For example:

I am very new to D Language and I apologize for my bad question.

Hi,
i have seen that a simple operation (in a loop) is faster than
the equivalent UDF.
The first example takes 4 seconds, the second example takes 16
seconds.
Local variables influence the speed of execution?
Thank you very much.

I have read much, before to write here.
How can i store, to an int variable, the milliseconds of the

It's simple, but i don't find the solution.

Hi.
How can I know the amount of RAM allocated by a vector?
For example:
string[8][1000] array;
for(int i=0;i<1000;i++) {
array[i]=["","","","","","","",""];
}
how can I know the amount of bytes of above matrix?
Can I clean the memory ofter his use, without
28 matches
