What are the classification of programming languages differentiate each?

Answer 1

Imperative languages, also called algorithmic languages, are probably

the most prevalent among the programming language paradigms today.

Their programs are constructed as algorithms or as sequences of

executable instructions.

These languages are greatly concerned with variables and include

commands for sequentially allocating memory space or CPU locations to

these variables and for correspondingly changing their values through

assignment statements or procedure execution.

The three main categories of imperative languages are as follows:

· Block-Structured or Procedural Languages - These languages are

process or "how" oriented. Their basic unit of modularization is the

function or the procedure. A modular unit is comprised of a set of

data declarations and statements. Examples: ALGOL, Pascal,

Modula-2, Ada, and C.

· Object-Oriented Languages - These languages are data or "what"

centered and implement the principle of program decomposition,

data abstraction, and information hiding. They are based on the

fundamental concept of objects. Examples: Smalltalk, C++, Java,

and Visual Basic.

· Distributed Programming Languages - These languages support

more than one processor working either simultaneously or

alternately with other processors in order to complete a task or to

solve a problem.

Declarative languages are those based on relations or functions. Theyinclude facilities for writing declarations or truths. Compared to

imperative languages, they are considered to have higher level than the

former since they work around concepts and not with a machine's

storage locations.

The three main categories of declarative languages are as follows:

· Functional or Applicative Languages - These languages consider

the function as their major organizing principle. Examples: LISP,

APL, and ML.

· Logic Programming - These languages describe computing

problems in the form of predicate logic statements. PROLOG is the

first thing that comes to mind when talking about logic programming.

· Languages for Databases - Languages that support databases

include facilities for accessing/selecting data from database entities,

and describing relationships between data entities. Example: SQL.

Answer 2

Programming languages are divided into two basic groups.

High level and low level.

Low level languages (Machine languages) process one instruction for one command. LDA in MC6502Be is a single 8 bit instruction for instance which only loads the accumulator in the processor.

High level languages process multiple instructions for one command (Print is an 8 kilobyte program which handles formatting, text et.c).

High level languages can be further classified by design such as OOPL or object orientated programming languages where the instructions are grouped according to specific functionality in a modular way.

Answer 3

There are two main ways to classify a programming language: by level of abstraction or by paradigm.

There are two levels of abstraction: low-level and high-level. Low-level languages more closely represent the native machine code architecture of the computer, like assembly language. C is even considered a low-level language nowadays because it provides direct access to low memory. High-level languages are more "human" in appearance, meaning they look more like English.

There are multiple paradigms with which to classify programming languages. For instance, there are object-oriented (OO) languages, procedural, functional, declarative, and multi-paradigm languages.
