Inger is an educational programming language developed by Alex van Oostenrijk, Frank Benders, Dennis Meffert, Jan-Willem Haaring and Thijs Janssen at the Hogeschool van Arnhem en Nijmegen in the Netherlands, released in 2003. It was created to accompany the book "Compiler Construction - A Practical Approach." which discusses the development of a compiler from the ground up. Inger is a simple imperative, strongly typed language, much like C. It has C-interoperability (it can call C-functions, provided that one provides a header file that describes the C-function). Inger attempts to improve readability over the C language syntax by requiring braces for all block statements. ==Sample code== This code outputs "Hello, world!":
