You can some mistakes in your code:
The first mistakes in line - 'kill(getpid(),-9);'
In the Unix basic systems have not a signal with id '-9', but have a signal with id '9'.
Try with int k=kill(getpid(),SIGKILL);
The second mistakes is similar that first - 'int r=raise(-9);' .
The third mistakes:
You don't kill process whit 'raise', because process one killed from 'k=kill(getpid(),SIGKILL);'
Do you really need killing a current process ?

KILL(1) General Commands Manual KILL(1)
NAME
kill - terminate a process with extreme prejudice
SYNOPSIS
kill [ -sig ] processid ...
kill -l
DESCRIPTION
Kill sends the TERM (terminate, 15) signal to the specified processes. If a signal name or number preceded by `-' is given as first argu-
ment, that signal is sent instead of terminate (see sigvec(2)). The signal names are listed by `kill -l', and are as given in
/usr/include/signal.h, stripped of the common SIG prefix.
The terminate signal will kill processes that do not catch the signal; `kill -9 ...' is a sure kill, as the KILL (9) signal cannot be
caught. By convention, if process number 0 is specified, all members in the process group (i.e. processes resulting from the current
login) are signaled (but beware: this works only if you use sh(1); not if you use csh(1).) Negative process numbers also have special
meanings; see kill(2) for details.
The killed processes must belong to the current user unless he is the super-user.
The process number of an asynchronous process started with `&' is reported by the shell. Process numbers can also be found by using ps(1).
Kill is a built-in to csh(1); it allows job specifiers of the form ``%...'' as arguments so process id's are not as often used as kill
arguments. See csh(1) for details.
SEE ALSO
csh(1), ps(1), kill(2), sigvec(2)
BUGS
A replacement for ``kill 0'' for csh(1) users should be provided.
