problem with big programs

[Mohsen]

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.

Hello everybody,

Every time that I change the size of my arrays (pointers)

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.
