In addition to what Neia said, you shouldn't use pointers to dynamic
arrays. Such things are really hard to allocate on the heap, since new
int[] just makes an array, not a pointer

You're taking the address of a local variable and persisting it
beyond the variable's scope. This is not safe in general;

Actually it's not, let's not confuse people with the terminology here.
To recap for people new to arrays: an array in D is really just a
struct, e.g.:
struct Array
{
int* data;
size_t length;
}
Array myArray

Here's a handy introduction:
http://nomad.so/2013/07/templates-in-d-explained/
Nodes are reference types in D, so probably you don't need to
use a * for Node. Alternatively use a struct handled by pointer.
"auto content;" can't compile, you need a type, or you have to
template Node on T and use it for content.
Bye,

Youre right, it compiles now, and the obje
Arjan Fetahu:
Since each Node connects to multiple others i came up with this
solution.
class Node {
auto content;
Node*[] nodes;
//..constructor..
}
Nodes are reference types in D, so probably you don't need to use
a * for Node. Alternatively use a struct handled by pointer.
Keep in mind that, unlike in c++, D classes are reference
types:
class Node
{
Node[] nodes; // This is valid
}
Structs are value types though, so using a struct in the above
example is illegal.
You mean:
struct Node {
Node[] nodes;
}
or
struct Node {
Node*[] nod

That's not true. Indeed
in D (I have a little
experience in c).
I wanted to create an array of pointers for creating a node
with multiple
connections. In C you can make one directly (node
*nedePtr[]). What is the equivalent for the D's syntax??

Arjan
node*[] nedePtr;
Ok. Thank You!
