Is there a max array length limit in C++?

Question

Is there a max length for an array in C++?

Is it a C++ limit or does it depend on my machine? Is it tweakable? Does it depend on the type the array is made of?

Answer 1

If you have to deal with data that large you'll need to split it up into manageable chunks. It won't all fit into memory on any small computer. You can probably load a portion of the data from disk (whatever reasonably fits), perform your calculations and changes to it, store it to disk, then repeat until complete.
