1. Java
Java is an object-oriented programming language developed by Sun Microsystems in 1995. In less than 20 years, Java has become among the most popular programming languages in the world. Java is platform independent, which means that programs made for Windows can be run on Mac OS and Linux, and vice versa. This feature makes java more powerful than other Programming languages. Java is the go-to language for most enterprise applications.Most senior developer positions require a working knowledge of Java and/or C.
2. C Language
C is one of the oldest programming languages used today and was originally developed in 1972 by Dennis Ritchie at Bell Labs. C is the “father” of many programming languages, including C#, C++, Java, Perl and JavaScript.
C is powerful easily available and stable on virtually all platforms. Many popular languages like PHP and Python are written in C. This is the reason why C is one of the first languages taught to students, So that it can help students for learning other languages.
3. C++
C++ was originally created in 1983 to address the shortcomings of the C language. C++ is an intermediate-level language with object-oriented programming features. It powers some of the most popular desktop applications in the world, including the Adobe software (Illustrator, Adobe Photoshop etc.), Mozilla Firefox, Google Chrome, and Winamp.
4. C#
C# (pronounced “C-Sharp”) was developed by Microsoft in 2000 as a fundamental part of its .NET framework. C-Sharp is an object-oriented and multi- paradigm programming language that combines the best of C and C++ and Learning C# is a must for any programmer who wants to develop for Microsoft platforms.
5. Objective-C
Objective-C was developed in 1983 by Tom Love and Brad Cox at Apple to address the objected-oriented deficiencies of C language and Objective C is the primary language used in Apple OS X and iOS operating systems. The rush in popularity of Macs and Apple “i’” devices (like iPad and iPhone) has created a huge demand for Objective-C programmers and A working knowledge of Objective-C will help you develop application for iOS, which make a start for thousands of jobs in startups as well as big tech companies. As an Objective-C programmer, you can also create apps for iOS on your own and freelance.
6. PHP
PHP (Processor Hypertext) is a server-side scripting language that powers more than 244m websites online, including the famous publishing platforms Drupal, WordPress, Joomla. Created in 1995, PHP is one of the growing languages on this list.
PHP is relatively easy to learn and can be readily embedded within HTML pages which has made it the go-to general purpose programming language. The big demand for web application developers has led to a huge overflow in PHP jobs. Bone up PHP is often the first step to becoming a full-fledged web developer.
7. Python
Python was created in 1991 by Guido van Rossum and it is a high-level programming language makes much of readability and simplicity and is a great language for beginners to start their programming trip. Python has enjoyed comeback in popularity in the last few years and now powers some of the most popular websites in the world, like Pinterest.com, Instagram.com and Rdio.com through its associated web framework, Django. Even Google has invested especially heavily in Python development in the last decade, which has further added to the language’s popularity (in fact, Python founder van Rossum was a Google employee from 2005 to 2012).
8. Ruby
Ruby was developed in 1995 by Yukihiro Matsumoto by combining aspect from Perl, Lisp and Eiffel. It is an object-oriented and dynamic language that emphasizes automation and simplicity. Ruby powers the Ruby on Rails framework, which is used on popular websites like Scribd, Github, Groupon, Yammer and Shopify. Many students new to programming also find Ruby comparatively easy to learn because of its simple syntax and English-like readability.

Conclusion

What programming language you choose to learn should be determined as much by personal tastes and demand, as by job availability. The job market for programmers is sometimes stable. Languages that are in trendy today might not be so in the next few years. Objective-C, for instance, was widely ignored throughout the 1990s, but increase in popularity with the resurgence of Apple as a tech powerhouse in the 2000s. As a programmer you will be familiar to be proficient in at least one “workhorse” language just like Java or C, but you can always choose to train in any other language that excites you intellectually.
