Create a fan of processes and chain of processes. Ask the user for the number of processes to be created.

CODE: (i) CHAIN PROCESS

#include <stdio.h>

#include<unistd.h>

void main()

{

  pid_t cid=0;

int n,i,a=5,j;

printf("enter numbers of Processes");

scanf("%d",&n);

for(i=0;i<n;i++)

{

 cid=fork();

 if(cid!=0)

 {

   printf("%d Process id:%d Child:%d\n",i,getpid(),cid);

   break;

 }

}

}

OUTPUT:

(ii) FAN PROCESS

#include <stdio.h>

#include<unistd.h>

void main()

{

  pid_t cid=0;

int n,i,a=5,j;

printf("enter numbers of Processes");

scanf("%d",&n);

for(i=0;i<n;i++)

{

 cid=fork();

 if(cid!=0)

 {

   printf("%d Process id:%d Child:%d\n",i,getpid(),cid);

 }

 else

    break;

}

}

OUTPUT:
