func new

[Dabroz]

can i allocate memory in multidimensional arrays by new?

for example:

int* something;
something=new int[20][20][20];

it doesn't work! how i can make that?

Yes.


for example:

int* something;
something=new int[20][20][20];

It does not compile because the type of the 'new' expression is
not


int*


but


int (*)[20][20]


Declare your pointer as


int (*something)[20][20];


and it will compile.

But better, if you absolutely must program at the lowest
level instead of using the standard library, 'typedef' like so:


int main()
{
struct Tensor
{
int elem[20][20][20];
};

Tensor* t = new Tensor;

t->elem[1][2][3] = 666;

delete t;
}


General recommendation is, however, to use standard library and
boost collection classes.
