Question

in other question I asked how to compile a vector with huge amount of data because I wanted a vector with a dictionary of 107776 entries, and I couldn’t compile it.

I solved it thanks to this answer‘s code:

char const * const dict[] = {"aaron",...};

But now the problem is that when I attempt to access one entry…

cout<<dict[431104]<<endl;

…the program freezes and Windows wants to close it.

Why does it happen? How can I solve it?

Edit: sorry, it was my fault. As tbroberg and Seth Carnegie noticed in this answer, the mistake was that I thought that sizeof(dict) was the length of the array (instead of sizeof(dict)/sizeof(*dict)).
Therefore, 431104 was far out of the bounds of the array (its length is 107776).

Answer 1

You are allocating 107776 char*s on the stack, which might be enough to cause a stack overflow on your computer. You can try allocating the char*s on the heap and use an initialiser list:

const char** dict = new const char*[107776] {"aaron",...};

// ... use dict

delete[] dict;

That should fix the problem (if the problem is stack size, which I think it is).

Also, I just noticed that your index, 431104, is far out of the bounds of the array, which is of the size 107776 (I misread it as 1 million before). Are you sure your problems haven’t just been out-of-bounds indices?
