I read about Associative Arrays (which remind me of hashes from Ruby/Perl), and wanted to do a test... and failed.

I'm using this:
char[char[]] [] my_aa;

To try to make an associative array that I can use like this: my_aa["hello"] = "Hello, world!";

However, when I compile, I get this:
cannot implicitly convert char[5] to int

How can I declare the variable the correct way?
I guess that I need to make an associative array of strings.

Very close. Try this instead...

  char[][char[]] my_aa;


The format is ...
  <datatype>[char[]] <idname>;

and in your case the <datatype> is 'char[]'.

What you had declared was a dynamic array of associative arrays of char.

Oh! OK, that makes sense now! They should add that
to the documentation on arrays.

Quick follow up, can you use associative arrays like this:
char[] key = "test";
char[][char[]] my_aa;

my_aa[key] = "Hello";

printf("MSG: %.*s\n", my_aa["test"]);

This works for me...

 char[][char[]] my_aa;
 char[] key = "hello";
 void main()
 {
   my_aa[key] = "Hello, world!";
   printf("%.*s", my_aa[key]);
 }
