Visually what happens to fork() in a For Loop

Question

I have been trying to understand fork() behavior. This time in a for-loop. Observe the following code:

#include 

void main()
{
         


        

Answer 1

1. Yes, it's correct. (see below)
2. No, i++ is executed after the call of fork, because that's the way the for loop works.
3. If all goes successfully, yes. However, remember that fork may fail.

A little explanation on the second one:

for (i = 0;i < 3; i++)
{
   fork();
}

is similar to:

i = 0;
while (i < 3)
{
    fork();
    i++;
}

So i in the forked processes(both parent and child) is the value before increment. However, the increment is executed immediately after fork(), so in my opinion, the diagram could be treat as correct.
