In this lab, you complete a partially pre$-$written Java program that includes a function with no parameters.

The program asks the user if they have preregistered for art show tickets. If the user has preregistered, the program should call a function named discount$()$ that displays the message "You are pre$-$registered and qualify for a $5\%$ discount." If the user has not preregistered, the program should call a function named noDiscount$()$ that displays the message "Sorry, you did not pre$-$register and do not qualify for a $5\%$ discount."

The source code file provided for this lab includes the necessary variable declarations and input statement. Comments are included in the file to help you write the remainder of the program.
