What will these programs print? (If there are multiple possible output sequences, choose one valid sequence and display it.) Are there multiple possible output sequences for this program (In other words, could the same output statements print in a different order each time you run the program) If so, explain why, If not, explain why your answer to the previous question is the only possible output. Process management questions (definitions for programs prl and pr2) prl: pr2: int main(int arge, char **argv) { int main(int arge, char **arg) { pid_t pidi, pid2; pid_t pid; pidi - fork(); printf ("P2 ts ", argv[1]); pid - fork(); if (pidi 0) if (pid 0) print ("P1 child "); wait (NULL); execlp("./pr2", "pr2", printf ("P2 parent *s ", "fork 1", NULL); argv[1]); else { else if (pid = 0) printf("P1 original "); printf ("P2 child #s ", wait (NULL); argv[1]); return 0; pid2 - fork(); ) if (pid2 - 0) printf("Child of P1 "); I execlp ("./pr2", "pr2", "fork 2", NULL); ) else { printf ("Still P1 original "); wait (NULL); } return 0; Note: prl always runs first and is invoked with the command line: . /pr1
