D - Unicode: Japanese Study Program

I'd like to write a program that randomly cycles through a bunch of Japanese

fill-in-the-blanks and multiple choices. It should be implemented with a
graphical user interface as I will be using this to help my son (5) with his
Japanese studies.

I'm not looking for someone to do this for me (I would me out of my mind to
along those lines), however I cannot provide an example of what I've done
because I do not know where to begin. Any suggestions would be greatly
appreciated.

I though this would be a great way to start learning how to actually
program, and help my son along the way. If someone could point me in the
right direction, I'll try to find my way from there. Thanks a million.

Compiler message:
e1.d(8): function expected before (), not 'char[6]'

That's where Pascal's set would kick in!

"whitespace" is a string, containing all characters which are considered
to be whitespace. To check whether some certain character is a
whitespace, you can use "find" from string module. Description:

---8<---
int find(char[] s, char c)

Find first occurrance of c in string s. Return index in s where it is
found. Return -1 if not found.
--->8---

so that you do:

if (find(whitespace, i) == -1){
   // code here only executes if i is not whitespace character code
}

An alternative were to use a bit-array, which would be much like Pascal 
set. An advantage of a set, is that it's always a bit array of a minimun 
size of stack slots, which also returns "false" for all entries outside 
its range. To limit the overuse of sets, they only allow up to 256 
entries though, that is you can't match the whole unicode table with a 
set. Imagine how huge this set would become! Definately too large to be 
passed on the stack :)

In general, you might consider using Delphi or Java for such a task, 
because there are no beginner's ways to D yet... You have to know C (or 
rather a common subset of C and C++, which is popular and sufficent) 
well to get along with D. Besides, there are good beginers' books to 
Java and Delphi and tons of libraries. You won't be able to freely and 
simply use C libraries in D for a while, forget about C++ ones. Delphi 
is my favorite, although i miss a lot of features in it which i find in 
D. But D is not as clean and lacks of some Pascalese as well.

however if you've not programmed b4, I would start with something a little

currently there are no complete ports of the win32 API

I don't think the winmm lib bits are ported yet, the headers are in
/dm/include awaiting the port :)
the rest is going to be up to you.

saves you having to worry what your doing.

(those should just be in gdi32.lib, so `dmd winsamp gdi32.lib` works [just
tested it])

For Windows, Linux and IRIX, there is Audiere (http://audiere.sf.net),
LGPL licensed and very nice. There is of course a potential issue in
that the latest versions are 100% C++, I'm not sure how well that'd
work with D. (My guess is not at all.) But if you can get it to work, it
supports MP3, Ogg Vorbis, Ogg Flac, MOD, S3M, IT, XM, wav and probably
some others.

Most libraries are written with C linkage, so that they can be used from 
C and from C++.
I looked at it a bit and i've got a bad feeling. It doesn't seem to be 
accessable from C. Another issue is a number of functions for which you 
need to fix prototypes - in FMOD you only need three or so, i guess 
that's somewhere about the bottom. Of course, anything can be hacked. 
But it would be much.
However, the links page of the project is very interesting. Some shall 
be very useful to me later. Thanks.

http://tuo.planet-d.net/skysound/
may be intereisting for Andrew's purposes.

But i can't promise soon help with anything except for FMOD.

Of course, that's why D is designed to be able to directly access such
libraries!
