    Need a looong int

    Hallo,

    I tried searching, but couldn't find anything. I assume im not the first one asking this, but anyways.

    I need to do some testing with a big integer. Is it possible to have an integer which is somewhere between 20 and 30 digit long?

    Thanks in advance

    Not in standard C. Gnu Math Library or some such can probably provide what you want.

    The usual answer is http://gmplib.org/ or something like it.
    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.
