Consider the following code fragment:

 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?

u = x + 10 and v = y

u = x + 10 and v != y

u + 10 = x and v = y

u + 10 = x and v != y

This question is part of this quiz :
