I have the following C code, how can I do the same in D.

Info **info;
info = new Info*[hl + 2];

int r;
for(r = 0; r < hl; r++)
{
        info[r] = new Info[vl + 2];
}
info[r] = NULL;

I suggest you to ignore ketmar, he's not helping :-)

Is your code initializing info[r+1]?

This is roughly a D translation (untested):


void main() @safe {
    import std.stdio;

    enum uint hl = 5;
    enum uint vl = 7;
    static struct Info {}

    auto info = new Info[][](hl + 2);

    foreach (ref r; info[0 .. hl])
        r = new Info[vl + 2];

    writefln("[\n%(%s,\n%)\n]", info);
}


Output:

[

[Info(), Info(), Info(), Info(), Info(), Info(), Info(), Info(), Info()], [Info(), Info(), Info(), Info(), Info(), Info(), Info(), Info(), Info()], [Info(), Info(), Info(), Info(), Info(), Info(), Info(), Info(), Info()], [Info(), Info(), Info(), Info(), Info(), Info(), Info(), Info(), Info()], [Info(), Info(), Info(), Info(), Info(), Info(), Info(), Info(), Info()],

Is this what you look for?
