eC (Ecere C) is an object-oriented programming language, defined as a super-set of the C language. eC was initially developed as part of the Ecere Cross-platform Software Development Kit project. The goals of the language are to provide object-oriented constructs, reflection, properties and dynamic modules on top of the C language while maintaining C compatibility and optimal native performance.eC currently relies on GCC or Clang to perform the final steps of compilation, using C as an intermediate language.

Example from Riju:
class Main : Application { void Main() { PrintLn("Hello, world!"); } }
Example from hello-world:
class HelloWorldApp : Application { void Main() { PrintLn("Hello World"); } }
