#Talk about writing out a program.

Talk about writing out my first program.
When I was a junior high school student, the first program I touched was N80-BASIC.
I won't forget the starting cord, I still remember it, the following sentence was completely in my head.

N88-BASIC

WIDTH 80,25.
CONSOLE 0,25,0,1
LOCATE 0,0
PRINT "HELLO WORLD"

Of course, in the old days of computer screens, there was nothing but a useless, inorganic cursor.

Writing out programs is still the same, and computers are truly inorganic.

The most important thing at the beginning of a new programming language or development environment is to say hello to the programmer first.

This is true not only in the programming world, but in the real world as well.

If even a single greeting is conveyed, people will talk to you in some way.
If you just walk up to them without knowing what to do, they will return you a puzzled look or, in the worst case, tell you to go away.

#Past stories, digress a little bit...

I digress a bit when I talk about the past...
The first time I went on a college graduation trip, I was in transit at an American airport.
I forgot to take my ticket out of the caster case.
Then I managed to explain the crisis to a black woman at the airport counter.
I still remember saying, "No ticket! No ride!"
being really turned away.

After that, I went to the airport help desk.
An old man came over and took me to baggage claim.

I had a bag that was almost silver in color.
"Gold," and somehow managed to retrieve the bag.
We were able to get our tickets.

The horror of it, and the laughter from the friends who went with me.
I still remember this episode from my first trip abroad.
(The nostalgic video became a topic of conversation at the reunion and is still posted on youtube)

#The main point of this topics.
I mean, the guy who says programming languages, what do you write in the first place?
This rule has not changed since the beginning of time
If you don't know this, you can't do anything at all.

In the meantime, the chatbot side of the house will be able to
"What should I write, sir?　
Can't you kindly tell me how to start the code?

When AI comes out, at least, we'll be able to solve this engineer shortage in earnest.
The gap in communication with computers.
I am hoping that they will fill it in.

That's why today's topic is the one I've been learning recently
The starting point of the programming language is explained in a way that even beginners can understand
I'm going to try to put it together in my own way.

##python ---> import
　In the case of python, it's an import statement.
　This could not be more wrong.

C# ---> using

　In the case of C#, it is a using clause.
It's not the start of an enka song.

C ---> #include < >

Let me add to that because I remembered it a long time ago.
C++ might be basically the same, though.

node.js ---> require()

Dare I mention JavaScript, which is plunged into HTML?

VB.NET ---> Imports

Unfortunately, there are no such conventions in VBA, so
This is written in the case of VB.
　

JAVA ---> import

　I've never used JAVA personally, so I'll write it out as knowledge.

the others

Typescript
RUBY
PHP
GO

I guess there's a lot of program languages, but I don't know any more.

#Like a greeting
Of course it's necessary, you say "hello" to your neibor naturally.
But also it need to catch a glimpse of other people's conversations,
when you read the cord written by other people, such as GITHUB, etc.

Let's start with the opening remarks.
Because this is where it all begins.
The only way to understand the program is to unravel it from here.

This greeting is very important. The greetings are filled with general knowledge about the manners, culture, and education of the other country.

Especially nowadays we call it namespace, but we don't even need to name it "namespace".
To begin with, it's just a tree structure, the name of a directory, so I'd like you to say that in a way that I can understand it.

Also, PYTHON uses things like ENV, such as virtual space, but even those are just additional folders that are temporarily created as a running environment, and the phrase that IT engineers use is really just a roundabout and difficult way to say something simple. This is why it's so hard to accept new students because it's such a mean world.

And more recently, object thinking....
In the past, it used to be a single craftsman starting a business,
but now they're hiring more and more people to create big programs,
and they're creating more and more departments that work in a more organized way.

The world of programs, like the real world, has rules and common
sense within it, and it is simply the difference between whether
or not they are stored in computer storage.
It's supposed to be a simple story, but for some reason
there's a unique atmosphere that doesn't accept first-time students.

The more the world becomes an IT society, the more these advanced
engineers seem to be rolling out their technology in their own place.

That's why I want to make a hole in the world where this kind of climate is so prevalent.
