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.
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.
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.
There are two programming languages classified as:-
high level language and low level languang
The major advantages of fifth generation programming languages are that these languages are improved from fourth generation languages. It is also important to note that classification of programming languages in generations beyond the second generation is complete nonsense and nothing but a marketing hype; programming languages don't evolve in a linear succession, or one in the shape of a balanced tree, where each generation has common attributes and improvements over the previous generation.
Statically typed languages.

Procedural programming is a computer programming technique in which the program is divided into modules like function or subroutine or procedure or subprograms, where as ... "Modular Programming" is the act of designing and writing programs as interactions among functions that each perform a single well-defined function, and which have minimal side-effect interaction between them. Put differently, the content of each function is cohesive, and there is low coupling between functions as happens in procedural programming.

Multiprocessing means the computer can do multiple processes parallel of each other (at the same time) with no performance degradation. Multiprogramming is an application that can be used to interface with different programming languages (java, C++, etc)

In Structured Programming also known as Modular Programming Each Method(function) is structured itself. Such logical structure make programming more efficient and easy to understand. it employs Top-Down design model.

The Language of the Day feature showcases different programming languages each day, highlighting their key features and use cases. It aims to provide insights into various programming languages and promote learning and understanding in the tech community.
I am made up of multiple programming languages, including Python, Java, and C++. Each language serves a specific purpose and contributes to the overall functionality of the assistant.
AnswerProcedural languages are used in the traditional programming that is based on algorithms or a logical step-by-step process for solving a problem.A procedural programming language provides a programmer a means to define precisely each step in the performance of a task Non-procedural programming languages allow users and professional programmers to specify the results they want without specifying how to solve the problem. examples are FORTRAN,C++,COBOL,ALGOL etcOR we can put it this way:Procedural language determines WHAT & HOW a process should be done, Non-procedural language is concerned with the WHAT not the HOW. Non-proc languages are those languages where you specify what conditions the answer should satisfy, but not how to obtain it.
Without them you wouldn't be able to program :P. Besides that though, each programming language has a different level of abstraction, meaning how closely they resemble machine code. Low-level programming languages closely resemble machine code while high-level languages more closely resemble actual words and are more intelligible. Low-level languages are generally considered harder to learn than high-level languages and take more instructions to do something than a program made in a high-level language made to do the same task.
The role of an interpreter in programming is to interpret a high-level language into machine code. The interpreter reads each line of the program as it is being run, and converts it into machine code that the computer understands. Examples of interpreted languages are Python, Ruby and Perl. This differs from lower-level programming languages like C, where the code is compiled into machine code before it is run.
