I often use sample programs on the Internet to study new programming languages.

The other day, I was browsing a textbook in that programming language at a bookstore, and I noticed that almost all programs posted on the net are

"exactly the same"

-----

I am referring to that program, so I don't have any intention to criticize them.

However, at least I wanted to make the application a different one, or something "ingenuity".

The reason is that the "ingenuity" has the effect of inducing another "ingenuity".

Anyway,

I was wondering why the sample program posted on the net was just a "chat room" application. However, I finally understood the reason.
