    Well without seeing your code, it's hard to say which of the many 1000's of ways you could have messed up applies to you.

    Second, newbies shouldn't be anywhere near threads until you've had 6 months of solid programming experience writing normal single-threaded programs.
    Further, nobody should be writing thread programs unless they've done a thorough analysis and design to make sure threads are the best solution to the problem, and that they have a good design that will work. Just throwing threads at a problem is a recipe for disaster.

    Writing threads is hard; debugging them is harder still.

    When (not if) you wind up with any of the following situations, it will truly mess with your mind.
    Race condition - Wikipedia
    Heisenbug - Wikipedia
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
