GATE CS 2005 – Question 70

Consider the following code fragment, where the variable a already holds a value before the fragment starts executing:

if (fork() == 0) {
    a = a + 5;
    printf("%d, %d\n", a, &a);
} else {
    a = a - 5;
    printf("%d, %d\n", a, &a);
}

Let \(u, v\) be the values printed by the parent process, and \(x, y\) be the values printed by the child process. Which one of the following is TRUE?
