All about Programming.
what is a programming language?
The programming language is a formal language comprising a set of instructions that produce various kinds of outputs. and its uses to develop scripts, software programs and etc
The main types of programming languages are :
Procedural programming language: a procedure-oriented programming language that follows a step-by-step approach to break down a task into a collection of variables and routines through a sequence of instructions each step is carried out in order in a systematic manner so that a computer can understand what to do.
Object-oriented programming language: oop is a programming language that uses classes and objects to create models based on the real-world environment. The pillars of Oop are Encapsulation, inheritance, polymorphism, abstraction.
Functional programming language: Functions are self-contained modules of code that accomplish a specific task. Functions usually “take in” data, process it, and “return” a result. Once a function is written, it can be used over and over and over again. Functions can be “called” from the inside of other functions.
Scripting: A scripting or script language is a programming language for a special run-time environment that automates the execution of tasks; the tasks could alternatively be executed one-by-one by a human operator. Scripting languages are often interpreted, rather than compiled.
Logic programming language: Logic programming is a programming paradigm that is largely based on formal logic. Any program written in a logic programming language is a set of sentences in logical form, expressing facts and rules about some problem domain.
How many programming languages are there?
According to Wikipedia, there are 700 programming languages. Although many languages share similarities, each has its own syntax. Once a programmer learns the language's rules, syntax, and structure, they write the source code in a text editor or IDE. Then, the programmer often compiles the code into machine language that can be understood by the computer. Scripting languages, which do not require a compiler, use an interpreter to execute the script.
The best programming languages to learn in 2021:
Javascript, Python, Go, Scala, c#, Ruby, Php, R, swift.
Ada Lovelace is the first computer programmer.
The First Programming language is (FORTRAN).
In 1957, the first of the major languages appeared in the form of FORTRAN. Its name stands for FORmula TRANslating system. The language was designed at IBM for scientific computing. The components were very simple and provided the programmer with low-level access to the computer's innards.
