Add to your Perl script
the ability to kill a user’s processes. The requirements for this task include
the following:
·
Add this option to the
menu.
·
Add the code/process
into a subroutine.
·
Use an array to store
the list of processes that need to be reviewed and killed.
·
Process the kill using
the array.
Next, you have been
asked by different users to explain how to compile a program in a UNIX
environment.
Finally, take the
following C program (save it as “power2.c”), and create it as a file
in your UNIX environment:
/* power2.c — Print
out powers of 2: 1, 2, 4, 8, .. up to 2^N */
#include
<stdio.h> <stdio.h>
#define N 16
int main(void) {
int n; /* The current
exponent */
int val = 1; /* The
current power of 2 */
printf(“/t n /t
2^n/n”);
printf(“/t================/n”);
for (n=0; n<=N;
n++) {
printf(“/t%3d /t
%6d/n”, n, val);
val = 2*val;
}
return 0;
}
/* It prints out :
n 2^n

Describe the behavior
when you compile the program, with no options. What is the command
that you would use to compile the code and create the executable
“power2”?
Finally, compare and
contrast the usage of a compiled and interpreted program.
