if(fork()==0)

    n=n+700;

    printf(“%d, “,n);

}

Which of the following output is not possible?

1. 2,4,1,701,704
2. 1,2,4,704,701
3. 2,704,4,701,1
4. 1,704,2,4,701

Comments

Option d, as program will print 2 before 704 which is contradicted by option d.

Answer 1

 

As all five values are possible .

Due to context switch every option is Possible.

So i think none is wrong.

I think all combinations should be possible so none is wrong.
