Hello, 

import std.stdio; 

int main() { 

static char[5][2] string = ["house","car"]; 
writefln("string[0] = %s",string[0]); 
writefln("string[1] = %s",string[1]); 

return 0; 
} 

Why is the static keyword for "char[5][2] string =["house","car"];" 
necessary?

I have the same question.  Also, why can't I initialize a non-static array with
values at declare time? ie.

char[][] string = ["house","car"]; 
..
more code
..
string.length = string.length + 1;
string[string.length - 1] = "dog";

thanks.

 I have the same question.  Also, why can't I initialize a non-static
 array with values at declare time? ie.


Since D does not yet support dynamic population of arrays...
It's a missing feature, possibly even not until D 2.0 ! :-(

Meanwhile, you need to fill out the arrays at run-time instead...
(BTW; this extra step is needed with Java arrays and hashes too)

char[][] strings;
strings.length = 2;
strings[0] = "house";
strings[1] = "car";

You can do it in a "static this() { }" block, to make it automatic
to populate e.g. global variables or calculated "constant" fields.


 more code
 ..
 string.length = string.length + 1;
 string[string.length - 1] = "dog";

You can use this instead, if you like: (less typing, and easier too)

strings ~= "dog";

PS. I changed "string" into "strings", plural because of the array?
