Riding the wind of rebirth

Chapter 749

The machine-readable card uses an OCR photoelectric head to collect information. There are 160 questions on a question card, and each question has four options. There are [-] areas to be collected in total, and the areas are irregular.

The dot-matrix area is simpler than the machine-readable card, with four squares, but there are [-] areas to be collected, and the accuracy is much higher than that of the machine-readable card.

In addition, there are other additional information that need to be collected. These information are mainly used for stroke coupling by the computer. For example, in the case of Chinese characters two and italic, the short horizontal line is a small pointed tip, and the long horizontal line is a short pen tip. These are used in coupling When rendering, there is a difference.

"I have completed the adjustment. The accuracy of the OCR optical head in the computer room is high enough. I have adjusted the scanning area and the number of dots. Now as long as the compilation is passed, you can run it and see."

"Huh?" The student sneered, "Stop bragging. I haven't heard of anyone who can compile a large program in one pass."

Before he finished speaking, Zhou Zhi quickly tapped the keyboard a few times and gave the computer a compiling command.

Compilation is a process, and the debugging log keeps turning up and down on the screen, and you can actually see the progress of the compilation.

Finally, the computer beeped, and the cursor stayed behind the string of characters "compiling succeeded".

"Success...success?"

"It was a success?"

"Successful?!"

A group of students had already gathered behind Zhou Zhi, all of whom were whispering to each other.

"Elbow, where did you learn this?" Li Hongjiang couldn't believe it.

It is not unheard of that a large program modification can be passed at one time. Back then, Bill Gatesto’s little partner sent the code to IBM headquarters for acceptance. The little partner found that there was a problem with the code on the plane, so he temporarily modified it on the plane. After getting off the plane and arriving at IBM headquarters , Send the program to the server, and compile it once.

This is one of countless great legends in the history of Microsoft, but there are really not many such examples.

"I simply adjusted the parameters, modified the scanning area, blocked some unnecessary branch programs, and changed the output and storage passwords..." Zhou Zhi said: "The topic structure of the program has not been changed, so...it's not complicated."

A group of people around looked at each other in blank dismay. The most difficult job for programmers was not to write their own programs, but to understand other people's programs.

This is also the reason why the ISO system places great emphasis on log files and comments for program development. You have to spend a lot of energy and time taking notes in the program and telling others what you use this program for.

Of course, this approach is an absolute luxury when storage space is extremely scarce. Every bit of computer space is used for code, and it is absolutely impossible to leave it for you to write logs.

Therefore, the person who can understand the program in such a short time, modify it, and compile it in one go is either the developer himself, or... a genius.

"My dad's work unit has a computer. It was my dad's joint office work and he was commended by the province, and he was rewarded." Zhou Zhi had already thought about how to word it: "It turned out that the computer was a second-hand product, and the old system was UNIX+ C, and then format a piece to install DOS."

"Because the nominal size of the hard disk is different from the size of the system space, the space has shrunk severely. The provincial bureau thought that two-thirds of the computer whose hard disk was broken was eliminated to my dad's unit."

"And then you found out?"

"That's right, I checked the BIOS and redid the boot disk, so I can play the UNIX+C part."

This problem is a bit more complicated. UNIX and DOS are two different operating systems. The UNIX system can draw a partition for DOS formatting and install the DOS operating system, but not the other way around.

Even undergraduates majoring in computer science don't know how to play these games, and most of the computer technicians in the Provincial Industry and Commerce Bureau are the kind who become monks for surprise training halfway through, and I'm afraid they don't even know how to do it.

But the provincial bureau is not short of money, if it is not suitable, it will be eliminated to the next, and it is better to replace it yourself.

This thing is true, and it often happens in this era. When Zhou Zhi went to work in his last life, he once encountered people in the work unit who could not initialize the modems. As a result, many modems with different passwords could not complete the handshake communication. In the case of damaged equipment being disposed of in the warehouse.

After Zhou Zhi initialized the modem, he used these "bad devices" to complete half of the unit's network construction, saving a lot of money for the unit, and the unit leaders were shocked by this freshly graduated college student, and directly allocated a set of welfare housing for him .

Like English, UNIX+C is something that has been played for decades in the last life, and it is hard to forget.

What's more, the core program of the machine-reading card is not complicated. Zhou Zhi quickly found the parameter part, completed the modification, and compiled it in one go.

"Old Mai, Professor Li, why don't we try?"

"Try it!" Li Hongjiang happily opened the carton: "Let's scan one and try."

The size of the card reader and the A4 paper do not agree. Although Zhouzhi has debugged it, the hardware itself is not matched.

Fortunately, it is still possible to read a dot-matrix character. Zhou Zhi folded the code paper in half twice. Li Hongjiang instructed the students to turn off the continuous reading function of the card reader, and then put the folded code paper into the card reader.

After typing the command, the card reader started to move.

Immediately afterwards, a box appeared on the computer screen, thirty times thirty, and then a small cursor began to jump backwards from the first grid position, and after jumping to the end of a line, it jumped back to the first line of the next line. One location, start over.

"So slow?" Mai Mingchuan had already dragged a stool and sat beside Zhou Zhi.

"I adjusted it so slowly on purpose. Now it's the debugging and monitoring stage." Zhou Zhi said: "There will be no such section when the program is officially running, and it will be scanned and stored directly."

Mai Mingchuan nodded and stopped talking.

After a while, the first illuminated grid appeared on the screen, followed by the second, and the third.

"Also!" The computer room burst into cheers. Even if the students didn't know what Zhou Zhi was doing here before, they now know.

This is a scanning program that scans the text on that piece of paper into the computer system.

This is not a complicated program in itself, but it is so pleasing to watch the small dots of light gradually turn into a word on the screen.

In addition, this program was independently modified by a teenager who looked like he was only in high school, and he compiled and successfully ran it once. The more expert you are, the more you know how difficult it is.

On the contrary, Mai Mingchuan has no doubts about Zhou Zhi, genius, who doesn't have one or two?
The key point is that Zhou Zhi's proposal on the large font library in the morning would never have been proposed if he hadn't been someone with certain attainments in information technology.

Before, I couldn't figure out how a young man in a small county could do it, but now I understand that this child is really familiar with information technology.

Soon, the small cursor reached the last grid, and a standard dot matrix "and" appeared on the screen.

"It's really done!" Li Hongjiang patted Zhou Zhi on the shoulder behind him: "What a boy! Really amazing!"
