Lab 12

COSC 1435 Lab 12

Purpose: This lab gives the student practice in working with file data, using arrays, and calling functions.

Due: Before class on April 29, 2013

Requirements: Do the following:

1. This program opens a disk file that contains student names and grades. Each student will have 12 grades. Do the following:

Open the disk file and verify it opened properly (you may use the functions you developed for earlier labs to accomplish this). Read in each line of the data file, then process each line. The information on each line of the data is space delimited (you can use the file handle and the input operator ('>>') to read the data). Store the name in two strings and the grades in an array of 12 integers. Here is the data file: lab12Data.txt

Print a report that shows for each student the student's name (each student will have a first and a last name), their average for the 12 grades, their high grade, their low grade, and their median grade. This report should be in columns, with appropriate column headers.

There must be a separate function that determines the average grade, the high grade, the low grades, and the median grade. Use the sortArray function from program from Gaddis to sort your data for the median calculation (remember to properly attribute the sort program). All of these functions must be written to take in an array of integers of any size and to return a value to the calling program, as was demonstrated in class.

After all the students have been processed, write out a report that shows the class average for each of the 12 grades. To do this you need to total all of the student grades on assignment 1, then find the average for that assignment. Repeat for each assignment.

2. This lab requires a lab report/documentation package. All of these items are not typically in the same file (source code and sample output should definitely be in their own files), but the main lab report file must reference each item by file name. Here is a sample lab report. The main lab report must either be a text file (with a .txt extension) or a Microsoft Word file (with a .doc extension). The lab report must includes the following or references (the file name that was attached to the mail) to the following information:

Your Name
Purpose of this program.
Pseudocode
Program source code
Program output, with sample data.
How was this program tested, including the test values you put into the program to verify that it worked properly for all types of cases within the program specifications.
What problems/successes did you have with this program?
An estimate of how much time you spent working on this lab

Program Submission. You will be submitting this lab via Blackboard. The teaching assistant will provide further instructions on how to accomplish this. Prepare the following:

Your program source code. This file should be called lab12***.cpp, where the *** is replaced with your initials.
A copy of your program output saved as a file. This file should be called lab12***.txt, where the *** is replaced with your initials. The .txt signifies that this is an ASCII text file.
A lab report as described above. The lab report may be in a Microsoft Word document, with a .doc suffix or an ASCII text file with a .txt suffix. Make sure it contains all of the required items. This file should be called either lab12***doc.txt for a text file or lab12***doc.doc for a Microsoft Word file, where the *** is replaced with your initials.

Submit via blackboard following the instructions given during the lab.

The lab will be graded using this grading criteria. The points will then be scaled to the available points.

Here is a C++ style guide from Dr. Fernandez that should assist you in coding your program. Style guide.

100 points if all of the above requirements are met.
