Here are the two programs which you may choose from to do this program:
1. Using Files - Student Line Up
Modify the Student Line Up program described in Programming Challenge 14 which
states:
"A teacher has asked all of her students to line up according to their first name. For
example, in one class Amy will at the front of the line, and Yolanda will be at the end.
Write a program that prompts the user to enter the number of students in the class, then
loops to read that many names. Once all of the names have been read, it reports which
student would be at the front of the line and which one would be at the end of the line.
You may assume that no two students have the same name.
You are now to do this program reading names from a file. Names should be read in
until there is no more data to be read. I am providing for you a file named LineUp.txt
for you to use in writing this program.
I suggest that you write it first without the file and then modify to add the file.
