2 .The Languages • Ada (GNAT) • Haskell (GHC) • C (GNU) • Java • C++ (GNU) • Lua • C# (Mono) • Pascal • Fortran (GNU) • Python 2 • Go • Python 3 • Scala 

3 . A is for Ada Ada is a structured, statically typed, imperative, high-level computer programming language, extended from Pascal and other languages. It has language support for design-by-contract, strong typing, explicit concurrency, offering tasks, synchronous message passing, protected objects, and non-determinism. 

4 . C is for C C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion. C provides constructs that map efficiently to typical machine instructions. 

5 . C is for C++ C++ is a middle-level programming language developed by Bjarne Stroustrup starting in 1979 at Bell Labs. C++ runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX. 

6 . C is for C# C# is a general-purpose, object-oriented programming language. It was developed by Microsoft within its .NET initiative. 

7 . F is for Fortran Fortran is an imperative programming language suited for numeric and scientific computation that has gone through many decades of revisions. 

8 . F is for F# F# is developed by the F# Software Foundation, Microsoft and open contributors. An open source, cross-platform compiler for F# is available. F# is also a fully supported language in Visual Studio and Xamarin Studio. Other tools supporting F# development include Mono. F# originated as .NET implementation of a core of the OCaml programming language. 

9 . G is for Go Go is an open source programming language created at Google in 2007. It is a compiled, statically typed language in the tradition of Algol and C, with garbage collection, memory safety features and CSP-style concurrent programming features added. 

10 . H is for Haskell Haskell is a standardized, general-purpose purely functional programming language, with non-strict semantics and strong static typing. It is named after logician Haskell Curry. 

11 . J is for Java Java is an imperative, object-oriented programming language designed as an improvement over C++. 

12 . L is for Lua Lua (LOO-ə, from Portuguese: meaning moon) is a lightweight multi- paradigm programming language designed primarily for embedded systems and clients. 

13 . O is for OCaml OCaml, originally known as Objective Caml, is the main implementation of the Caml programming language. OCaml is a free open source project managed and principally maintained by INRIA. Many newer languages have drawn elements from OCaml, most notably F# and Scala. 

14 . P is for Pascal Pascal is a historically influential imperative and procedural programming language, designed in 1968–69 and published in 1970 by Niklaus Wirth as a small and efficient language intended to encourage good programming practices using structured programming and data structuring. 

15 . P is for Python Python is a widely used high-level, general-purpose, interpreted, dynamic programming language. Its design philosophy emphasizes code readability, and its syntax allows programmers to express concepts in fewer lines of code than would be possible in other. 

16 . R is for Rust Rust is a general-purpose, multi-paradigm, compiled programming language sponsored by Mozilla Research. It is designed to be a "safe, concurrent, practical language", supporting pure-functional, imperative- procedural, and object-oriented styles. 

17 . S is for Scala Scala is object-oriented, and uses a curly-brace syntax reminiscent of the C programming language. Scala has many features of functional programming languages like Scheme, Standard ML and Haskell, including currying, type inference, immutability, lazy evaluation, and pattern matching. It also has an advanced type system supporting algebraic data types, covariance and contravariance, higher-order types, and anonymous types.
