Justify your answer. a) Boot time b) When the printer generates Out of paper error c) When the operating system gains control Consider a process (id= 2256) creates a child process (id = 2257) and child process further creates a child process (id= 2258). What will be output at statement (1), (2) and (3) along with the process generating this output, for the code given below: int main() { int id1= fork(); cout
