I have the following code.
Heavily cutdown.

How would I do the same thing in D?

//////////////////////////////
class NInfo
{
public:
	Stack<int> info;
}

int cols = 5;
int rows = 10;
	
ninfo = new NInfo*[cols+2];
int r;

for (r=0; r<cols+1; r++)
{
	ninfo[r]=new NInfo[rows+2];
	for (int c=0; c<rows+1; c++)
	{
		ninfo[r][c].info.push(r);
		ninfo[r][c].info.push(c);
	}
}

Do you want something like this? struct NInfo { public int[] info; } void main() { int cols = 3; int rows = 5; auto nInfo = new NInfo[][](rows + 2, cols + 2); foreach (r, row; nInfo) foreach (c, ref item; row) item.info ~= [r, c]; // not so efficient import std.stdio; writefln("[%([%(%s, %)],\n %)]]", nInfo); } Output: [[NInfo([0, 0]), NInfo([0, 1]), NInfo([0, 2]), NInfo([0, 3]), NInfo([0, 4])], [NInfo([1, 0]), NInfo([1, 1]), NInfo([1, 2]), NInfo([1, 3]), NInfo([1, 4])], [NInfo([2, 0]), NInfo([2, 1]), NInfo([2, 2]), NInfo([2, 3]), NInfo([2, 4])], [NInfo([3, 0]), NInfo([3, 1]), NInfo([3, 2]), NInfo([3, 3]), NInfo([3, 4])], [NInfo([4, 0]), NInfo([4, 1]), NInfo([4, 2]), NInfo([4, 3]), NInfo([4, 4])], [NInfo([5, 0]), NInfo([5, 1]), NInfo([5, 2]), NInfo([5, 3]), NInfo([5, 4])], [NInfo([6, 0]), NInfo([6, 1]), NInfo([6, 2]), NInfo([6, 3]), NInfo([6, 4])]] Bye, bearophile

In the D Phobos there is no efficient stack yet, so I've used a dynamic array. If you need to append many items use an appender or use some truly segmented stack data structure. Also if NInfo must really be a class, things become a little more complex. Bye, bearophile
