In order to solve the problem of machine code, which is difficult to read, in 1952, Mokley, Grace. Hope et al. have developed a kind of 'assembly language', assembly language is a major progress in programming language, which uses some symbols to form an instruction set, and those symbols are relatively close to the language and mathematical symbols that people say are common, so it is easier to write programs and read programs in this language than machine code. However, assembly language has a big disadvantage - different computers, even the same model, use different assembly language compilers."

Huang Tingjun explained: "Although assembly language has improved, it is still a less than ideal programming language for programmers. ”

For assembly language, Zhang Shaojie has long heard of its name. But I don't know the details, and when I heard it today, I realized that assembly language was like this.

Although Zhang Shaojie never forgets and does not need to take notes, in order to show a serious attitude, he naturally keeps recording Huang Tingjun's lecture notes.

Shaohuai is an honor student, with a strong memory, and he is interested in computer knowledge, so he absorbs it relatively quickly.

And Anita Mui and Mei Aifang are also more serious, but because of the amount of information, and because they hated their grades when they were in school, they struggled to study.

Of course, looking at the seriousness of the two Zhang Shaojie brothers, the Mei sisters did not admit defeat and listened carefully.

In the era of assembly language, a machine had a completely different set of assembly language rules. Programs between different machines are not portable or compatible. Therefore, at that time, the program was still the era of handicraft workshops, and there was no standardized programming language for mass production of programs.

In order to solve this problem, by the 50's IBM John . Bakers, developed a set of "FORTRAN language"!

Huang Tingjun emphatically said: "Fortran - it means formula compiler! This programming language includes 49 basic characters, 26 English letters, 10 Arabic numerals, and various symbols. Formula compiler, which can be independent of the hardware environment of the machine. A set of programming languages can be ported to different machines, and people call this programming language with a compiler 'high-level programming language'. ”

"After the advent of high-level programming languages, computer programming began to be no longer the preserve of computer scientists, but more and more ordinary people can become programmers by learning programming languages. Moreover, since the birth of high-level languages, since the 60s, not only computers, but also satellites in the sky, missiles and warships of major countries have adopted high-level programming languages for more flexible and free control! ”

"After the Fortran language, various programming languages have sprung up, such as the basic language, which is easier to get started, and the C language. Of course, among these languages, the one that is getting the most attention today is C, which is widely used and has a strong transplant surname, and can write all kinds of computer systems and all kinds of application software. I suggest that you learn basic and experience programming, C language is a programming language that is really worth learning in depth! Most of the programs can be written in C."

Huang Tingjun gave a lecture to Zhang Shaojie, which was much more serious than lecturing on campus. Because, when the school lectures, no matter whether the student learns well or not, he receives his salary. And Zhang Shaojie paid him to give a lecture, and if he was not satisfied, he would be dismissed directly. As a result, he began to be filled with a passion for lecturing

—————————— a week has passed in the blink of an eye.

It's 6 p.m. again.

Every day from half past six in the evening, Huang Tingjun would go to Zhang Shaojie's home and give lectures to the four of them.

The living room has been furnished like a classroom.

Blackboards, computers, desks

"Professor Huang, good evening!" Zhang Shaojie and others greeted politely.

Huang Tingjun nodded and said, "Good evening everyone, after a week of study, I believe that all of you have gradually understood electronic computers and programs. For modern society, computers have brought earth-shaking changes to everyone, and without programmers, the machines in factories would not be as advanced and automated as they are now. Nor can planes, satellites, ships at sea, and our communications be so smooth. Before the 70s, computers were just tools for large companies to process data, academic institutions for research, the military for national defense, and so on. And in the 70s, the popularity of personal computers, represented by Apple computers, had just begun. I believe that the popularization of personal computers will have a more profound impact on all walks of life in the world."

"Teacher Huang, I want to ask a question," Anita Mui said suddenly.

"Ask!"

"Does a computer affect movies, singing? Will it be in the future, only programmers are needed to write programs, and the programs will replace people in the computer to perform and sing? Anita Mui said.

