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 ?
Best regards,

RAISE(3) Linux Programmer's Manual RAISE(3)
NAME
raise - send a signal to the caller
SYNOPSIS
#include <signal.h>
int raise(int sig);
DESCRIPTION
The raise() function sends a signal to the calling process or thread. In a single-threaded program it is equivalent to
kill(getpid(), sig);
In a multithreaded program it is equivalent to
pthread_kill(pthread_self(), sig);
If the signal causes a handler to be called, raise() will return only after the signal handler has returned.
RETURN VALUE
raise() returns 0 on success, and nonzero for failure.
CONFORMING TO
C89, C99, POSIX.1-2001.
NOTES
Since version 2.3.3, glibc implements raise() by calling tgkill(2), if the kernel supports that system call. Older glibc versions imple-
mented raise() using kill(2).
SEE ALSO
getpid(2), kill(2), sigaction(2), signal(2), pthread_kill(3), signal(7)
