Programming Languages
Introduction
A programming language is a set of rules and guidelines that tells you how to write programs. It can be used by all kinds of people, from the most experienced programmers who build large software systems to those who want to write small programs for personal use.
What is a programming language?
A programming language is a set of rules for instructing a computer to perform specific tasks. It's a way of programming computers, and it consists of keywords, data types (see below), and syntax rules.
Programming languages can be used in any application that involves turning human-readable text into machine-executable code—but they're especially useful for writing code for websites or mobile apps.Most of the programming languages are text-based in formal languages. But they may also be graphical. They are a kind of computer language.
Here Are the main 5 Programming Languages:
1.Python
Python is a general-purpose programming language that's often used in web development, data science and machine learning. It's also used for scientific computing and numerical analysis.
Python was developed by Guido Van Rossum in the early 1990s for use at the Python Software Foundation (PSF). The first version was released in 1991 as an extension of BCPL, which had been developed at a computer laboratory called Bell Labs.
2.Java
Java is a programming language that was created by James Gosling at Sun Microsystems. It's used to create applications and mobile apps, web apps, desktop apps and more.
Java is an object-oriented programming language that allows you to write code in a more structured way than other languages like C++ or C#. For example:
You can declare variables like this:
int i = 10; // declares variable i with initial value 10 (or 0 if you want it initialized)
You can use methods to do things like add two numbers together:
float f1 = 2 + 3; // declares float f1 with value 4
3.JavaScript
JavaScript is a scripting language that can be used on the client side or the server side. JavaScript is most commonly used to add interactivity to web pages, but it's also helpful in building client-side applications and websites. If you want to build websites, learning JavaScript will give you the necessary skills needed for this type of programming job.
JavaScript was originally developed by Brendan Eich at Netscape in 1995 as part of their Navigator browser plug-in for Internet Explorer 3 (IE3). It was released as free software in 1996 under an open source license called "GNU General Public License (GPL)." Today, there are many other competing implementations of JavaScript such as NodeJS which has become popular among developers due its ability to run servers alongside desktop environments like MacOS X; Linux distributions like Ubuntu; as well as mobile operating systems such as Android and iOS devices!
4.C++
C++ is a general-purpose programming language with a long history. It was developed by Bjarne Stroustrup in 1985 and released as an open standard on December 9th, 1998.
It's used for writing system software, applications, and games
It's compiled: you don't need to compile every time you want to use it because the compiler does it for you
C++ has been around since 1985 (although some people think that this doesn't make it old enough)
5.SQL(Structured Query Language)
SQL is a programming language used to manage databases. It is the most common database management system in use today. SQL is an acronym for Structured Query Language and it's also known as "SQL Server" because it was originally developed by Microsoft Corporation.
SQL has been around since 1970 when IBM created its first version of Structured Query Language (SQL). In 1976, Oracle Corporation released its first version of Oracle Database Management System (DBMS), which later became known as Oracle 10g and 11g databases before moving onto 12c in 2014 with some minor changes such as adding new features such as Docker support
These are the top programming languages. Many are object-oriented
If you want to learn a programming language, you should start with one of these.
The language that interests you the most.
The language that is easy for beginners to learn.
A widely used programming language (so it's easier for employers and recruiters).
If you are interested in learning Python or Java, then go ahead and do so! But if your goal is finding a job as a software developer, then it might be better not spend too much time learning these languages until after graduation.
Conclusion
If you want to learn a programming language, you should start with one of these. They are the languages that have been around for a long time and have proven themselves in many different industries. The languages listed above are all very different from each other but they all have their own strengths and weaknesses as well as limitations. It's important not to make too many comparisons when learning because each one is designed differently than others so there will always be some aspects which aren't applicable for every scenario
