This week in lab you should have them write the following program:

Write a program that given the name of a file and a string to search
for, determines whether the search string occurs in the file.  If not,
print out an appropriate message.  If the string occurs in the file,
for each line that the word appears on, the program should output a
copy of the line followed by a line with blanks and dashes that
"underline" the occurrence of the search string.

For example:

The file contains the following:

Hello, this is a file that was
created to test the lab that is
to be done in lab this week.

and the search word is: "that"

the output would be:

Hello, this is a file that was
                      ----
created to test the lab that is
                        ----


They should have this checked off during the lab.  Also, they will
probably have a lot of questions about the assignment.  You should
try and help them with this.  I know some are still having problems
with the random number generator.  Maybe you should explain this some
more.  


Other things:
Tell them that they are supposed to turn in all programs (for labs and
assignments) in Unix format from now on.

Also, can you get a list of their logins.  I would like to be able to
send them email.

Could you also show them how to use makefiles with more than one
file.  They are going to be having to split their programs up into
more than one file soon.  You can just go over this briefly if you
want, and then when they have to start splitting their programs up,
you should remember to go over it again more thoroughly.
