Reading as a god

Chapter 14 Pointers, pointers?
Zhang Shan quickly regained her composure. Ever since her parents left, Zhang Shan has silently believed in the principle that what she has now is the best.

Zhang Shan looked at the prompt in the system:

"The current system level is level 4, and the experience required to upgrade is 784/191"

Zhang Shan made a rough calculation, and according to the speed at which she has accumulated experience, it will take more than six hours to upgrade to level 5.

Although you can directly spend money to upgrade, but before Zhang Shan spent 30 to upgrade various learning and even things that were not close to learning, Zhang Shan couldn't think of what to buy for a while!

Zhang Shan simply didn't do it deliberately anymore!
……

"Huang Xin, why are you transferring 300 to me? Didn't you agree to treat me to dinner?"

"Almost half of the people in this activity didn't stick to it, and then the 'Azure aardvark' simply gave us 600 yuan each."

Jiang Xue couldn't help but asked curiously: "That's right, did you see that 'Azure aardvark'? Is it handsome?"

"Wow! Jiang Xue, let me tell you! I think I'm in love, that person is so handsome, I'm so crazy when I laugh~"

"Yo yo, our Huang Xin is also a nympho this day, it's not easy!"

"Tch, you still say I'm a nymphomaniac, isn't it time for you to run around chasing the computer science brother?"

"You two can do it, don't make noise, let me sleep for a while!"

"Li Yaoyao, when did you come back? Why did you appear and disappear like a ghost? How about Chu He, didn't you come back with you?"

"No, she's gone home." After Li Yaoyao finished speaking, she buried her head in the quilt!
"Laziness!"

……

"Zhang Shan, you're back, how are your activities going? I see someone complaining about your activities in Shuimuyuan, it's not something people can stick to!"

"It's so mysterious, 16 people persisted. How do you arrange your weekends? Where did Lin Yuan and Li Ke go?"

"Going to accompany my girlfriend."

"What about you? Don't you have a girlfriend too?"

"I can't explain it to you."

Zhang Shan was baffled by what he heard, so he simply ignored Huang Xu, took out the "National Computer Rank Examination Level 2015 Tutorial - C Language Programming ([-] Edition)" and read it, although Zhang Shan also learned programming two days ago Aspects, but basically just a review of what I read before.

Zhang Shan now sees Chapter 6 - "Character Data".

Zhang Shan quickly entered the state. This chapter mainly introduces five aspects:

（1）字符常量与字符变量（2）字符数据的基本运算（3）字符数据的输入和输出（4）用于字符数据的基本函数（5）字符处理的有关算法。

According to the description in the book: "In C language, a character constant represents a character in the ASCII (American Standard Code for Information Interchange) character set, and a character is enclosed in single quotation marks in the program as a character constant"

Zhang Shan conveniently checked it on the computer:
"The so-called ASCII character set is a standard single-byte character encoding scheme for text-based data. It was originally a US national standard for different computers to use as a common Western character encoding standard when communicating with each other , and later it was defined as an international standard by the International Organization for Standardization.

A total of 128 characters have been defined so far, and most of these 128 characters are displayable characters. "

Zhang Shan was at a loss!Zhang Shan simply searched for the syllabus of the Level [-] C language test in previous years.

Zhang Shan looked it up and found that none of these outlines had specific examples, and the words 'basic requirements' were written crookedly on each line.Zhang Shan couldn't understand anyway, and after looking carefully for a long time, she finally saw the way through the details. All the descriptions of ASCII codes in the syllabus were written with three words 'Memorize it! '. "

Looking at the various ASCII code values, say:
The value of the character constant 'A' is 65 (the following parts without special prompts are all decimal numbers)

Alphabetic character 'a' has value 97
The numeric character '0' has the value 48
The value of the space character '' is 32
At this time, Zhang Shan only lamented that the system was awesome, and there were nearly 70 ASCII codes to memorize in the exam. Without the blessing of the system's excellent memory, Zhang Shan would never be able to do it all in one go.

In general, the chapter "Character Data" needs to remember a lot, but in fact it is not particularly difficult.

Chapter 7 is devoted to "functions". On the one hand, it introduces the functions that were not introduced in the previous chapters, and on the other hand, it introduces how users should define and describe functions and how to call such functions.

Generally speaking, this chapter is not very difficult. Chapter 6 and Chapter 7 can be completed in two hours.

Zhang Shan recalled that when he was studying the first seven chapters, it seemed that the road ahead was flat!

In many cases, reading is a journey of one person, and it is necessary to give yourself some encouragement.

Zhang Shan couldn't help but secretly praised herself, it seems that my brother is still very talented in learning computers!

……

Hearing the teasing laughter of Huang Xu and her girlfriend Lu Yiran, Zhang Shan couldn't help cursing all kinds of video calls as terrible inventions.

Zhang Shan originally thought that there was nothing lacking in his study, but now it seems that there are too many things missing, such as anti-noise earplugs, anti-noise earmuffs, anti-noise
But what is most lacking is a weapon that can eliminate noise at the source! ! !

How annoying!

What is even more disturbing is that Zhang Shan remembers that she has been watching Chapter 8-"Address and Pointer" since 09:30 in the evening, until [-]:[-] in the evening.

It's not that it's difficult to move an inch like the first time I read "Mathematical Analysis", but I remembered it after reading it, and then I seemed to understand it and then I didn't seem to understand it!
Is this the legendary Schrödinger's pointer?

Zhang Shan is no longer entangled, the knowledge in the university has never been point-to-point, and I know too little about the bottom of the computer, so this kind of problem arises.

Zhang Shan took a look at the system:
"The host can earn RMB 1 for every minute of reading"

"The host read for a total of 150 minutes, accumulatively harvested RMB 6000, and accumulatively gained 6000 experience"

"The current system level is level 4, and the experience required to upgrade is 790/191"

At this time, the phone rang, and it turned out to be Hanxue's WeChat message:

"Student, you won't want to pigeon me again today, will you?"

Zhang Shan's eyes lighted up, and if she had a problem, she asked her senior sister.

"Senior sister, the address and pointer of the second-level C language I read today, are you familiar with the pointer?"

It took Han Xue a while to send:

"Student, don't you want to take the C language test for computer level 9? In fact, you only need to thoroughly understand the first seven chapters, and then understand the basic content of Chapter 10 arrays and the simple application of Chapter [-] strings. You will have no problem passing it!"

Zhang Shan: "."

Zhang Shan can see that although the senior sister is very motivated, it is obvious that her ambition is not in the computer itself.Take the route of overseas returnees with a bachelor's degree and go back to China to find a well-known IT paddle.

But girls naturally have advantages in this regard, and IT is also willing to recruit this kind of prestige.

With beautiful programmers, why not attract a bunch of programmers!

　The contract has been mailed, and book friends are welcome to invest!
