    Why do you need to create an array of that size?

    Well you can try: Using static, or allocating the memory dynamically using malloc

    For heavens sake get a better compiler!!!
    64K is the max size of any single object with that stone age fossil

    sizeof(long int) == 4 (probably)
    17000 * 4 > 64K (oops, you lose!)

    Please don't tell me your OS is XP, because that's just like buying a nice new ferrari, and replacing the engine with a 200 year old steam engine.
    Talk about crippleware!

    And I bet you agonised over whether your machine was up to spec for sound and graphics.
    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.

    Salem is right, and i've tested, gcc compiles ar[17000] fine.

    i really want to know why people are still using old compilers on new systems? (assuming he is using a new system, but if he isnt then he should know old systems cant use more than 64k?)
