(New book period, ask for flowers, ask for collection!) In the afternoon, when Xiao Yuan came back from home again, Tang Xinyu had already come first, reading the technical documents written by Xiao Yuan in the morning, and there was a thick dictionary at hand, which he opened and checked from time to time.

"Xiao Yuan, come over here and explain to me what this sentence means?" When Tang Xinyu saw Xiao Yuan coming back, he hurriedly beckoned, called him over, and pointed to a sentence marked with a red pen on the technical document and asked.

Xiao Yuan glanced at it and explained to Tang Xinyu, the sentence structure of this sentence is a little complicated, and some of the commonly used words in it are completely different in computer professional English, and the dictionary in Tang Xinyu's hand is just an ordinary Oxford English-Chinese dictionary, no wonder he can't understand it.

After listening to Xiao Yuan's explanation, Tang Xinyu looked clear and said, "No wonder I look at this sentence awkwardly, no matter how I translate it, I don't think it's right." ”

"You should get a professional English dictionary and you will be able to find out what these words mean." Xiao Yuan said.

"Well, you're right, but I'm afraid it won't work this week, so I'll buy one next week."

Regarding Xiao Yuan's suggestion, Tang Xinyu thought so, but couldn't help but sigh: "Xiao Yuan, your English is really what you usually learned when you read English materials, why do I think this is incredible the more I think about it?" ”

"Hehe, there are so many incredible things, the fact that your old man has to marry your sister to me can happen, and what else can't happen." Xiao Yuan said with a slight smile.

"Yes, forget it, I won't ask, I found that you are full of evil doors, everything that has anything to do with you, there are few normal things, you are busy, I will continue to read, if there is something I don't understand, I will ask you again." Tang Xinyu waved his hand and said, and continued to look down at the document after speaking.

What Xiao Yuan has to do next is to make the core of the firewall he is going to take out, and the tool he uses is the visualc++6.0 that Tang Xinyu found during the last CIH virus outbreak in the computer room, which should be the best development environment for developing Windows applications that can be found at present.

The firewall is different from the small tools with a single function that he developed before, the complexity and the amount of code are much larger, Xiao Yuan naturally will not use assembly for development, of course, he needs to deal with the bottom layer, or in order to achieve some special functions, assembly is still essential, but at this time, assembly is no longer the main development language, and the main language to be used to develop the firewall is C++.

Xiao Yuan first used VisualC++ to build a project, and did not rush to code, but saved the project first, and then turned off VisualC++.

Developing a fully functional system is an undertaking, and coding is not the heaviest part of the overall project, and a lot of preparatory design work is required before it actually goes into coding, which is more important than coding.

VisualC++ comes with some auxiliary design tools, although those tools are powerful, but there are also many limitations, which makes Xiao Yuan feel constrained to use, so he did not use those tools, but chose to use Word, completely manual design.

Although this design is only a reference for himself in the design, Xiao Yuan is still habitual, very serious to write a development document, the format used in this document is very standardized, it is no exaggeration to say that he spent an afternoon to write the design document, can be used as a model for some companies, or project teams to write development documents, so that Tang Xinyu, who came to watch later, sighed.

In the evening, Xiao Yuan added a little extra class, and in the evening, he wrote the document completely, saved the document on the teacher's machine, printed out a copy, and was about to leave with Jiang Hua, but was stopped by Tang Xinyu, and took the two of them to a restaurant outside the school for dinner, coincidentally, the restaurant they went to happened to be the one that Xiao Yuan took Gu Wolf to last time, which reminded him of Gu Wolf again, thinking about when his younger brother would not be able to have surgery, and at the same time thinking that it was not too late to eat for a while, and then go to the hospital to see.

Hearing that Xiao Yuan was going to the hospital, Tang Xinyu also proposed to go with him, so after the three of them had eaten, they set off to the hospital together, went to the hospital again, went to the gate of the hospital, put the bicycle away, and the three of them were about to go to the hospital, but they were surprised to find that Gu Wolf walked out of the hospital, there were two sturdy men on both sides of him, one left and one right, and when Xiao Yuan came to visit him on Friday, the man he saw followed behind them.

"Gu wolf." Xiao Yuan shouted.

Gu Wolf stopped, and when he saw that it was Xiao Yuan and them, a reluctant smile appeared on his face, and he said, "Xiao Yuan, it's really unfortunate, I went out to eat with a few friends. ”

The old man who followed behind Gu Wolf stepped forward, came to the middle of Xiao Yuan and Gu Wolf, and said with a smile: "Haha, since we are Gu Wolf's friends, let's go sit together." ”

"Something is wrong, pay attention to the men on both sides of Gu Wolf, they have guys in their arms, Gu Wolf is being held hostage." Jiang Hua said in a very low voice next to Xiao Yuan's ear.

Xiao Yuan was stunned for a moment, paid attention to the two men, and sure enough, he found that there seemed to be something in the jackets they were wearing, and he couldn't help but be a little worried about Gu Wolf.

"Xiao Yuan, you guys go back first, if there is anything, come back tomorrow." Gu Wolf said first.

"Jiang Hua, can you deal with those two people?" Xiao Yuan turned his head and asked Jiang Huadao.

"No problem, but it's not my job to deal with them, are you sure you want me to deal with those two people?" Jiang Hua stared at the two people and said.

"Gu Wolf is my friend, he is very important to me, you are helping me when you save him, where is there so much nonsense." Xiao Yuan said.

"Okay then, you and Teacher Tang step back, and I'll leave it to me here." Jiang Hua nodded and agreed, and after speaking, he took two steps forward, came to the place between Lao Yu and Xiao Yuan, stretched out his finger and pointed at Gu Wolf, and said to Lao Yu, "Leave Gu Wolf behind, you can go, otherwise you will break your legs." ”

"Damn, this guy is so arrogant." Xiao Yuan listened to Jiang Hua's words in the back, and was speechless for a while, and said in his heart that this guy didn't know how to be subtle when he spoke.

"Haha, this friend, you're kidding." The old man was also stunned by Jiang Hua's words, and then asked with a smile.

"Do you think I'm joking?" Jiang Hua took another step forward, looked directly at the old man, and said coldly.

The smile on the old man's face disappeared, became a little gloomy, looked at Jiang Hua and said, "Friend, I don't understand what you're talking about." ”

"Don't you understand, you're going to get it soon." Jiang Hua said with a smile indifferently, after speaking, he took a step forward and made a move that everyone didn't expect, he clenched his fist and hit the old man in the lower abdomen, the old man snorted, his body curled up into a ball and fell to the ground, unable to speak for a while.
