More on editing and compiling

Compiling (inside emacs)
M-X compile
edit echo area to "gcc bug.c"
watch lower window
if you get error messages step thru' them with C-X ` and correct code
to get back into one window mode, type C-x 1
execute your program outside emacs (C-Z to put emacs to sleep, "fg" to wake it up)
finding errors:
in emacs: TAB key does indentation automatically
with gcc: "gcc loop1.c -Wall"
more on editing:
C-k deletes from cursor to end of line
C-y paste deleted text at current cursor position
"M-x line-number-mode"
access permissions
"ls -l"
"chmod u+rwx hello", g, o, a
x for directory means access for cd
homework
fizz-buzz
hw4.c as a starting point
