    problem with big programs

    Hello everybody,

    I have written a program and I have included 5 other programs (which I
    have borrowed 3 of them) in my program. Every time that I change the
    size of my arrays (pointers) I get different answers and sometimes no
    answer. I think I have a memory problem and I have tried to solve it
    many times but I couldn't. Does anybody have any idea how to solve
    such a kind of problem?
    I have also tested the program in UNIX and the results are different
    from Windows!
    I feel the program is so big and I cannot manage how take care of all
    of it.


    Thanks,
    Mohsen

      Perhaps your deconstructors are deleting information which you might
      need, or maybe you didn't program your copy constructor correctly. Try
      taking the deconstructors out temporarily and see if that fixes it, if
      it does you know where your problem is. Also, try stepping through your
      program and see exactly where it is going wrong.

          Could you go into more detail about what the "(pointers) " bit means?

          Have you tried something like http://valgrind.org/ ?

              Are we supposed to just guess? We have absolutely no idea what your code
              looks like, or what the problems you're seeing are. Please read the FAQ on
              how to post to this newsgroup:

              (By the way, a common method of debugging a program is to use a debugger.
              Try it.)

                  I am simulating a population with different number of individuals, each
                  individual has some genetic information. Those information are in
                  pointers.
                  I have not used like http://valgrind.org/ yet.
