arrays

i'm writing a program that stores words in a two dimensional array. my program works fine if i use this array[4000][30], however i want to store a lot of words in this array and if i try and make it bigger......say array[10000][30] then it doesnt work right. any idea of why this might be?

Why do you need such a large array anyways? array[10000][30] would take up 300KB of memory.

because i'm downloading words from web sights and if its a fairly large websight then it will have a lot of words on it.

Why don't you just write the words to a file? What are you planning on doing with the words after you retrieve them? We need more info.

try it off the heap.

what do you mean off the heap

Using the heap instead shouldn't make a difference, you'll have the same problem. Use virtual memory.

he means you are declaring your array on the stack. A large array like that causes a stack overflow- not a good thing- and so you should use some sort of dynamic memory allocation.
You will need to use new/delete or new[]/delete[] or malloc()/free().
Making dynamic 2d arrays has been done many times so if you search the c++ boards you will come up with an example.
