How was the world s first programming software born???

Written directly in machine code, it is estimated that it is n long

In fact, in addition to the C language, there are many other basic languages, but in the current world of programmers, the C language is still a god-like existence, because the C language is the earliest comprehensive programming language, all programs and various operating systems on the market can be realized through the C language, programmers can build programming software in many fields through body language, and then continue to play through these built programming software, and then form the final entity existence, This is the relationship between the upper and lower levels I mentioned above, the C language is the boss of all programming software, as long as you master the C language, you will also master the subsequent development of programming software.

The language is definitely a crucial invention in human history, and without its appearance, our modern technology might not have developed so rapidly.

Take a computer as an example, how is a computer made?

This can be traced back to the original diode, which in turn can be traced back to the very beginning of the Morse code, and the invention of the Morse code is actually not honorable, it is for war!

At the beginning, what we used for password transmission was actually two ciphers, long and short (or dots and lines), that is, the original binary 0 and 1, but the limitation was that it could only be used for written transmission, and it was necessary for an intelligence officer to send the password to friendly forces.

In order to facilitate the transmission of binary ciphers, we invented the diode (pn junction), and the way of controlling the circuit is path 1 and open circuit 0, which greatly improves the efficiency of password transmission and decipherment, and there is also the later telegraph, but this kind of password transmission has great limitations, that is, the content of the password can not be too much, otherwise it is very troublesome to decipher, and it is easy to make mistakes in the case of too long length, resulting in the transmission of wrong information.

So we invented octal, decimal, hexadecimal.

And the base system has been upgraded, and the limitations of a single diode have also come out, that is, the speed of processing data is very slow, and at this time the world war has basically ended, but for the development of science and technology, this technology has not been left behind.

So slowly, the diode gradually became more complex and evolved into our current CPU, in fact, the essence of the CPU is countless diodes (PN junctions). Similarly, many other electrical components in a computer are made from the most basic diodes, including monitors, mice, keyboards, and so on. And their essence is only two:

Path 1 and open circuit 0, which is why the computer only knows the principle of 0 and 1.

Programming software is used for programming, and programming software is created using programming software. The C language is very useful, and all applications are built on top of the basic API, so a rich application layer is born.

When we understand what programming is, we will understand that programming software is nothing more than turning logical relationships into machine language, so programming software is actually made according to the original conversion rules.

The lowest program of programming software is the compiler, and the compiler of the early language is written in assembly**, and most of the other compilers are written in assembly or C.

At first, it was 01, and then programmers packaged 01 into functions, and the packaging from generation to generation is what is now a high-level language.

Written in a programming language.

The earliest was a machine language that could directly input binary code running on a computer.

Then came the assembler, which could convert assembly language into machine language.

Then came the compiler, which could translate C into machine language.

Then, you can write all kinds of software in C.

This problem is easy to explain.,Computer desktop right-click to create a new notepad to write**,Programming software is just a simplification of things.。

Any language is a platform and needs to have rules for mutual licensing in order to communicate and communicate.

Early computer software was written directly in assembly language, and this continued for several years. High-level programming languages were invented when it was discovered that the overhead of writing reusable software for different types of CPUs was significantly higher than writing compilers. Due to the small amount of memory in early computers, many technical difficulties were encountered when implementing compilers.

Around the end of the 50s of the 20th century, machine-agnostic programming languages were first proposed. Subsequently, several experimental compilers were developed. The first compiler was written by Grace Hopper in 1952 for the A-0 language.

It is generally accepted that the first complete compiler was introduced in 1957 by the Fortran team led by IBM's John Barcos. In the 1960s, COBOL became one of the first languages to be compiled under multiple architectures.

High-level languages have become popular in many areas. The architecture of computers is becoming more and more complex due to the increasing number of features supported by new programming languages, which makes compilers more and more complex.

Early compilers were written in assembly language. The first compiler capable of compiling its own source code was made in 1962 by Hart and Levin of the Massachusetts Institute of Technology. From the 70s of the 20th century, it became more and more feasible to implement compilers that could compile their own source programs, although it was more popular to implement compilers in Pascal and C.

To make the first compiler for a language, you either need to write it in another language, or you need to run the compiler with an interpreter like Hart and Levin's LISP compiler.

The first?

The first people were ...... to write binary instructions directly in machine languageLater there was a compilation ......And then there were high-level languages.

Since the birth of the world's first programmable logic controller (PLC) in 1969, programmable control technology has been singing all the way in the field of industrial control and has achieved a wide range of applications. However, in the past 30 years, the rapid development of computer technology, electronic technology, network communication technology and automatic control technology has made engineers far exceed the simple expectations of "sequential logic control" in industrial applications.

The first software, which should be written in machine language, input 0,1, and then there was a low-level programming language, that is, assembly language, and later there was a high-level language, but assembly because of its strong operability of hardware, there are still many people who use it in many places.

Software is a program, and the first software was born with computers in 1946.

No, the initial software was programmed directly with the calculator.

The first software is assembled in assembly language.
