Question

The number of 3's in the output of the program main() { printf("1"); fork(); printf("2"); fork(); fork(); printf("3"); }

Accepted Answer

Correct answer: B — The program starts with one process printing '1'. Each fork doubles the processes: 2 after first, 4 after second, and 8 after third. All eight processes execute the final printf("3"), resulting in '3' appearing exactly 8 times.
