How, when and by whom were programming languages ​​developed?

There are programs to program programs, but who developed the programming languages ​​and how? I don't think C+ or Java just popped up on the Commodore desktop.

C++ was developed by Bjarne Stroustrup in the 1980s. Stroustrup extended the programming language C with concepts of object-oriented programming, which he knew from the language Simula. C++ is designed to combine the performance of C with the advantages of object-oriented programming.

The Java programming language was developed at the end of the 1990s by a team (later Oracle). The aim was to create a platform-independent language that is able to run on different systems. Java is based on the syntax of C++.
In general, programming languages have always been iterative, with each a few new functions that are desired by the developer community.

Development takes place approximately in this way

  1. Objective & requirements: Depending on the application, programming languages are programmed accordingly (simple (kotlin), computer games (c++), etc)
  2. Design: on the basis of which the design of the speech is determined (syntax rules, language constructs such as variables functions, semantics, etc)
  3. Implementation: Here a compiler/interpreter is written so that the source code is written in a language (machine code) which the computer can also understand and process.
  4. Testing: Unit tests, integration tests and performance tests are written and the programming language is sufficiently tested so that no embarrassments arise after the release
  5. Documentation: The docu is important so that beginners can also recognize themselves and strike. Usually the syntax, semantics and best-practices are written in.
  6. Maintenance: Unfortunately, you also need to update programming languages as much as any other program. Security leaks, which must be fixed, and developers naturally also want more and more functions to potentially facilitate programming

A classic bootstrap process. I don’t have a Bock to enter the machine code in binary, so I write a program that processes hex values.

Then it is too annoying to read the opcodes in the ISA Doc, so I program a small program that reads Mnemonics and images them on the opcodes – an assembler.

Now I can rewrite the assembler in Assembler and expand it in the skills, because I no longer have to constantly check everything that goes faster and is less cumbersome.

Now I think that I would like to formulate problems algorithmically without using permanent assemblers, but so that it is easier for me. I specify the language and write an interpreter/compiler/transpiler in Assembler. Now I can go and rewrite the compiler/transpiler in the language, it goes faster and easier and expand it immediately to new functionalities.

That’s how it goes on.

C was far before.

The first programming language is assembler, some say. Grace Murray Hopper came to the idea. Previously, programs were pure sequences of numbers for execution.

Plankalkül was the first algorithmic language, says the inventor of algol

For almost all known languages, historical information can be found on Wikipedia, up to the developers and their intention. No one’s gonna put this together and pick it up. But no one keeps you from reading this for himself.

The programming languages have been programmed: “Assembler”.! It’s been since 1948!
