Ch (computer programming)
From Wikipedia, the free encyclopedia
CH /ˌsiːˈeɪtʃ/ is a proprietary cross-platform C and C++ interpreter and scripting language environment. It was originally designed by Harry Cheng as a scripting language for beginners to learn mathematics, computing, numerical analysis (numeric methods), and programming in C/C++. Ch is now developed and marketed by SoftIntegration, Inc., with multiple versions available, including a freely available student edition, and a CH Professional Edition for Raspberry Pi which is free for non-commercial use.

CH can be embedded in C and C++ application programs. It has numerical computing and graphical plotting features. CH is combined of both shell and IDE.[1] CH shell combines the features of common shell and C language.[2] ChIDE provides quick code navigation and symbolic debugging. It is based on embedded CH, Scite, and Scintilla.[3][4]
CH is written in C and runs on Windows, Linux, macOS, FreeBSD, AIX, Solaris, QNX, and HP-UX. It supports C90 and major C99 features, but it does not support the full set of C++ features. C99 complex number, IEEE-754 floating-point arithmetic, and variable-length array features were supported in CH before they became part of the C99 standard.[5][6][7][8] An article published by Computer Reseller News (CRN) named CH as notable among C-based virtual machines for its functionality and the availability of third-party libraries.[9]
CH has many tool kits that extend its functions. For example, the CH Mechanism Toolkit is used for design and analysis of commonly used mechanisms such as four-bar linkage, five-bar linkage, six-bar linkage, crank-slider mechanism, and cam-follower system.[10] CH Control System Toolkit is used for the design, analysis, and modeling of continuous-time or discrete-time linear time-invariant (LTI) control systems.[11] Both tool kits include the source code.
CH is now used and integrated into the curriculum by many high schools and universities to teach computing and programming in C/C++.[12][13][14][15][16][17][18] CH has been integrated into free C-STEM Studio, a platform for learning computing, science, technology, engineering, and mathematics (C-STEM) with robotics. C-STEM Studio is developed by the UC Davis Center for Integrated Computing and STEM Education, offering a curriculum for K-12 students.
CH supports LEGO Mindstorms NXT and EV3, Arduino, Linkbot, Finch Robot, RoboTalk and Raspberry Pi, Pi Zero, and ARM for robot programming and learning.[19][20][21] It can also be embedded into the LabVIEW system design platform and development environment.[22]
