2d array error c++

[MisterWhite]

so i determined that the declaration of my 2D array is the problem (commented everything out, left only the variables and the commented out the 2d array, and all was good), any ideas why the mistake?

string mode[1000], mode1 [1000], mode2[1000];int startX[1000],startY[1000], endX[1000],endY[1000];int beatNeighbour[1000][1000];

Console window: http://imgur.com/yKP8nFk

EDIT: with that "return" i cannot output anything to console, even a simple cout<<"a";

EDIT 2: how to allocate memory for my 2d array? (when declaring int beatNeighbour [1000] [100], no error)

there's a space in your mode1 [1000] declaration?

[MisterWhite]

there's a space in your mode1 [1000] declaration?

it could be mode1           [1000]             ;

white space is not an issue

int beatNeighbour[1000][1000];

this makes the error

[Marvzl1357]

it could be mode1           [1000]             ;

white space is not an issue

int beatNeighbour[1000][1000];

this makes the error

indeed it doesn't, I've never declared an array with whitespace between the name and dimension because I thought it matters

In which case, sorry i have no idea why it doesn't work, I couldn't see anything wrong with those declarations

Maybe it's just that you're allocating too much on the stack, which isn't all that big.

I don't know the stack size, it depends on the OS and compiler(-options), but one million ints is several MB, which is more than usual.

You could try to use dynamic variables, as the heap is a lot bigger than the stack.

Edit: Google said that the default stack size on Visual Studio is 1 MB, so if that's what you're using, that's the problem. But I'm pretty sure you can configure the stack size. I know on Linux that stack size is a variable you can set in bash and not a compiler option. I'm not sure about Windows.

i thought that that might be an issue, but i dont know how to do that

after doing the third option:

int **beatNeighbour= new int *[1000];    for(size_t i=0; i<1000; i++)        beatNeighbour[i]=new int [1000];    for(size_t i=1000; i>0; i)    {        delete[] beatNeighbour[i];    }    delete[] beatNeighbour;

 I get this error:

cannot convert 'int**' to 'int (*)[1000]' for argument '7' to 'void duomenys(std::string*, std::string*, int*, int*, int*, int*, int (*)[1000], int&)

in my fucntion:

void duomenys(string mode1[], string mode2[], int startX[], int startY[], int endX[], int endY[],int beatNeighbour[][1000], int &counter);

(error in main):

    duomenys(mode1, mode2,startX,startY,endX,endY,beatNeighbour,counter);// error here

in my fucntion:

void duomenys(string mode1[], string mode2[], int startX[], int startY[], int endX[], int endY[],int beatNeighbour[][1000], int &counter);

what happens if you change 'int beatNeighbour[][1000]' to 'int **beatNeighbour'

cannot open output file C:\...\main.exe Permission denied.

 

BTW, do i use my 2D array as normal array?

 

EDIT: googled, had to end the process with task manager. when lanched it displays black console window without ANY text
