but, if we don't perform it this way, instead,generally speaking, we must need three nested-loop to accomplish it
Code:
for((i=0; i<3; ++i)); do
for((j=0; j<3; ++j)); do
for((k=0; k<3; ++k)); do
echo -n "${i}${j}${k} "
(( k == 2 )) && echo
done
done
done
My purpose is just to show that there are always better solutions to perform the tasks if only you can use your imagination as much as possible!
The post here is intended to show some core concepts and skills that we can perform in shell scripting!

Hi all,
I have been working with java for awhile and because of my school projects I needed to switch C++. I tried to implement some patterns in C++ but unfortunately I couldn't. Specifically, I tried to implement abstract factory pattern but since I used separated files (habitual behavior from... (4 Replies)
I want to create an abstract factory template which will allow me to pass in an "ID" for a subclass and return the singleton instance of that class stored in the factory. It'd be easy to adapt for "multi-ton", but for its present use this isn't necessary.
The requirements are:

Can anyone tell me if this is correct when creating classes in Java?

libcurl(3) libcurl easy interface libcurl(3)NAME
libcurl-easy - easy interface overview
DESCRIPTION
When using libcurl's "easy" interface you init your session and get a handle (often referred to as an "easy handle"), which you use as
input to the easy interface functions you use. Use curl_easy_init(3) to get the handle.
You continue by setting all the options you want in the upcoming transfer, the most important among them is the URL itself (you can't
transfer anything without a specified URL as you may have figured out yourself). You might want to set some callbacks as well that will be
called from the library when data is available etc. curl_easy_setopt(3) is used for all this.
When all is setup, you tell libcurl to perform the transfer using curl_easy_perform(3). It will then do the entire operation and won't
return until it is done (successfully or not).
After the transfer has been made, you can set new options and make another transfer, or if you're done, cleanup the session by calling
curl_easy_cleanup(3). If you want persistent connections, you don't cleanup immediately, but instead run ahead and perform other transfers
using the same easy handle.
