How to solve zombie and orphan process problems ?
Please explain with an example...

when you fork a new process, it's parents responsibility to query the exit status of the child. This exit status can be queried by system calls like 'wait','waitpid ' etc

Code:

#include <stdio.h>
#include <stdlib.h>
#include <sys/wait.h>
main()
{
  int i, j, status;
  i = fork();
  if (i > 0) //parent 
  {
    j = wait(&status);
  } 
  else //child
  {
       sleep(1000);
        exit(0);
  }
}

In this code parent will wait till child finishes.
So in short..parent must issue a wait call to avoid a zombie processes.