Huang Tingjun nodded and said: "With the development of technology, it is indeed possible for computer technology virtual characters to perform and simulate human singing." For example, Zhang Shaojie, did you soon cooperate with Industrial Light & Magic to use computer technology to create special visual effects for films? ”

Zhang Shaojie nodded and said, "Yes!" It is precisely because I saw the creativity of American programmers that I realized that in the future, if you want to lead the trend of the times, you must understand computer technology and computer-related industries, so as to be able to promote the development of traditional industries with the help of the booming computer industry! ”

Everyone asked one question after another, and Huang Tingjun felt it deeply. Zhang Shaojie and others were pragmatists, and after learning computer knowledge, they quickly thought of commercial applications.

Because, the questions of Zhang Shaojie and others touched Huang Tingjun a lot. In the past, when Huang Tingjun started his business, he only saw the business opportunities of microcomputers, but did not consider why ordinary users need microcomputers.

Soon after, Huang Tingjun also realized that the success of Apple Computer was because it met the needs of ordinary programmers to write simple programs, so it was also a commercial success.

And the personal computer that Huang Tingjun made before was not clearly positioned, and users could not know what they could do when they bought it home, so it would fall into the sand!

Because Zhang Shaojie and others have won Huang Tingjun's recognition of their attitude towards the study of computer technology, he gradually regarded these four people as his disciples, and his teaching attitude gradually became more and more serious and strict.

However, because the four of them have different abilities to accept knowledge, there will soon be a difference in learning progress.

Zhang Shaojie's memory is the best, and because he has 30 years of experience in the future, he has a relatively strong ability to accept computer knowledge.

At this time, Zhang Shaojie was already proficient in using Apple computers and doing some simple software work. For example, using some table software, calculating and statisting financial data, and using computers to complete some office and printing work, it seems easy.

The younger brother Shaohuai made Zhang Shaojie feel pleasantly surprised, because after only a week of study, Shaohuai was able to use the basic compiler that came with Apple computers to write programs.

The software written by Shaohuai is called "Computer Manuscript Paper", Zhang Shaojie was a little surprised when he saw this software, this is a promising set of word processing software.

Whether it is the later Microsoft ORD, or China's domestic Kingsoft PS, it is a leader in word processing software. In the mid-80s, word processing software because of high efficiency, low cost, quickly set off an office revolution among many large enterprises, the vast majority of internationally renowned enterprises, quickly introduced microcomputers, word processing software into the office, "paperless" office once became synonymous with advanced and high efficiency!

It can be said that the profits brought by office software to Microsoft are not inferior to those of system software!

Shaohuai said: "Unfortunately, there is no Chinese text input software now, if there is Chinese input software." Brother, in the future, we writers only need to sit in front of the computer, type with the keyboard, and after they are done, they will be saved on the floppy disk of the computer or other storage tools."

Zhang Shaojie said happily: "Yes, this is the market, this software is very promising, it must be registered as a patent!" In the future, it will also be necessary to write Chinese input method software, so that writers, reporters, editors, and office staff of many companies can use computer keyboards instead of paper to achieve paperless office and paperless writing! ”

Huang Tingjun was also deeply surprised, and said, "Let me see!" ”

"Computer manuscript paper" is a program written by Shaohuai, a beginner who has just learned the knowledge he has just learned. It's just a few hundred lines of code.

However, it already has several functions of entering text, storing text, typesetting, and counting the number of words. Although it doesn't look pretty, the interface is very simple and easy to use.

After Shaohuai's brief introduction, Huang Tingjun took out a floppy disk of "Cangjie Input Method" and entered a line of Chinese characters in the "Computer Manuscript" software vendor.

After that, Huang Tingjun saved the document according to the prompts Shaohuai said.

When I open the previous document again, I will find that the saved content is the same as the content I entered earlier.

Huang Tingjun spoke highly of it and said: "I think that this set of 'computer manuscript paper' software, although it is a little simple, the interface is not very friendly. However, it is completely possible to register as a patent, and after that, find some excellent programmers, rewrite the code, improve the functions of the software, and sell this set of software in the United States and other regions where computers are more widely popular! ”

Shaohuai was surprised and said, "Really? Can my rookie program also be sold on the market? ”
