What is the classification of Programming Languages

Classification of programming languages: Programming languages ​​can be classified according to various criteria. The most important grouping is by: abstraction level, purpose, execution method, and programming paradigm.

Classification of programming languages ​​according to their Level of Abstraction: 

  1. Low Level Languages ​​are machine code languages, they are a set of instructions in binary code that the computer is capable of executing directly, specific to each type of processor or CPU. Examples: Machine language and assembly languages.
  2. High Level Languages ​​more similar to natural language, close to the problem, we forget the internal structure of the computer Examples: C, Basic, Java.

Interesting: Higher level and lower level languages

Classification of programming languages ​​according to their Purpose:

  1. General Purpose Languages ​​allow the implementation of practically any algorithm, the level of abstraction is more uniform, it provides reasonable performance. Eg Pascal, C, C++, Java, Delphi, Lisp, Scheme.
  2. Specific Purpose Languages ​​generally have a very restricted set of features and a high level of abstraction to accomplish specific tasks such as word processing, graphics, audio, video, and engineering. Examples: Snobol, SQL, Matlab.

Classification of programming languages ​​according to their Execution method:

  1. Compiled languages ​​translate the source code of the program to machine code or object code. Examples: C, Pascal
  2. Interpreted languages ​​execute the instructions of a program line by line. They require the source code to run the program. Examples: Perl, Lisp.

Classification of programming languages ​​according to their Programming Paradigm.

  1. Imperative languages ​​are abstractions of some sequence of instructions that specify in detail the order of execution of the program. Examples: Fortran, Algol, Ada, Pascal, C, C++
  2. Declarative languages  ​​express what the program is to accomplish without prescribing how to do it, in terms of sequences of actions to be taken. Examples: SQL, HTML, RPG
  3. Functional languages ​​consist of a set of pre-defined functions. Examples: Lisp, Scheme, Common Lisp, ML, CAML
  4. Logic languages ​​express tasks using formal mathematical logic. Example: Prolog.
  5. Object Oriented Languages ​​create a system of classes and objects following the schema of the real world to define the objects, actions and way of communicating between objects. Examples: C++, Java.
