|
Describe Machine languages 学び始める
|
|
[1] hardware implemented languages. [2] The set of the instructions of a processor. [3] Machine code is usually written in hexdecimal numbers.
|
|
|
Describe Assembly languages 学び始める
|
|
[1] machine codes are wrapped with alphanumeric symbols so that the instructions are more readable. [2] They also have labeled storage locations, jump targets and subroutine starting addresses.
|
|
|
Describe High-level languages 学び始める
|
|
[1] Machine-independent, similar to natural language.[2] Are usually characterised with variables, types, subroutines, functions, constants[3] complex expressions[4] control structures,(conditionals, switches, loops)[5] composite types (arrays, structs)
|
|
|
What does machine independant mean? 学び始める
|
|
independent of the machine instructions of any particular processors)
|
|
|
Describe System programming languages 学び始める
|
|
[1] deal with: memory and process management, I/O operations, device drivers, operating systems.
|
|
|
Describe Scripting languages 学び始める
|
|
[1] used to write programs in system administration [2] analyse / transform large amounts of regular text info [3] act as“glue”between different apps [4] make simple GUI to control an existing app [5] interpreted not compiled [6] Good string processing
|
|
|
Describe Domain-specific languages 学び始める
|
|
unlike general purpose languages, they are used in highly special-purpose areas only, e.g., PostScript - a language for creating vector graphics for the electronic publishing (Adobe).
|
|
|
What are the major Categories by Paradigms 学び始める
|
|
Procedural, Functional, Logic
|
|
|
Describe Procedural Paradigm 学び始める
|
|
[1] A program is built from one or more procedures (subroutines or functions) [2] Central features are variables, assignment statements, and iteration [3] Include languages that support object-oriented programming [4] Include scripting languages
|
|
|
Give some examples of Procedural languages 学び始める
|
|
C, Java, Perl, JavaScript, Visual BASIC. NET, C++,...
|
|
|
Describe Functional Paradigm 学び始める
|
|
Main means of making computations is by applying functions to given parameters
|
|
|
Give examples of some Functional languages 学び始める
|
|
Haskell, LISP, Scheme, ML (MetaLanguage), F#, etc
|
|
|
|
学び始める
|
|
Rule-based (rules are specified in no particular order)
|
|
|

|
|
|
|
|
What are the categories when organiseng languages by How Tasks are Specified 学び始める
|
|
Imperative languages or Declarative languages
|
|
|
Describe imperative languages 学び始める
|
|
[1] computing tasks are defined as sequences of commands (statements) for the computer to perform. [2] a program in such language tells computer what to do step-by-step (to make the computer change from one state to the next).
|
|
|
Give example of Imperative langauage 学び始める
|
|
|
|
|
Describe Declarative languages 学び始める
|
|
[1] programs describe their desired results without explicitly listing commands or steps that must be performed.
|
|
|

|
|
functional and logical programming languages belong to this category.
