A process executes the code fork(); fork(); fork(); The total number of child processes created is

1. 3
2. 4
3. 7
4. 8

Correct answer: 7

Solution

Each call to fork() creates a new process, and the number of processes doubles with each fork. After three fork calls, the total number of processes is 2³ - 1 (the original process is not counted as a child), resulting in 7 child processes.
