Don't introduce, Houjie's name is the best introduction.

Re: How do beginners learn C [I see me smell me?

2000/04/22 Recent questions: "How to learn C ", "beginners", and trigger a long stroke discussion. Every day I sipped coffee, watching a long message, in the fineness and childish, far-reaching and shallow, screaming and arguing, although I have a tired body and mind, chatting, thinking that after the tea Capital. But look at the more than a lot of stipulations, I think of some problems, and my mood is not very easy.

I have some feelings.

● Don't swear

High school, good technology, although you can talk more macro, more powerful, more respect and understanding, others can't make trouble, but don't mean you can export. "Waste, idiot, scum, and ugly", these swear people are really unbelievable.

You can't swear, it is the basic etiquette of the Internet. "No" can be seen from both levels. In terms of law, it is not possible to be a gray zone on the Internet. Most of them will not appeal to the big movement. So, unless a celebrity is awkward, or the celebrity is swallowed, it is only a breeze, and the water wave is not happy.

I want to talk about "I can't swear" on the level of cultivation. I want to talk about the basic code of the Internet, just like talking about the basic truth of the people.

Some people conduct the "straightforward" principle, and it is necessary to nakely express their emotions and then fast, so that the etiquette, etc., or "false". The network is a world that does not appear, and it has a large number of "straightforward". But as I said, "Wen Ruo", the text shows the author's disorder, mood cultivation, and learning technology. Can I went wrong?

Gu Yun "The gentleman does not deceive the room", it means that although it is in the dark room of no one, it does not make a deceived thing (Tang Luobin Wang. Firefly: there is a way, into the dark room, not bullying) . This virtual world is like a big dark room. Although others don't want to see your true face, everything in your dark room is still loyal to yourself.

Yesterday, I would like to carry out the guidance of the school to listen to the courses. On the way, he just mentioned the Compospook version. I said out: I shouldn't be swear. The student said: But someone should be embarrassed.

Oh, really?

If this world is "the concept may be a bit deviation, the technology may be a little short, the attitude does not make you pleasing to the eye, then you said, then, the skills and art of the people have swearing, you are so rough this What is wrong, "" The concept may be a bit deviation, the technology may be a bit less short, the attitude is not allowed to be eye-catching ", but also?

No, you shouldn't be jealous. So he shouldn't be jealous.

To express sharp and sharp, there is another way; please don't use it, especially like "waste, idiot, scum, and ugly".

Or some people say that my personality is like this, and the straightforward is my motto. That is also dependent. I just said that the Internet is a world that does not appear, and it has a large number of "straightforward". I wrote this article, it is not that the author of the article is not affecting the author's article (I think I have no such ability), I want to affect the readers of the article - you.

How easy is it to accuse someone else, how it is not easy to review you. I think about my own article and have an emotional word. Although it is a proportion, which person is not particularly, I still feel a bit awkward.

● Text is like

Derivatives, I still want to say, the era of racing, and the bias of Taiwan education, causing the words on the Internet, the logic is not passing, the language is not smooth. Everyone is anxious, there is any idea to get out, online reply; not only do not read, even if you don't read the second time, press the button to send out. Text is like it. If you have a text that you will shoot-, you don't care, what do you care about? You care about only the resolution of the lighter. If you are in real life, you are in cautious, but in the dark room, you will remember that there are many courtesy of the people in the real society. , Flash is boiled, and there is a car and polite.

But you, it is you, only one you. Which is true you? Ask yourself in the middle of the night.

● How do beginners learn C

As a questioner, it has the ability to judge the experience from the reply content, and then estimate its correctness or applicability, and then determine your own adoption?

If it can, it will not ask this question. If you can't, you should don't have to ask this question.

On the Internet, the experience of these years, so that I can easily judge which topic has a good show, which one is to detonate the saliva and even the corners of the battle - and finally just a melee, the sieve is not a few guys. .

We thank the enthusiastic reply, they warmly provide their own experience, no matter what they are one year experience, three years of experience, five years of experience, ten years of experience. Whether you are 1/4 bottle of water or a half bottle of water, or 3/4 bottles of water or full of water.

I want to know, how to judge and pay these replies with the level of questioners?

Usually we seek this kind of learning (this is a very important and critical issue for yourself), should not ask a stranger, it is not enough. Because of the experience of strangers, I don't know anything, why is his learning? Is it worth following? You are unable to judge, there is no need to ask.

Why don't you ask your teacher? Your school? Your classmate? That is what you see, if you admire their abilities, you can ask their learning experience. Because you know their performance, you can decide your integration.

Is this not much more meaningful to the questioner?

● Three non-policies

Modern students have three non-policies: don't speak, don't answer, don't ask me. Whether it is in the university hall, or a company's training, I often face the silence of the silence, so I have learned that I have never been a field survey - I want to raise my hand.

Yes, there are people who don't even raise their hands. Any action that will expose any state, all reject.

This is probably why everyone likes to send us up. Oh, no one knows who I am.

