Programming languages ?

 A programming language: is a type of written language that tells computers what to do in order to work. Programming languages are used to make all the computer programs and computer software. A programming language is like a set of instructions that the computer follows to do something.





A programmer writes source code text in the programming language to create programs. Usually the programming language uses real words for some of the commands, so that the language is easier for a human to read. Many programming languages use punctuation just like a normal language. Many programs now are "compiled". This means that the computer translates the source code into another language (such as assembly language or machine language), which is much faster and easier for the computer to read, but much harder for a person to read.



Computer programs must be written very carefully. If the programmer makes mistakes, or the program tries to do something the programmer did not design it to do, the program might then "crash" or stop working. When a program has a problem because of how the code was written, this is called a "bug 👹 ". A very small mistake can cause a very big problem. For example, forgetting a comma or typing a plus sign instead of a minus sign can cause a bad bug.


History

The history of programming languages ​​goes back more than 125 years before the emergence of the computer itself, Programming languages ​​first appeared in some industrial uses, It has been adopted to control the production of textiles by designing holes in a specific way on different types of cards, so that these cards are changed to produce different types of textiles.

The real appearance of the first programming language is considered in the year 1956 , Where a team from IBM developed a programming language known as (FORTRAN), then followed in 1958  the second oldest programming language known as (LISP) appeared, and different programming languages ​​continued to appear throughout the twentieth century when some programming languages ​​appeared that are still used. So far as a programming language (Basic) that was invented in the year 1964.

The seventies witnessed the emergence of a new concept of programming languages, which is the concept of object-oriented programming. As a Pascal language that was developed in 1971 by Niklaus Wirth, and programming language (C) that appeared in 1972 , while the database programming language (SQL) that was developed by Edgar Code appeared in 1974 , and this language is still one of the languages The main and important until the present time, as the programming language (C ++) appeared in the year 1979.

The spread of the Internet led to the development of many programming languages, Tim Berners-Lee developed the HTML programming language in the year 1990 , followed by the next year the emergence of two of the most important programming languages ​​in the world, namely the Python programming language and the Visual Basic programming language. (Visual Basic), and 1995 was the year of the emergence of the Java programming language that was introduced by programmers at Sun Microsystems,  and at the present time there are tens of thousands of different programming languages ​​as well as the continuous development of new languages. The designers believe that it will contribute to solving any problem that exists in a person's life.



In the following articles I will talk about different languages ​​like (Java, JavaScript, Python ...) and we will also see some of their uses.

Beliefs

 We Live In A System Of Beliefs The accompanying article about convictions is only a declaration of my contemplations. It is absolutely not complete. As I would see it, we carry on with our life based on convictions. We, in a real sense, live in a colossal conviction framework. So flawlessly coordinated (into our reality) are a few convictions that a great many people expect that they are regular and acknowledge them without addressing. The actual demonstration of perusing this article is conviction based, in light of the fact that the very build that is shaped in your mind presently is calculated and of the reasoning psyche. Maybe, what truly is doesn't simply exist as ideas, yet in addition exists in the NOW as experience. Albeit one can portray or conceptualize a reality, the conceptualization is itself an idea. Convictions can be exceptionally incredible, particularly when most of the populace gets tied up with it. At some point a specific conviction when gotten rolling, ...

Modules et Packages dans Python

  Modules et Packages : Un module est tout simplement est un ensemble des fonctions qui existes dans un fichier .py è c’est l’extension d’un fichier python. Et si on regroupe plusieurs modules dans le même dossier, on appelle ça un Package , ce dossier doit contenir un fichier important s’appelle __init__.py . Egalement ce fichier -__init__.py- indique à python qu’il s’agit d’un package. Ce fichier peut être vide, seule sa présence est importante. Création d’un module : Simplement, ou crée un fichier python qui s’appelle par exemple funcs , et je vais ajouter quelque fonctions simple à ce fichier. C’est le temps d’utiliser ces fonctions dans notre fichier principal ( Comment faire ça ) : Nous devons importer notre module qui s’appelle funcs en utilisant import , après on appelle notre fonction. Création d’un package : Pour créer un package, on commence par la création d’un dossier dans le même dossier que notre programme, ce dossier porte le nom de notre p...

JavaScript

JavaScript Introduction : Avons-nous même besoin d'introduire JavaScript ? C’est l’un des langages de programmation les plus populaires au monde ! Avez-vous déjà visité un site Web qui vous a fait penser… "Hé, ce site Web est vraiment cool et interactif» ? Eh bien, JavaScript était probablement en train de le faire. C'est donc juste utile pour les sites Web, n'est-ce pas ? Faux ! Traitez les données, les applications mobiles et de bureau, les jeux, le monde est votre huître avec JavaScript.                  Variables : Les variables sont des conteneurs pour stocker les valeurs de données. La valeur d'une variable peut changer tout au long du programme. Déclarer une variable est aussi simple que d'utiliser le mot-clé var. Ce qui ressemblerait à ceci :         Dans cet exemple, nous avons attribué une valeur de 10 à la variable x. Nous avons utilisé le mot ass...
