This program relies on a series of data files. Simply right-click on the links below (control-click on a Mac) and select Save-As to save these files to your computer. Ensure that these files are stored in a folder that contains your source code file

• class_data.txt
• enrollment_data.txt

class_data.txt

Stores the course ID and the title of each course. There will always be one record in this file for every course that the CS department is currently offering. Here’s what this file looks like:

CS0002,Introduction to Computer Programming

CS0004,Introduction to Web Design and Computer Principles

CS0060,Database Design and Implementation

CS0061,Web Development

CS0101,Introduction to Computer Science

CS0102,Data Structures

CS0201,Computer Systems Organization

CS0380,Special Topics in Computer Science

enrollment_data.txt

Stores the course ID, last name and first name of each student enrolled in the course. Note that there are multiple records per course (one per student enrolled). For example, here’s the beginning of this file showing six students enrolled in CS0002:

CS0002,Hiner,Judith

CS0002,Mcmahon,Ludivina

CS0002,Trusty,Beatrice

CS0002,Brinn,Jacqulyn

CS0002,Hintzen,Floria

CS0002,Amyx,Randolph

Your task is to write a program that asks the user for a course ID. The program will then determine if the course ID is valid or not — if it is not, the program can safely end. If it is valid, the program should report the full title of the course, how many students are enrolled in the course and the names of each student enrolled.

You cannot hard code your program to only work with the values contained within these files. When we test your work we will be using completely different data files that are organized in the same way as these sample files. Your program should work flawlessly using this new data.

I’ve broken up this program into smaller tasks that you should attempt one at a time as a group. Do these in order.

Task #1

• Begin by asking the user for a course.
• Next, open the file class_data.txt for reading and obtain all data from the file.
• You’ll need to parse this file so you can access the data you care about. Take a look at how the file is being organized:COURSE_NUMBER_1,COURSE_DESCRIPTION_1 COURSE_NUMBER_2,COURSE_DESCRIPTION_2 COURSE_NUMBER_2,COURSE_DESCRIPTION_2
• Each line contains information about a course. On each line you have two values to work with – the course number and the course description. These values are separated by commas.
• The first step is to isolate the individual lines from one another.
• Hint: the split method may be useful here!
• After this, you need to examine each line and identify if that line contains the course number that the user typed in. This will require you to isolate the course number from the course description.
• Hint: a for loop along with another call to the split method may be useful here!
• Store the title somewhere (an accumulator variable?) so you can access it later.
• Finally, generate some output to let the user know if (a) the course cannot be found or (b) the course can be found, along with the title. Do this outside of the loop that you used to find the course. Hint: you may need to set a variable to indicate that you found the course, along with the course title to do this.

At the end of task #1 your program should operate as follows:

Enter a course: pikachu

That course is not running this semester

Enter a course: CS

That course is not running this semester

Enter a course: CS0002

The title of this class is: Introduction to Computer Programming

Task #2

Next you will need to see how many students are enrolled in the course (if it exists). Here’s how to get started:

• If the course is running you will need to open up the enrollment_data.txt file and read in the contents of this file as a string.
• This file is organized as follows:COURSE_NUMBER,STUDENT_LAST_NAME,STUDENT_FIRST_NAME COURSE_NUMBER,STUDENT_LAST_NAME,STUDENT_FIRST_NAME COURSE_NUMBER,STUDENT_LAST_NAME,STUDENT_FIRST_NAME COURSE_NUMBER,STUDENT_LAST_NAME,STUDENT_FIRST_NAME
• Each line contains information about a student. On each line you have three values to work with – the course number, the last name of the student and the first name of the student. These are all separated by commas.
• Begin by isolating the individual records from one another (the lines). Then examine each line to see if that line contains a student enrolled in the desired course.
• When examining a line of data you will need to further process that line it (to extract the course number and the student name)
• If that line contains the course number in question you should make a note of it. Hint: an accumulator list may be useful to store all of the students enrolled in this course.
• Finally, after you’ve finished examining each line you should print out your final report (how many students are enrolled and each of their names)

At the end of task #2 your program should operate as follows:
