+Ok, now you've been walked through editing, saving,
+and submitting an assignment.  For this assignment, we're just going
+to have you practice that on your own before
+we move on to things involving writing code.
+
+- Create a file called "fruit.txt"
+- Write one line, containing the text
+apple
+into that file
+- Save the file and submit the assignment for grading

+Open the code1.c file you have in this directory.
+You will see two functions:  max and main.
+
+In max, the algorithm is written as comments, but there is no code.
+You should translate this algorithm to code.
+
+In main, there are three print statements which call max and print
+its result.  These would let you check if max is working right.
+
+There is also a comment asking you to write one more print statement
+with a call to max.  In that comment, it asks you to take the max
+of two numbers (written as hex), and print them out.
+Add a line of code to do this.
+
+When you have done this, run
+
+./test.sh
+
+This script will try to compile your code (which you will learn about in
+the next chapter), as well as run it.   If your code does not have legal
+syntax, it will do its best to describe what is wrong.  If there
+is a problem, look at the code and try to see where you did not follow
+the syntax rules from chapter 2.  The line number and message it gives
+may help you find the problem.  If you cannot find the problem after a minute
+or two, ask for help.
+
+If your code has legal syntax, test.sh will also run it, and show
+you the output it produced, as well as the output we expected.
+
+If they are the same, you should commit, push, and grade.
+
+If they are not, you should see if you can fix the problem (and ask for help
+if you cannot).
