History of programming language
Assembly (1940s) is a low-level programming language (hardware-related) that was more commonly used for computers at that time,
IBM Machine Systems developed the first commercialized high-level programming language (human communication) called Fortran (1957). Fortran is a programming language built with assembly code. Later, Basic (1964) , Pascal (1970) , Which created one to one in assembly language
Dennis Ritchie (Computer Science) developed a language for building an operating system called Unix (1969-1973), which consisted of several programming languages called an assembly, algol (1958), FORTRAN, B (1969) all written, or ended in assembly language. All computer engineers turned to this language because all operating systems were commercialized in this language and it was easier than other programming languages.
Programming Languages for operating systems
C++ is a language that is directly related to the C language, in which the graphic language can also be written. This language was created in Bell Labs. Basic operating systems used both C (1972) and C++ (1985) to build graphical operating systems such as Windows.
Almost all graphical operating systems are made of C++ and the kernel is written in C, such as android (based on FreeBSD and Linux), IOS (based on FreeBSD), macOS (based on FreeBSD), Debian (based on Linux), windows (based on DOS / OS with a few changes).
So what is the purpose of PLP? And what is he supposed to do?
