Lab 9

COSC 1435 Lab 9

Purpose: This lab explores opening and using numeric data from a file.

Due: Before class on April 8, 2013

Requirements: Do the following:

1. Write a program that will do the following:

Open a disk file that contains an unknown number of integers. The file the grader tests with will have different numbers than the test files, but there will be white space between each number.
Read in each number from the file, one at a time, processing them as each is read in. The number you read in does not need to be saved after it has been processed. Here are three test files that you can use to test your program: integers1.txt, integers2.txt, integers3.txt
For these numbers in the file you will be doing the following:
- Print each number to the console, with a space in between each. Do not worry about line overflow.
- Counting the numbers in the file.
- Finding the sum of the number in the file.
- Find the high and low value in each file and the numeric position of each.
- Finding the average of all the numbers in the file.
When the end of file is reached, print a message that says "End of File".

To assist you in building this program, use the fileIn.cpp program I wrote in class. We will review this at the start of the lab.

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 or .docx 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.
Program source code (do not include the source code in the program documentation, only give the file name for the source code)
Program output, with sample data, from all three test files. The output must be from the clst.tamucc.edu Linux server, not from Windows.
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 lab09***.cpp, where the *** is replaced with your initials.
A copy of your program output saved as a file. This file should be called lab09***.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 lab09***doc.txt for a text file or lab09***doc.doc for a Microsoft Word file, where the *** is replaced with your initials.

Submit via blackboard following the instructions given during the lab.

Grading Criteria: 100 points available for this 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.
