Riding a bicycle, Chen Hao and the four of them walked to the dormitory.

Now, Chen Hao has also bought a bicycle and has become a car owner.

"Chen Hao, what do you think of this freshman ball?" Ye Rong asked.

"Sit and watch, if there's a seat." Chen Hao replied to the question.

"Damn, I'm asking you what you're going to do?" Ye Rong complained.

"What can I do, I'm just a ** silk, I can't dance."

"How many of the freshmen do you think can dance? Actually, it's just going to have fun. Senior Sister Deng said that the freshman ball was very interesting, and she should participate in it a lot. Tong Fei interjected. But it makes a lot of sense.

"Then let's go and have a look. Alas, I'm still a junior brother, I haven't seen much of the world, dance parties or something, it's too high-end. Here, Chen Hao feels like he has returned to before high school.

Chen Hao's cuteness was despised by several people. Suddenly, there was a coquettish laugh from behind. Looking back, several people felt a heartbeat.

"Liu Qianqian! Why didn't she know in the back, what a failure, wasting such a journey. When a few people thought about it in their hearts, they suddenly wanted to beat their chests. But soon the laughter came, the distance ahead wasted the opportunity to get along, isn't there still half the way behind?

"Liu Qianqian, I didn't expect to meet you here, what a coincidence." Although Tong Fei is a rural child, he does not feel inferior because of this, but seems to be more coquettish.

"Coincidentally? Why don't I think, don't you see that there are so many people? Liu Qianqian looked at the traffic around her and said calmly.

"Aha, yes, I didn't expect everyone to be so coincidental today?" Tong Fei is not easy to talk to, so he picked up the conversation with a haha, although it was a little shameless.

Seeing that Liu Qianqian didn't mean to speak anymore, it was not easy for a few people to talk to others excessively.

But even if it was just that, after Tong Fei returned to the dormitory, he bragged endlessly, and finally talked to Liu Qianqian. Alas, it is so hard for this poor child to go to school here.

The next few days of classes were not very interesting, and Chen Hao studied in the dormitory. When he finished turning over the computer textbook, Chen Hao was still unfinished, this study was in full swing, but the book was gone, and he felt unhappy for a while.

Learning is more and more flavorful, Chen Hao originally thought that he could learn programming as soon as possible, but it is not enough to read these two basic books, C language and Java are both subjects he wants and must learn.

If you're not happy, go to the library. After looking at the time, it was only seven o'clock in the evening, and it was the time when the large army went to the study room or the library to study. It was violated when the door was closed, and now Chen Hao doesn't have to go out to check whether he has a campus card, because he is in the Sumeru space. Although it is overkill, this artifact of traveling and destroying corpses can only be temporarily wronged.

There are many libraries in Tsinghua University, including the old library, the new library, the main library, and the branch library. It's a pity that the Department of Computer Science doesn't have its own special library branch, so Chen Hao can only choose to go to the main library to have a look.

There are a lot of people in the library, and if you look at the bicycles below, you can see that there are many people who come here to study.

The library is very large, according to statistics, there are now more than 4 million books in the collection here, including many ancient books and thread-bound books, periodicals, doctoral and master's theses, it is simply a huge treasure of books.

Finding the bookshelf of computer books, Chen Hao quickly browsed it. Well, this is a C programming. As a programming language developed in the 70s of the last century, it is an old-timer and a basic tutorial for beginners. The foundation is very important, so choose it, the old thing may seem a little behind now, but it also has its essence.

I also chose a copy of C++, which is a very widely used computer programming language. C++ is a general-purpose programming language that supports multiple programming paradigms with static data type checking. It supports a variety of programming styles such as procedural programming, data abstraction, object-oriented programming, and generic programming.

Seeing that Java Chen Hao also won, Java is the most popular programming technology today, and it is the general name of the Java programming language and Java platform (i.e., Javase, Javaee, Javame) launched by Sun. Java technology is widely used in personal PCs, data centers, gaming consoles, scientific supercomputers, mobile phones, and the Internet, and has the world's largest professional community of developers.

As a computer student and a software student, Chen Hao is no longer limited to the Internet in the computer field as he was in middle school. A lot of general knowledge problems in computer science are understood.

When it comes to computer programming and network technology, many people think of hackers. Hacking techniques, simply put, are the discovery of flaws and vulnerabilities in computer systems and networks, as well as techniques to carry out attacks against those flaws. The defects mentioned here include software defects, hardware defects, network protocol defects, management defects and human error.

