Their are a lot of programming languages to make different types of projects or programs all the programming languages have their own different purposes.
C++ :-
C++ is widely used to make Operating systems, system tools, games, browsers and for many more, C++ is commonly used for graphics-heavy software, C++ is a very popular programming language for performance-critical applications that rely on speed or fast execution and efficient memory management.
Python :-
Python is the most easiest programming language in all languages, it has slow execution speed. The use of python is very popular for making Artificial Intelligence ( AI ), Machine Learning ( ML ), Web development, Game development, Data Science and Data Visualization, Desktop GUI, Web Scraping Applications, Business Applications, Audio and Video Applications.
You can choose python for many purposes depends on you.
Advantages: It is easy to read, write and to learn.
Interpreted language
Improved Productivity
In future python will be a very useful programming language because it also deals with AI and ML.
Java :-
Uses:
Mobile applications (specially Android apps)
Desktop applications
Web applications
Web servers and application servers
Games
Database connection
And much more
It is one of the most widely used programming languages, Java is used as the server-side language for most back-end development.
C# :-
Use:
C# is widely used for developing desktop applications, web applications and web services. It is used in creating applications of Microsoft at a large scale. C# is also used in game development in Unity.
Advantages:
Object-Oriented Language
Automatic Garbage Collection
Cross Platform
Backward Compatibility
Better Integrity and Interoperability
Q) So the question is which programming language should we choose ?
Ans) PYTHON is recommended language if you are new to programming and want to enjoy programming by making your own good projects. Rather than having to jump into strict syntax rules, Python reads like English and is simple to understand for someone who's new to programming.
