Program 1: Using either a UNIX or a Linux system, write a C program that forks a child process that ultimately becomes a zombie process. This zombie process must remain in the system for at least 10 seconds.

Program 2: Using either a UNIX or a Linux system write another C program that uses the FIRST program. That is, you do not have to enter the commands ps and kill manually. But your program has to: (a) create zombie processes by running your C program of #1, (b) Obtain the state of each process and find if there is any process that is zombie, (c) Show a list of processes with their states, (d) kill the parent of any process that is zombie, and (e) show the updated list of processes with their states.
