Stack size

How do I change the size of the stack in c++? I would like to use larger arrays, and the stack overflows when I make them as large as I would like.

Thanks,

Use std::vector?

Thanks, that does the trick. Will I notice any difference performance wise?

You shouldn't, vectors shouldn't be much slower then an array, if not the same.

It depends on your OS and compiler.

Besides, as Hunter2 suggested, take it as a hint that you should be looking for a better solution ;)

Thats interesting I though the stack was suposed to grow when all of it's space was used up?

Just out of curiosity, why would you think that?

That depends....

Code:

---

$ ulimit -a
core file size        (blocks, -c) unlimited
data seg size        (kbytes, -d) unlimited
file size            (blocks, -f) unlimited
open files                    (-n) 256
pipe size          (512 bytes, -p) 8
stack size            (kbytes, -s) 2043
cpu time            (seconds, -t) unlimited
max user processes            (-u) 63
virtual memory        (kbytes, -v) 2097152

Just a little under 2MB here.
Of course I could set "unlimited", but it would still be limited by the very real limits of physical memory / swap space / address space.

How you manipulate the same thing in say windows is another matter.

You can't just put char x[1000000] inside a recursive function and sit back hoping that it'll work.
