Features

CH supports the 1999 ISO C Standard (C99) and C++ classes. It is a superset of C with C++ classes. Several major features of C99 are supported, such as complex numbers, variable length arrays (VLAs), IEEE 754 floating-point arithmetic, and generic mathematical functions. The specification for wide characters in Addendum 1 for C90 is also supported. C++ features available in CH include: * Member functions * Mixed code and declaration * The '' this'' -> pointer * Reference type and pass-by-reference * Function-style type conversion * Classes * Private/public data and functions in classes. Ch is compatible with C++ in that by default, members of a class definition are assumed to be private until a 'public' declaration is given * Static member of class/struct/union * Const member functions * The new and delete operators * Constructors and destructors * Polymorphic functions * The

As a C/C++ interpreter, CH can be used as a scripting engine and extension language for applications. Pointers to arrays or variables can be passed and shared in both C-compiled and CH scripting contexts. One example of an embedded CH scripting application is Mobile-C, which has been used for collaborative visualization of distributed mesh model. CH has a built-in string type (string_t) for automatic memory allocation and de-allocation. It supports shell aliases, history, and piping. CH has built-in 2D/3D graphical plotting features and computational
