In Class: Week 1, Thursday

In your cs21 subdirectory create a directory named week1, and cd into that directory:

% cd            # make sure you are in your home directory
% ls		# list the contents of your home directory
   cs21/	# should be a single directory that we created last time
% cd cs21       # change directories to cs21
% pwd		# check that you are in your /home/username/cs21 sub directory

% mkdir week1   # make a new directory named week1 in your cs21 directory 	
% cd week1
% pwd		# check that you are in your /home/username/cs21/week1 sub directory

Now copy over all the files from my public/cs21/week1 directory into your week1 directory:

% cp ~newhall/public/cs21/week1/* .
% ls

We are going to start by looking at the add.c program together, so go ahead and open it in one of emacs, vi, vim, or gvim:

% emacs add.c  

% vi add.c

% vim add.c                 # vim and vi are the same editor

% gvim add.c                # gvim is the graphical version of vim

To compile and run the add.c program:

% gccx add.c                # compile add.c to create an executable file a.out 
% ls
  a.out*    add.c
% ./a.out	            # to run the a.out file

Later, you will open the TODO file in emacs (or vi) and follow the instructions.
