#include <stdlib.h>
#include <signal.h>
#include <unistd.h>

This is process 2: He wants to finish the fight with his neighbour once and for all, thus gives the user the choice of action.
#include <stdio.h>
#include <stdlib.h>
#include <signal.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/ipc.h>
#include <sys/shm.h>
/*the tree is made to demonstrate some time lapse after the user inputs the action.
After the user input the process will TAKE SOMETIME to send the signal through shared memory route*/
