Hi,
I have a design question and I'd like to hear some advice. Let's
say that I want to create a method to sort an array:
arr.sort(asc);
I think usually this would usually return a new set of that array
but now sorted.
But If I want to do this in the original, I think I would do this:
Hi H. S. Teoh,
I think you misunderstood my question, since English is not my
first language maybe this was a problem from my part, but anyway,
I'm not talking about "sort" from main library.
This example was if I had designed my "own version".

Hi,
Could anyone please tell me why the properties of min/max of a
char returns a "char type" and not a value as an int?
I just got this while playing around:
void main(){
import std.stdio;
writeln(char.max); // "nothing"
writeln(typeid(char.max)); // "char"

If the size of MyClass is 9 bytes why do MyClassO1 & O2

Because those addresses(4FFB20 4FFB24) are the addresses of
