1. (Handwritten) What is the output of the following processes? Can the output of the program change every time we run it? Explain briefly. int x; int main() { //global int rc; x = 0; rc = fork(); ===== if (rc == 0) { } else { x = 1; printf ("child: %d ", x); printf ("parent: %d ", x); x = 2; } printf("end: %d ", x);
