  • Can this statement ever evaluate to FALSE?

    - by BojanG
    I stumbled upon this while doing a review and the author is not available: int n = Convert.ToInt32(text); if (((n > 0) || (n < 0)) || (n == 0)) { return 1; } The code in general looks solid and it's hard for me to believe that the only purpose of this snippet is to confuse reviewers, but I don't see a way for this condition to fail. Am I missing something?

  • Using two threads and controlling one from the other in java?

    - by sidra
    Can someone please help me out. I need to use two threads in a way that one thread will run permanently while(true) and will keep track of a positioning pointer (some random value coming in form a method). This thread has a logic, if the value equals something, it should start the new thread. And if the value does not equal it should stop the other thread. Can someone give me some code snippet (block level) about how to realize this?

  • Integer to Character conversion in C

    - by nthrgeek
    Lets us consider this snippet: int s; scanf("%c",&s); Here I have used int, and not char, for variable s, now for using s for character conversion safely I have to make it char again because when scanf reads a character it only overwrites one byte of the variable it is assigning it to, and not all four that int has. For conversion I could use s = (char)s; as the next line, but is it possible to implement the same by subtracting something from s ?