Discovering and implementing hacking techniques usually requires a person to be very proficient in computers and networks, and discovering and verifying a computer system vulnerability can require a lot of testing, analyzing a lot of code, and writing programs for a long time, which is not much different from a scientist working in a lab.

What Chen Hao has learned now and what he will do in the future will inevitably face these problems. The only thing you can do is to learn more than others, and write programs and make software that makes it not so easy for others to crack. If you progress faster than others and improve faster than others crack, then others will not be able to exploit your loopholes to make a fuss.

After taking several books, from beginner to proficient, as well as related exercises, Chen Hao decided to understand these contents first, and it was not too late to learn the other courses before the exam. College is different from high school, and it is not enough to just look at the grades, but also to look at the operation. A university is a place to put what you have learned into practice, especially Tsinghua University. There are more graduate students than undergraduates, and what they need is to be able to apply what they have learned.

Chen Hao is different from others, whether it is in terms of learning speed, learning scope, or learning depth, he feels that he must be stronger than others, otherwise why should he make achievements for the computer career.

With a few books, Chen Hao couldn't wait to learn, or just read it in this library for a while, anyway, he went back to the dormitory to learn, just to experience whether it would be more efficient to study in this library full of learning atmosphere.

Coming to the place for studying, since he found that there was no place, Chen Hao had to change places to see, this library, which claims to be able to provide 2,000 people to study, should not be unable to find a place.

Well, there's one more location here. One floor down, Chen Hao finally saw an empty position here. Although there is no one in some seats, but there are schoolbags, books or something, it also means that there are people, this unspoken rule is here, and Chen Hao is not good at occupying other people's seats. Fortunately, there are no books in this position, but there is a book in the position next to it, which should occupy a place, maybe someone else helps, or maybe he walks away temporarily.

There are a total of six books, Chen Hao gently put them on the table, so as not to disturb others, picked up a book in C language and began to read. This kind of learning environment that is in a sea of people, but quiet as no one, can really give people a different feeling. Just like in a game, learning in the library can increase the speed of learning, which is a wonderful effect bonus.

Speaking of learning madmen, those who only read the books of sages and sages with their ears do not listen to things outside the window. Chen Hao was fascinated by reading books, devoted himself wholeheartedly, and his learning speed was fast, and he turned over all of a sudden.

Liu Qianqian came to the library today to look for materials, she still didn't understand the content of the math class in the afternoon, and the homework after class had not been completed, so she came here to find some materials for reference. I went to the library, put down my books and took a place, and then went to look for materials.

When I came back, I saw that there was only one seat left at the table for four people, and two men and one woman were sitting in the other three seats. She turned her head and looked around, trying to find a seat full of girls. But I found that there was no location, and it was normal to find a location at this time. After thinking about it for a while, I can only sit in this position.

Liu Qianqian sat down and didn't attract everyone's attention, everyone here is immersed in studying, even if they see someone they know, they rarely go up to say hello, they don't want to disturb everyone's study, and they don't want to spoil the atmosphere here.

In serious study, time passes quickly. After reading the fourth chapter, Chen Hao finally knew how to write a simple and complete program in C. Seeing this, it can be regarded as a great gain. I looked up and found that the two people sitting opposite were gone, and there were a lot fewer people around, so I don't know what time it is.

I was about to take my mobile phone out to take a look, but when I turned my head and saw the person sitting next to me, Chen Hao was suddenly stunned. Isn't this Liu Qianqian?

Liu Qianqian noticed Chen Hao's gaze, turned her head, and found that this person was still the person she had met twice. She didn't know Chen Hao, but she had met twice, the first time was when she was in the sports field, and Chen Hao made a deep impression on her. The second time was on the school road, she rode a bicycle and followed Chen Hao, and when she heard Chen Hao's self-deprecating joke, she couldn't help laughing. caused Chen Hao and several people to turn back, and Liu Qianqian also recognized Chen Hao as the person on the sports field.

It's just that I didn't expect that just a few days after the start of school, the two of them met again in the library.

"What a coincidence, I didn't expect to meet you here." Chen Hao took the initiative to say hello, but his voice was not loud, after all, there were still people learning.

"Well, hello. Are you leaving? "Everyone is an alumnus, Liu Qianqian has an impression of Chen Hao, and it is not appropriate to pretend not to know them at this time.
