Just look at them in the debugger:

$ gdb ./foo
GNU gdb [... blah blah blah ...]
(gdb) b main
Breakpoint 1 at 0x8048433: file foo.c, line 6.
(gdb) r
Starting program: ./foo 
Breakpoint 1, main (argc=1, argv=0xbffff584, envp=0xbffff58c) at foo.c:6
(gdb) p argv[0]
$1 = 0xbffff698 "./foo"
(gdb) p envp[0]
$2 = 0xbffff6ad "VISUAL=/usr/bin/emacs"
(gdb) p envp[31]
$3 = 0xbfffffd9 "HISTSIZE=1000"

et cetera, et cetera ...