The students are confused, don't like to ask in class, I like to ask under get out of class. I fully know the crux. Because your heart is struggling "Is this question? Tibet, don't expose it short. So, I asked the get out of class, and I didn't ask for it at all.

Some teachers answered certain levels of problems, they would bring the embarrassment or tone. This teacher should be responsible for the three non-policy negotiations of modern students.

I don't want to expose it short, it is normal human nature. So, what you should do is, pre-class pre-study. Only before class pre-study, or after class review, there is a level of confidence that you ask, isn't it? I really don't know how many students have a habit of pre-class pre-study. There is one in my class, I appreciate his positive.

I will let everyone bring the mask to class, and I have to guarantee that there is much more problem :)

● Ten times speed learning

As long as you maintain a principle, you can learn ten times.

Pre-class preview, after class review.

So, your absorption is in class, it is ten times that of others. Although the speed is an absolute value (there is no absolute universe), it is also a relative feeling. Your absorption is ten times that of others, then you are not ten times to learn, what is it? You spent an hour before each class, spend an hour after class, is more valuable than twenty hours before the exam.

But because of short-sighted, I can't see the future, I can't do it. Hey!

Pre-class preview, after class review. Old tone!

Although it is self-love, it will not bomb it today.

● Eye. 1

From a series of discussion in a series of C learning, the relationship between C and C , C 's ability is compared.

The problem of old traps!

Some people don't think C is better than C, think that others have strongly holding C because they have never seen the "C-skill", the "C language is high enough to imagine" monsters.

Yes, I am sure that all C can do, C is doing. "Inside THE C Object Model" (China "depth exploration C object model", Hou Junjie, peak 1998) or "The Annotated C Reference Manual" (without Chinese) book, put many C mystery (such as Object MODEL, VPTR, VTBL, TEMPLATE, INLINE ...) are exposed, and readers can even write a C compiler (of course, the direction is there, you may need to know more of more actual details).

Perhaps, the C compiler is completed in C language (I don't know).

So, what is C to do it? Can't do it?

No.

Inadvertently written a C library with a C compiler, there is still what is not available.

The problem is, "available" is not necessarily "best". Think about the cost of pay.

I have been in front of C , and my colleagues will sometimes listen to some courses. My Hui Ren is poor, even OOP can't turn; my colleague Huang is a good, and I can master OOP. As for OOA / OOD, we have all the nasal, privately threaten, those teachers who take the fog from high-speed, they don't understand.

But we only dare to ridicule each other, do not dare to express it. Even if it is expressed, it is also reserved, and there is a cyclone.

Because we know, there is so many people's research, so many people's praise, it is impossible to have no reason. We also know that you don't understand your own, afraid only because of your shallow.

Later I then lost interest to OO, change Windows (Programming & OS), and my colleague continued to be. Although he doesn't like reading, but C / OOP's book is a lot of K, and it is an expert in this field with personal excellent Programming Kung Fu.

I finally got to work hard when I was studying MFC, I have to work hard to engage in C / OOP. So I started learning C in order to use a set of C Class Library. To figure out some achievements (and because of your interest), you will continue to go to Object Model, Framework Infrastructure, Generic Paradigm. I will say it again, "I can use it" is not necessarily "best".

I will say another time, a technology, a paradigm, and get a multiplayer (can be said to be the entire industry), and it is impossible to have no reason.

When the eyes are not open, you must know that your eyes are not open, keep humble.

● Eye. 2

Ten years ago, I have the first car. So I started to know the various situations sitting on the driver.

One day I and a friend night to Jingmei Xiang Xiang Xiang, who took a friend's locomotive. The locomotive big light is broken, I am worried, I want to flash the direction of the light. He was ignored, and he said that the Taipei street lamp was so bright, we see others, others also see us.

But I know that the driving of the car will not see us from the mirror.

It is visible, but you have to look carefully. If you carefully see the anti-collective mirror, you can't see it in front of you, so the driver looks at the mirror. At night, there is only a light to let him go. He is not looking at there is no object, he is looking at the light.

I am glad that after the adventure night riding the locomotive without a headlight, I am still alive.

My friend didn't drive a car, so he didn't know this situation. I opened the car, so I know. This is what I and him at that time, the difference in the hierarchy of the transportation.

I opened a passenger car, so for seven-person cabin, nine-person cars can also be easily mastered, immediately go up. But I want to open 10 rounds of big goods, two tons and a half, even blame, I know that the obstacles on the order (ORDER) need to overcome. I want to open the plane, the obstacle to the level is higher.

The driving difficulty of the locomotive, as well as the travel distance, and a gap between 1 level. The driving difficulty of the car, as well as the travel distance, and the gap between the aircraft has n levels.

So we have no way to talk to the vast days in the frog in the well, talk to the sea of ​​the fish in the river, and talk to Yan Xiao.

But we must have a humble heart: in front of the higher level, we are the well frog, river fish and souk in their eyes.

--- The end
