Consider the following code fragment:
if (fork() == 0)
{ a = a + 5; printf("%d,%dn", a, &a); }
else { a = a –5; printf("%d, %dn", a, &a); }
if (fork() == 0)
{ a = a + 5; printf("%d,%dn", a, &a); }
else { a = a –5; printf("%d, %dn", 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?
- a)u = x + 10 and v = y
- b)u = x + 10 and v != y
- c)u + 10 = x and v = y
- d)u + 10 = x and v != y
Correct answer is option 'C'. Can you explain this answer?

Consider the following code fragment:if (fork() == 0){ a = a + 5; prin...
fork() returns 0 in child process and process ID of child process in parent process. In Child (x), a = a + 5 In Parent (u), a = a – 5; Therefore x = u + 10. The physical addresses of ‘a’ in parent and child must be different. But our program accesses virtual addresses (assuming we are running on an OS that uses virtual memory). The child process gets an exact copy of parent process and virtual address of ‘a’ doesn’t change in child process. Therefore, we get same addresses in both parent and child. See this run for example.

"a = %d\n", a);}
In this code fragment, the fork() function is used to create a new process. The fork() function returns a value to the parent process and the child process. In this case, if the fork() function returns 0, it means that the code is being executed in the child process.
Inside the if statement, the variable "a" is being modified by adding 5 to its current value. Then, the printf() function is used to print the value of "a".
If the fork() function returns a non-zero value, it means that the code is being executed in the parent process. Therefore, the code inside the if statement will not be executed by the parent process.
Overall, this code fragment creates a child process and modifies the value of "a" in the child process. The value of "a" in the parent process remains unchanged.
