Description
EE 2372 Assignment 6
Objectives:
1) Learn to read and use command line arguments
2) Learn to dynamically allocate memory using malloc
3) Learn to read binary data from a file
Description
In this programming assignment you will write a program that reads binary data from a
file. The first value in the file is an integer that indicates the number of floating point
values remaining in the file. The remaining data is the actual floating point values. Your
program must do the following:
1. The name of the input file is to be passed into the program as a command line
argument.
2. The program will open this binary file, and read the first integer in the file. It will
then dynamically create an array of floats of this size using the malloc function.
3. The program will then read the floating point values and store them into this
newly created array.
4. Finally, the program will print out the floating point values in this array in reverse
order, one value per line.
Files data1 and data2 are now on the course web site. The file data1 contains the
following:
4, 1.1, 2.2, 3.3, 4.4
The output from your program ($./a.out data1 or $binread data1) should give
4.400000
3.300000
2.200000
1.100000
EE 2372 Assignment 6
Deliverables:
1) The output produced by file data2 as an attachment. Name the file data2out.txt
2) The C source code as an attachment. Name the file binread.c
3) Mail the requested files to our TA Pavithra Pochamreddy at
ppochamredd@miners.utep.edu.
4) The subject line must be “EE 2372 Assignment 6” (don’t include the quotes).
Scoring:
Your grade for this assignment will be determined by three criteria. The first criterion
determines if your program compiles and runs producing the correct result. The correct
result must adhere to what is specified in the Tasks section. The second criterion is
whether the program follows the interface specification outlined in the Tasks section.
The
third criterion determines if your source code is well documented. Your source code must
include (at the top) your name, class section, due date, assigned date, and a small
description of your program. For this assignment, each line of code should have a
descriptive comment.
Operation/Successful Demonstration 60%
Was a C source file submitted? 10%
Does the program compile on Linux? 15%

Adherence to Interface Specification 30%
Does the program adhere to the interface specification
in the tasks section? 30%
Comments 10%
Is the source code well-documented? 10%
Lateness 10% per day (including
weekends and holidays)
