Fork(System call) - Number of process

I'm new to system calls. Here is my question. If segment_A creates 'n' processes. How many number of processes in total are created by the following code.

fork();
segment_A

My guess is '2n+2' processes including the child and parent processes. Please shed some light on this. Its really confusing to understand fork system call.

Thanks in advance.

fork creates another process so after fork system call there will be two process and each of the process will create "n" new processes. So there will be 2(n+1) = 2n + 2 processes and 2n + 1 processes will be created by the code segment.

The parent process has already been created. fork() creates a single additional process, and each process then creates n processes.
