It is also very readable, easy, and above all because of the productivity issue.

C Sharp is used in web application development, Windows applications, and mobile applications for both iOS and Android operating systems, game development, and server-side programming.

C / C ++:

The oldest language on the list but one of the most used in programming

C ++ has many advantages, among them the efficiency of the code being among the most used programming languages.

Bjarne Stroustrup designed the C ++ programming language in 1979; it is an extension of C with object manipulation and is considered a hybrid language. For years he has had a large community supporting his career in software development.

One of the great advantages of this language is the efficiency of the code, and it is popular for creating system and application software. It is used in software infrastructure, desktop applications, and servers, etc. Thanks to all its characteristics, it is never missing among the lists of the best programming languages ​​most used worldwide for many years.


It is a language to develop web with more usability and used by developers

PHP is an open-source programming language and widely used for web development

The Danish-Canadian developer Rasmus Lerdorf created the PHP programming language in 1994, an acronym for hypertext Preprocessor, and is an open-source programming language that can be embedded in HTML; it is widely used for web development.

PHP is popular since multiple web pages and portals are developed with this programming language: Wikipedia, Sourceforge, Facebook, and Sourceforge. Among its main advantages is that it has a very low learning curve, the environments to be developed are easy and quick to configure, it is easy to access and integrate with databases, it is also a multiplatform language and has a very large community that supports it. Endorses, as a consequence of that great community, it is a language with the greatest use in the world.


Of the best environments and programming languages ​​oriented to the most used statistical analysis

R is an environment and programming language with a perspective to statistical analysis.

Among the most used R is an environment and programming language with a perspective to statistical analysis. This language arose from a free software reimplementation of the S language and is used in scientific research, machine learning, and data mining.

Among its main features are effective handling and storage of data, graphical utilities to visualize the data; it is well developed, including conditional jumps, loops, recursive functions, and utilities for data input and output.


one of the programming languages ​​with decades and currently one of the most used

Objective-C is the primary programming language on iOS, Mac OS X, GNUstep, including this Swift list.

Brad Cox developed the Objective-C programming language in 1980. Today it is used as the main programming language in iOS, Mac OS, GNUstep, including Swift on this list. This programming language contains supersets C.
