What happens to active child processes when you fork a parent, do all active processes create another process ? Fork();

Question

Bellow is the code of what is going on , and here is an image of what am i trying to do , any help would be appreciated.Trying to draw the diagram of all the processes Code:

for(i=0;i<2;i++){
  int pid = fork();
    if(pid == 0){
        fork();
    printf("\tA\n");
    }
    else{
        printf("\tB\n");
    }
}//for
printf("\tC\n");
return 0;

}

This is the code of the program

This is the output of the program

Are you sure that the image _of what am i trying to do_ is a _screen shot_? — Armali, Apr 04 '21 at 17:27

Mainly missing from your diagram is in the block Child1 as well as Child1.1 a second run through the for loop, since these children are still inside the loop and their i is initially also 0.
On the other hand, the C=3 in Parent is wrong because C is only printed once at the end, not in the loop.
