You will need to use <tt>ssh</tt> to connect to <tt>newcunix.cc.columbia.edu</tt> as described in the first class session.
You can find information on CUNIX accounts <a
href="http://www.columbia.edu/acis/publications/handouts.html">here</a> and
<a href="http://www.columbia.edu/acis/tools"> here </a> and
and you can find a list of <tt>ssh</tt> programs 
<a href="http://www.columbia.edu/acis/software/terminal.html">here</a>.

<p>On your CUNIX account you will need to create a directory for you
homework assignment.  You can do this by running a command such as:

<p><tt>mkdir hw1</tt>

<p>Change into this directory (by running <tt>cd hw1</tt>) and create
your programs here.  You can edit your programs with any of the
available editors (emacs, vi, pico), emacs is recommended.  
You may want to consult the <a
href="http://www.columbia.edu/acis/webdev/unix/index.html">quick guide
to UNIX</a> and the <a
href="http://www.columbia.edu/acis/publications/emacs.html">quick
guide to Emacs</a> if you run into any problems.

<p>Your programs should all have the extension ".cc".  
Use <tt>g++</tt> as the compiler for this homework, if you prefer to use <tt>CC</tt> you may do so, but be sure to note this in your README.  
You should compile your programs with the following command:

<p><tt>g++ -Wall program.cc</tt>

<p>The <tt>-Wall</tt> forces display of warnings in addition to errors.  This will
generate an executable named a.out.  If you want your executable to be
named something else, run something like this:

<p><tt>g++ -Wall program.cc -o program</tt>

<p>The <tt>-o</tt> option allows you to specify the name of the executable.
To run your programs you will likely have to run them like this:

<p><tt>./a.out</tt>

<p>or

<p><tt>./program</tt>

<p>since the current directory isn't by default included in your PATH (and shouldn't ever be unless you like having hackers take over your machine).
