Write a program that reads a list of enrollments from a file and prints a class roster for the teacher. Make the class roster line up as neatly as you can and still fit on the screen. You can choose the actual values to use for your data. Make sure to do enough sets of data to well test your program! (Empty data set, normal data set, data with large values, data with short values, etc.) Also, your program can't know ahead of time how many people are enrolled in the class... Don't forget to read the file's name from the user and protect your program against any errors that may occur during the opening of the file. Try to use functions to break up the program into more manageable pieces. USING C++ As an example, you might have the data file contain:

Variables and Constant

Constants and variables are widely used in mathematical equations and expressions. They are also commonly found in the domain of programming, where each language has its own way to differentiate between a constant and a variable. Since they have all sorts of applications, knowing their differences is a good place to start.
