That's the correct and expected behaviour, as the "%" character
is not part of the command you should enter. It's the shell's prompt
character shown to illustrate that the command should be entered from
a user account (in opposite to the root account where "#" is used).
You will see this way of "implicit documentation" in many places.

It's the same, except on Ubuntu you'll probably see a "$" infront of
command line examples.

Do not enter the "%" character, just the command. To illustrate:

	% cc filename.c
	% ./a.out

or

	% cc -o myprog filename.c
	% ./myprog

Note that the "./" is needed infront of the program name you just compiled
because the current working directory usually is not in $PATH, so the shell
will not execute programs from that location unless explicitely specified.
