Can any help me to write program using Fork in C to generate this tree structure?

[shatha94]

the tree in the the attachment below

this is my code that I'm tried to write :

#include<sys/types.h>
#include<stdio.h>
#include<stdlib.h>
#include<unistd.h>

int main()
{

printf("the parent id %d" , getpid());

pid_t pid1,pid2,pid3;

for (j=0;j<3;j++)
{
pid1=fork();
printf("%d",getpid());
}
if (pid1==0)
{
 pid2=fork();
elseif (pid3=fork();
}
 if((pid2 == 0)&&(pid3 == 0)) 
   {
       if (pid1 !=0)
       fork();
   }

printf("the process id %d" , getpid());

return 0;

}
