Types of Computer Languages

Programming/computer languages refers to the act of describing processes and procedures by developing a list of instructions and commands for understanding of a computer.

The type of objects that these instructions use are numbers, words, voice, images, etc . The goal of making programing language is to make a computer perform a quick task and get results which would be nearly impossible for a human being to perform in a timely and proper manner. The tasks we instruct a computer to make are usually very fast and can involve millions of calculations in a short period of time.

First programing language — — Fortran

Fortran was basically designed for engineers and scientists in 1957……. it is used to design big projects Like — — cars, bridges, Airplane …etc

The language was introduced by IBM ( International Bussiness machines) and designed by John Backus

John Backus

A simple program in Fortran……

Program to add two numbers — — -

a= 12.0

b=15.0

result = a+b

print *, ‘ The total of two number is — -’, result

output — -

The total of two number is 27.0000000

So……in above para we learn about Fortran language which is basically design for engineers — — -but now we learn about the language which helps to design websites, software, operating systems, etc …..

A language that combines all the powers of assembly language …………“ C ” language.

C language was first designed by Dennis Ritchie in AT&T‟s BELL Laboratory of the USA in 1972….It is a structured programming language that is machine-independent. One can say, C is a base for coding. If you know ‘C,’ you can easily grab the knowledge of the other languages that use the concept of ‘C’

Uses of “ C ” language

UNIX operating systems are written in C and Linux is also in C. Also databases such as Oracle, MySQL, MS SQL Server, and PostgresSQL are written in C. C is the basis of many system kernels. Programming languages, like Python and Perl, use compilers or interpreters that are written in C.

A basic program in “C” language — -

#include<stdio.h>

#include<conio.h>

void main()

{

int number1, number2, sum;

printf (“ENTER TWO INGTEGERS”);

scanf(“%d %d” & number1, number2);

sum= number1+number2;

printf(“%d + %d”, sum”);

}

OUTPUT —

ENTER TWO INTEGERS-

11

12

23

Now we come on languages which are used for design websites — — — -

First one and most important language — — HTML

The full form of HTML is Hyper Text Markup Language , the language was first discovered by Tim- Berners- lee in 1993…..it is used to create a websites. HTML is a series of short codes……Lets see the basic code of HTML — —

<!DOCTYPE html> (Defines the version of HTML)
<html>
<head>(This is a container for metadata and is placed between the html tag and the body tag)
<title>MY FIRST WEBPAGE</title> (It defines the title of webpage)
</head>
<body>( This element contains all the contents of an htmldocument, such as headings, paragraphs, images, hyperlinks etc.)
<p> first paragraph.</p> (They print simple text on the browser.)

</body>
</html>

The second important language used in website designing — — CSS

CSS (cascading style sheet)

CSS has a simple syntax and uses several English keywords to specify the names of various style properties.CSS is designed to enable the separation of presentation and content, including layout colors, and fonts This separation can improve content accessibility provide more flexibility and control in the specification of presentation characteristics, enable multiple web pages to share formatting by specifying the relevant CSS in a separate .css file which reduces complexity and repetition in the structural content as well as enabling the .css file to be cached to improve the page load speed between the pages that share the file and its formatting.

Why is CSS important for HTML ?

CSS (Cascading style sheets) is the language for describing the presentation of Web pages, including layout, colors, background, image, etc.it allows web designers to make our website unique and responsive. CSS was first proposed by Hakon Wium Lie on 10 October 1994. At the time, Lie was working with TIM BERNERS-LEE. In 1995, he worked on the CSS specifications, including CSS1 and CSS2. Håkon Wium Lie attended ostfold University College, West Georgia College, and MIT Media Lab, receiving an MS in Visual Studies in 1991. He has worked for, among others, the W3C, INRIA, CERN, MIT Media Lab, and Norwegian Telecom research in Televerket

Let's talk about Backend languages — — -

The front end majorly deals with the UI part of coding where the web servers communicate with the users and backend development is the coding that happens at the server-side. The front end is visible to the viewers whereas the backend helps internally.

List of some backend languages — -

Ruby was developed back in the mid-1990s in Japan, which may be the reason why it’s often called “an elegant and powerful language”. It is an open-source, object-oriented, dynamic language...

Add two integers in ruby

def sum_double(x, y)

x == y ? (x+y)*2 : x+y

end print sum_double(5, 5),”\n”

print sum_double(4, 5)

Meaning of object-oriented language — -

Object-Oriented Programming is a programming paradigm that runs on the concept of classes. An object-oriented language program is run around a signal object. It is used to structure a software program into simple, reusable pieces of code blueprints which are used to create individual instances of objects. There are many object-oriented programming languages including C++, python, c#, Lingo, java m, Logtalk, etc…..

Let us talk about the backend language SQL— —

SQL stands for Structured Query Language, the work of SQL is to communicate with a database. It is the standard language for relational database management systems. SQL statements are usedto perform tasks such as update data on a database or retrieve data from a database.SQL is the most mainstream language that is used to access databases because it can work with any database. The databases, with which you interface, are programs that enable clients to store and manage information in a logical manner SQL is known as a query language……it is designed by Donald D. Chamberlin and Raymond F. Boyce
