    rand() doesn't randomize

    In a little mini game i have made i use some rand() % blabla to check if you hit an enemy or not and for some other things aswell. But each time i run the program the same things happen in the same order.
    Why?

    Well first of all you posted while i was writing the thank you reply so i didnt know that you had replied.
    Second you didn't provide such a good explanation.
    What happens if i put randomize() before the main()?
