I am just learning D, and playing around. So I have no good reason why one
would do the following, but I also don't understand why it doesn't work...
I was trying to make an associative array with int[5] as the value type. That
didn't work properly. int[] did, and I don't understand why.
Here is
Sorry, this could be a bug report and not a question, and probably the wrong
place to post it then.
I installed gdc according to the instructions given in
http://www.dsource.org/projects/tango/wiki/MacOSXInstall
from

That was the problem:
dmd.conf was copied to /usr/local/bin
The copy in /etc did nothing. The copy in /usr/local/bin was overriding any
DFLAGS I set.

D is really great. I am trying to implement a medium sized project to get to
know it.
For this I need a sorted data structure, with cheap search, and somewhat cheap
forward and backward traversing.
I thought I should use tango (though it is a bit confusing that there is so
much overlap between

Good! I just managed to compile my first program using 0
The fact that D has real typedef, not like the fake ones of C++ is, I think,
one of its great features.
But the fact that there is no automatic cast, together with typedef is causing
me problems.
The one I'm currently fighting with is initialization:
typedef long location ;
location a[] = [1,
Another question about typedef...
I am using
typedef long location ;
Now I would like to use tango.math.random.Random. But I am having problems with
calling r.uniformR( hi ) when r is a random genarator, and hi is of type
location.
I need to call
r.uniform!(long)( cast(long)(hi) ) ;
This is u
typedef long location ;
location a[] = cast(location[])[1,2,3,4] ;
Seems to work.
I was afraid of the mess that would happen if I cast (int *) to (long *) in C...
Can I trust it? Is that the "right way" to do it?

[] = a[]
doesn't seem to work...

After a discussion on digitalmars.D I played with arrays a bit. Look at the
following code:
int[] a = [1,2,3,4,5,6,7,8,9] ;
int[] b = a ;
a ~= 10 ;
b ~= 11 ;
b[0] = 12 ;
Stdout(b).newline ;

Yes. My question relates to what happens when you go beyond the bounds
originally assigned.

(We were talking about something like
int a[] = [1,2,3,4,5] ;
b = a ;
a ~= 6 ;
b.length = b.length+1;)
Hmmm... yes, that has some l
15 matches
