CSCI 216 Spring 2015

Project #1

Date Due: 26 January 2015

Purpose: to review the C you learned in 116 and to refamiliarize yourself with how to use Visual Studio

Program objective: This program is to do some simple file processing.

Instructions: Write a simple C++ program to ask the user for a file name. Open the file and read the first and the last number in the file. Print the two numbers, and then print the average of the two numbers. Sample output might look like:

What file should I use? data1.txt

There are 10000 numbers in the file

The first number is 195650

The last number is 887747

The average of the two is 541698.5

Press any key to continue

Append the output to the end of the program source as a comment, print out the resultant program listing, and turn it in by class time on the due date. Sample data files to try include dat1a.txt, data1.txt, data2.txt, and data3.txt.

You should check to make sure that the file opened properly, and exit printing an error message if it didn’t. You should also remember to close the file when you are done reading from it.
