Ch Programming Language: A Versatile Tool for Learning and Professional Use
Ch is a proprietary, cross-platform interpreter and scripting language environment that has gained significant attention for its ability to bridge the gap between beginner-level programming and professional software development. Initially created by Harry H. Cheng, Ch was designed as an educational tool to introduce students to the intricacies of computing, numerical analysis, mathematics, and programming in C/C++. Over time, it has evolved into a powerful tool with a diverse range of applications. From its early days as a learning tool to its current status as a platform supporting professional-grade software development, Ch has made notable contributions to the field of computer programming.
Origins and Development
Ch was originally conceived as a scripting language for novice programmers, with the primary goal of easing them into the complexities of C/C++ programming. It was designed to be easy to use, yet powerful enough to handle advanced tasks like numerical computations, graphical plotting, and system integration. The language was first introduced in 2001 and was developed by SoftIntegration, Inc., a company dedicated to creating software tools that facilitate mathematical computing and numerical analysis. While it started with the aim of helping students learn programming, it quickly found a broader audience due to its versatility and robust feature set.
Today, Ch is available for free in a student edition and can be used on a variety of operating systems including Windows, Linux, macOS, FreeBSD, AIX, Solaris, QNX, and HP-UX. SoftIntegration also provides a professional edition for Raspberry Pi, which is available for non-commercial use, further demonstrating the language’s accessibility for educational and personal projects.
Core Features of Ch

C/C++ Integration
Ch is based on C and supports most of the C90 standards and significant features from C99. It does not, however, support the full suite of C++ features, which limits its utility for developers looking to use advanced C++ features. That said, its compatibility with C and partial compatibility with C++ makes it an excellent starting point for those learning the C family of languages. -
Numerical Computing and Plotting
One of the distinguishing features of Ch is its ability to perform numerical computing and generate graphical plots. This makes it ideal for applications that involve scientific computing, such as simulations, data analysis, and mathematical modeling. -
Embedded Systems Integration
Ch can be embedded within C/C++ application programs, providing a scripting layer that enhances the capabilities of these applications. This feature is especially useful in developing software for embedded systems or applications where scripting can augment the core functionality. -
Graphical User Interface (GUI) Tools
Ch includes an integrated development environment (IDE) called ChIDE, which provides features like code navigation, symbolic debugging, and quick access to frequently used functions. The IDE is based on a combination of embedded Ch, Scite, and Scintilla, making it user-friendly and efficient for both novice and advanced users. -
Toolkits for Advanced Applications
Ch offers a wide range of toolkits designed to extend the language’s functionality in specialized areas. These include:- Mechanism Toolkit: Used for the design and analysis of mechanical systems such as four-bar and five-bar linkages, crank-slider mechanisms, and cam-follower systems.
- Control System Toolkit: Helps model, design, and analyze continuous-time and discrete-time linear time-invariant (LTI) control systems, which are crucial in fields like robotics and automation.
-
Support for Robotics and Embedded Development
Ch’s support for robotics is another of its standout features. It is compatible with platforms like LEGO Mindstorms NXT and EV3, Arduino, Raspberry Pi, and various other robotics tools. This capability makes it a useful tool for teaching and developing robotic systems in educational environments, especially in conjunction with the C-STEM Studio platform developed by UC Davis. -
Educational Integration
Ch is used by many high schools and universities as part of their computing curriculum. Its ability to bridge the gap between beginner and advanced levels of programming, combined with its support for numerical and graphical computing, makes it a popular choice in STEM education. The free student edition allows institutions to introduce students to programming in a hands-on way, without the barriers of expensive proprietary software.
Applications of Ch
Ch’s ability to function as both a scripting language and an interpreter gives it a unique position in the world of programming languages. It is used in a variety of fields, including:
-
Education
Ch has found a prominent place in educational institutions as a teaching tool for computing, programming, and mathematical modeling.
