In the last homework you looked at the symbol table of your own compiled program. This
time we’ll be watching and interacting with precompiled programs as they execute.
Before you start, please make sure to log in systems[1-4].cs.uic.edu (e.g. systems1,
systems2, etc.).
The skeleton code for this assignment is available at this link. You must use GitHub
classroom to write your code and keep a commit log on GitHub. You will submit your files
via Gradescope.
Your task will be to fill out two files in your personal repository called secrets.txt and
howto.txt.
The format for secrets.txt should be:
0. these
1. are
2. not
3. real
4. secrets
howto.txt is also required: you must describe in English how to find the secret for that
given executable. Each individual howto should be on one more more lines after a line with
only the executable number and a period on it, like so:
0.

This was the really easy one. You had to run it and then type in the
secret of life.
1.
For this one, I had to:
* Run a specific unix utility to learn some specific information
* Perform some specific task that I found out about by checking part
of a specific line in the output of the unix utility.

Your howto.txt should enable any other CS 361 student to find the password within a
minute of reading it.
Warning
You must complete this assignment on systems[1-4].cs.uic.edu. Failure to do so will
result in a zero.
You will not be given any other files to complete secret findings except the 5 executable
files.
Hints:
Open your howto.txt alongside your shell as you work on each executable file, and use it
to take notes. If you don’t give a full description of how to arrive at the answer, you may not
receive points.
The content of lab section will be incredibly helpful for this assignment. If you miss it, ask
someone that went if they’re willing to share their notes with you.
Template
The executable files are available in the classroom repository and can be accessed using the
link above.
Turn-in instructions and Grading
Both secrets.txt and howto.txt must be submitted to Gradescope via GitHub. While
grading secrets.txt will be done automatically, the howto.txt will be graded by hand.
You should have both files in your submission. If you do not fill secrets.txt out exactly as
directed autograding will fail If you do not complete your assignment on any of
