At the end of the lesson, Wang Yufei had already identified the project he needed to learn in order to achieve his goal, programming, and set a specific goal for the first step, which was that he needed to be proficient in at least three computer languages in a week.

That's right, Wang Yufei decided to learn to do APP development.

It takes half a month to learn the language, choose the APP solution, make the finished product, and release the program as an individual developer, collect various data for testing in the next half month, and get the harvest in the next month.

The 23,000 yuan invested by Lu Yuxin can be used to buy various books for learning, develop software, and several mobile phones for testing, and if there is any leftover, it will be used for advertising after the APP is completed.

Of course, given the payment mechanism after the APP is launched, you may not be able to get cash in two months. However, it won't be too long. This is the best judgment that Wang Yufei felt made after gaining enough information.

As for why it is necessary to learn at least three languages to develop an app, it is because of the conclusions drawn based on various information on the Internet. At present, there are two mainstream mobile operating systems in the world, Apple's IOS and Android.

The front-end of Android applications is mainly based on java, so java must be learned, while the front-end of Apple's IOS system is mainly based on object-c, so OC must also learn.

The language of the backend server of the two systems is similar, and Wang Yufei decided to choose PHP, which is easier to use.

That's right, Wang Yufei's plan is very simple, next he has to use almost all of his time to learn and design an APP, and make two versions of Apple and Android, and from the design of this product to programming to the completion of packaging and uploading, all are completed independently.

In other words, Wang Yufei decided to do all the work of a product manager, programmer, tester and salesman by himself. Of course, if possible, or Lu Yuxin can also help......

"Xiaoyi, can I discuss something with you, move your computer to my room and borrow it for me for a while?" After making up his mind, on the way home from self-study at night, Wang Yufei opened his mouth to discuss with Guo Xiaoyi.

"What are you going to do?" Guo Xiaoyi looked at Wang Yufei curiously and asked softly.

"I want to learn some computer knowledge and then design and develop an app myself. Wang Yufei replied truthfully.

"Design and develop an App!Cool, what type of App do you want to design?" Guo Xiaoyi suddenly became interested.

She did not question whether Wang Yufei could succeed, and in two days, Wang Yufei had successfully erected an invincible image in the mind of this little girl, who was almost omniscient and omnipotent.

"I haven't thought about this yet, and I still have to analyze the market after the development language learning before I can make a final decision. Wang Yufei explained honestly.

"Okay, I can promise to lend you the computer, but when your APP is ready, I must be the first to use it!" Guo Xiaoyi rolled her eyes and made her own request.

For her, it really doesn't matter if the computer is in her house or Wang Yufei's house. Anyway, it's not the winter and summer vacations, and it's usually impossible for the queen mother of her family to let her use the computer, but it is good to give it to Wang Yufei, after all, this guy has to have a password if he wants to use it every day, and Wang Yufei has a password......

It is much more reliable to go to my brother's place to play on the computer on holidays than to get a password from the queen mother.

"Even if you don't ask for it, you'll have to pretend it first. Wang Yufei smiled happily: "You use an Apple mobile phone, and when I design the APP, I can use your mobile phone to test it." ”

"Cut...... Forget it, I'm too lazy to bother with you, but let me tell you first, although the computer is in my room, but I don't have the boot password. If you want to be able to use a computer on a regular basis, you have to get the permission of our Queen Mother first. I can't help you with this!" Guo Xiaoyi patted Wang Yufei on the shoulder and said like a little adult.

There was no schadenfreude to see the lively mood, because Guo Xiaoyi knew that as long as Wang Yufei made a request, the queen mother of the family would definitely stand on Wang Yufei's side.

Even if my mother refuses, my father will stand on Wang Yufei's side.

After all, this simple guy can really earn face for the two adults in the family!

Wang Yufei didn't pay attention, but Guo Xiaoyi, who participated in the open class, looked back at her parents from time to time when she was listening to the class. In Guo Xiaoyi's opinion, these two adults couldn't close their mouths with a smile.

Fortunately, she is her own daughter, Guo Xiaoyi even suspects that if Wang Yufei is born to the two, these two adults are afraid that they will directly put themselves in the cold palace.

"Well, I know this, I'll discuss it with Aunt Han when I get home. Wang Yufei nodded.

Wang Yufei is also very confident in persuading Han Qian to let him use the computer on a regular basis.

After all, he's used to do business, not to entertain. And he is confident that he will not delay his homework in junior high school, after all, he has almost learned.

......

Sure enough, after arriving home, when Wang Yufei reported his thoughts to Guo Jianfeng and Han Qian, the two agreed to put the computer in Guo Xiaoyi's room in Wang Yufei's room. He didn't even have time to mention that he was developing an app to learn computer languages.

In fact, Han Qian originally had quite an opinion about Guo Jianfeng buying a computer for Guo Xiaoyi.

After all, Guo Xiaoyi doesn't use much time now, and spending more than 6,000 yuan to buy a computer not only does not play a role, but may also affect the child's learning. But who makes the father cherish his daughter very much, he couldn't stand Guo Xiaoyi's soft grinding and hard bubbles, so he nodded and agreed.

For this matter, Han Qian was also angry with Guo Jianfeng.

Now Wang Yufei needs it, and he can make the best use of it.

In fact, Han Qian really doesn't care that Wang Yufei uses his spare time to surf the Internet every day. After all, this child's speed of mastering knowledge is amazing, in Han Qian's view, what restricts Wang Yufei's development in the future is not the mastery of knowledge in the classroom, but whether his horizons can be broadened.

Although the information on the Internet is too complex, there is no doubt about its role in broadening horizons.

It wasn't until the computer was transferred that Han Qian told Wang Yufei the password that she subconsciously asked, "Yufei, why do you think about the computer?"

"Auntie, I want to learn computer languages and develop an app. Wang Yufei replied.

"Huh?" Hearing this answer, Han Qian was stunned.

"Don't worry, Aunt Han, I will definitely not delay my studies. Wang Yufei solemnly promised.

"No, why did you suddenly want to develop an APP?" asked Han Qian.

"Well, it's a little secret, when I really succeed, I'll be the first to tell you, okay?" Wang Yufei said sincerely.

No way, the teenager is still too shy.

After all, why develop an app is a long story. He's involved in a promise of love!
