* Passing member function to argument of pointer-to-function type of functions

Ch can interact with existing C/C++ libraries and call C/C++ functions from Ch script.<ref>{{cite journalmagazine |last= Wilson |first= Matthew |year= 2004 |title= Open-RJ and Ch |url= http://drdobbs.com/184401877?queryText=ChSDK |publishermagazine= Dr. Dobb's Journal}}</ref>

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.<ref>{{cite journalmagazine |last= Cheng |first= Harry |year= 2009 |title= Speeding-Up Software Development Using Embedded Scripting |pages= 8 |url= http://drdobbs.com/architecture-and-design/212201774 |publishermagazine= Dr. Dobb's Journal}}</ref><ref>{{cite book |last1=Wang |first1=Li-rong |title=2009 IEEE 10th International Conference on Computer-Aided Industrial Design & Conceptual Design |pages=1127–1132 |last2= Bo |first2= Yo|last3=Hagiwara |first3= I |publisher= Computer-Aided Industrial Design & Conceptual Design, 2009.

Ch has a built-in string type (string_t) for automatic memory allocation and de-allocation. It supports shell aliases, history, piping, etc.<ref>{{cite journal |last= Campbell |first= Matt |year= 2003 |title= Ch, A C/C++ Interpreter – New possibilities for people who like C and Unix |url= http://www.mactech.com/articles/mactech/Vol.19/19.09/CInterpreter/index.html |publisher= MACTECH, the journal of Apple technology}}</ref><ref>{{cite book|last=Cheng|first=Harry|title=The Ch Language Environment|edition=6.3|year=2010|publisher= SoftIntegration , Inc.|___location=Davis, CA}}</ref>
