Re: [Dev-C++] limit size on arrays

[Jonathan W. <jon...@gm...>]

Hi,

Statically allocated arrays (as in   type var[SIZE];) are allocated on the
stack, so the limit would be the stack size. However, allocating more than a
rather limited number (say 10,20) is generally a bad idea, since you don't
know how big the stack is, etc.

For larger arrays, it's a better idea to dynamically allocate (malloc/calloc
in C) > type *var = calloc(sizeof(type),SIZE); //add checks
You should then be limited by the memory available.
After that, you probably can't allocate more than 2^32-1
bytes, which is the max value of an INT32, supposing you're on a 32-bit system.
That
said, it's unlikely you'll be able to allocate that much anyways: that's 4Gb....

HTH,
Jonathan
