge (This challenge is for your own study and does not need to be submitted for
// peer review)
// 
// Using MSDN, research the System.DateTime type.  Using the information you learn, modify
// your birth date field for the student and/or teacher to ensure it used a DateTime type
// if you did not already include that in your data for these objects. 
// 
// Remove your NotImplementedException statement in the validate method you created above.
// Create a try/catch block to catch invalid date entries and display a message to the
// user if this occurs.  (Console output)
// Hint: Look at methods for DateTime to determine ways to check if a valid date is
// entered.
