Assume that the following program is compiled to an executable file called getAnswer and that it is called as follows: ./getAnswer 4 #include #include #include #include #include #include int main (int arge, char 'argv[]) { int pid: int err: int in: int status: char buf[10] i = atoi (argv[1]); pid = fork(); if (pid == 0) { if (i == 1) exit (1) 1 sprintf (buf. "%d", 1/2): err = execl ("/getAnswer", "getAnswer" buf. "8". NULL); if (err ** - 1) exit (2): else err waitpidl-1 &status. O); WEXITSTATUS (status) + i; if (argc = 3) exit (n): else I= 1 exit (1); 3 sprintf (buf, "%d", 1/2); err = execl ("/getAnswer", "getAnswer", buf, "8". NULL); if (err == -1) exit (2); 3 else { err = waitpid(-1, &status, 0); n = WEXITSTATUS (status) +i: if (argc 3) exit (n); else printf ("Result = %d ", n): 3 } Predict the output by selecting from the following alternatives: Result = 1 Result = 5 none of these Result = 2 Result = 4 Result = 8 Result = 1 Result 3
