Question 63 The following program is run. Assume that it's process ID is 1000 and that the next processes created will have process IDs 1001, 1002, 1003, etc. #include #include #include int main() { int i = 3; int child; int status; if((child = fork() == 0) { i= i + 2; printf("X %d %d ", child, i); if((child = fork())==0){ printf("Z %d %d ", child, ++i); return -2; } wait(&status); printf("A%d %d ", child, i); return -1; } wait(&status); printf("Y %d %d ", child, i); return 0; } Assume the output of this program has four lines as shown below. Line 1: XO? Line 2: Z? 6 Line 3: A? 5 Line 4: Y 1001
