Chapter 7: Lao Li's Test of Lu Yu

Chen Qiao arrived at Mo Du Electronic Science and Technology University, but he couldn't even step through the school's gate.

"Come on, hurry up and take me to see that kid." Lao Li had already been waiting at the school gate; seeing Chen Qiao's car, he jumped straight into the passenger seat.

Talent is the primary productive force!

Age often determines the upper limit of development.

A programmer who reaches industry elite level at seven years old, and a programmer who reaches industry elite level at twenty-seven— which one has a higher ceiling?

Chen Qiao's mouth twitched violently; he thought he was excited, but Lao Li was even more excited.

Where is the supposed arrogance of a prestigious school's principal?

Where is the supposed reserve of a prestigious school's principal?

……

Chen Qiao originally wanted Lu Yu, who had come after a long journey, to rest properly, but Lao Li was too enthusiastic, so he also wanted to give him some face.

At that moment, Mo Du Old Restaurant.

Little Lu Yu looked around curiously, while Lu Yu's mother, He Sui, shrank her body, being cautious and timid.

There was no way; due to poverty, He Sui had never been to such an old-fashioned, elegant restaurant.

Is this table before us, which looks extremely old yet carries an air of nobility, an antique?

Is that vase beside it, with many patterns and bright colors, a piece of blue-and-white porcelain?

Dong dong dong!

The knocking sound rang out.

Chen Qiao and Lao Li walked in together.

Chen Qiao and Lao Li first exchanged pleasantries with He Sui for a while.

Of course, He Sui could only nod blankly now; her eyes were filled only with confusion.

The principal of Mo Du Electronic Science and Technology University?

Grand's Director Chen?

He Sui wasn't well educated, but for Lu Yu's future she had also learned about some well-known universities in the country.

Moreover, she originally worked as a cleaner at Grand's branch, so she had long heard of Chen Qiao's great reputation.

In her heart, these two people are as lofty as the heavens.

Before these two, she didn't even have the courage to utter a word; her body was trembling, trembling.

At this moment, the two were squatting down, smiling as they spoke to Lu Yu!

Mo Du Electronic Science and Technology University student: This isn't the principal I know! Where is the promised respect for teachers?

Grand employee: The Director Chen I know has never been this approachable; this is a fake Director Chen!

……

"Little Yu, what do you know about Java and C languages? Feel free to speak." Lao Li asked a professional question right off the bat, and...

Too broad!

No beginning, no end!

This kind of question is the hardest to answer.

It's like someone asking: What are your views on domestic economic development?

If you talk big, it's just... bragging, which will make people laugh at you.

If you talk small, it's... lacking insight!

Lu Yu's big eyes blinked, speaking in a childish voice: "These two languages actually stem from the same logic; to talk about their pros and cons..."

"Actually, one can only say that different choices must be made depending on the application environment, right?"

This...

This is really outrageous!

Lao Li looked stunned, turning his gaze to Chen Qiao.

Chen Qiao was also full of shock.

Such an answer would naturally be nothing special to a veteran programmer who's been in the field for over ten years, but these words came from a child's mouth!

Whether it's professional or not is one matter; what's important is... the big picture!

Lu Yu is completely standing outside Java and C, or rather outside the entire network, to be able to say such things!

What is this?

This is spirituality!

However, just this isn't enough!

Maybe this is just a stock phrase that Lu Yu saw in that book or heard from some people and happened to use.

The coincidences in this world are just this unimaginable!

……

"Little Yu, Grandpa has another question for you. What is 79 times 86?"

Lao Li pondered for a moment, then posed the question again.

For programmers, mathematical calculation ability is important, especially mental arithmetic, as writing many functions relates to calculation.

"6794." Lu Yu blinked his big eyes, almost seamlessly continuing!

Lao Li and Chen Qiao both froze, then glanced at each other; obviously... they hadn't been able to come up with the answer right away.

Then... Lao Li embarrassingly coughed once, pulling out... his phone.

He used the phone's built-in simple calculator to compute it.

Cough cough...

Chen Qiao also couldn't help but cough.

Lao Li's face turned slightly red for a moment.

But he still quickly calmed down; a little embarrassment is nothing compared to possibly gaining a peerless genius!

Psychological Endurance!

Lao Li looked at Lu Yu again, his smile widening, and said: "Xiao Yu, the question I'm asking this time might be relatively difficult; you can take your time to think it through before answering."

Chen Qiao became serious and started!

Lao Li's formal assessment!

Lao Li took out a notebook from his pocket and then wrote /**/ on it.

"Do you know what this means, Xiao Yu?" Lao Li looked at Lu Yu.

Lu Yu lightly nodded, "The most basic multi-line comment."

Lao Li lightly nodded, not surprised, after all this is just the basics; although... this basics is already heavenly scripture to laypeople.

But Lao Li's expectations for Lu Yu are too high!

Lao Li wrote a line of code in the notebook.

"Program10.7Readingandunreadingcharacters#include#include#define bool int#define true 1#define false 0#include const size_t LENGTH = 50; /*Functionprot"

"Can you explain what this line of code means, Xiao Yu?" Lao Li looked at Lu Yu with a serious expression.

"Lao Li, isn't this... a bit too much?"

"Little Yu has been on the vehicle for a long time; he must be tired. Otherwise... let Xiao Yu rest well and continue tomorrow..."

Chen Qiao frowned tightly; Lao Li's written code exceeded the limit!

This code can be categorized under C++ language.

Although C language and C++ stem from the same logical foundation,... after all they are not completely unified, so the difficulty can be a level higher.

Lu Yu is merely a seven-year-old child!

"This must be code written in C++ language, right?" Chen Qiao's voice cut off, because Lu Yu had already spoken.

Lu Yu's voice still sounded childish, yet... his pronunciation was clear, neither hurried nor slow!

More importantly, with a single sentence he broke through the trap set by Lao Li!

Chen Qiao couldn't help but gulp nervously, not daring to breathe, just staring straight at Lu Yu, afraid to interrupt his description.

Lao Li's eyes widened greatly, his eyeballs seeming about to pop out.

"This is the control code for the basic process, returning flow input flow..." Lu Yu began to speak at length.

He not only precisely explained the meaning of this code, but even...

Lu Yu also took the pen from Lao Li's hand and began to write and draw in the notebook.

In less than ten minutes, Lu Yu had already written two pages of code.

"Programming languages are actually this world's most loyal friends; you give them what they are, and they become what you give them."

"Their changes, their calculations, their results all vary according to our intentions."

"Moreover, look at their structure; just these few lines of code are truly... perfectly symmetrical."

Lu Yu's voice remained a childish tone, but at this moment...

Each word that fell from his mouth was like thunder to Lao Li and Chen Qiao!
