Ch can be embedded in C/C++ application programs. It has numerical computing and graphical plotting features. Ch is a combined shell and IDE.<ref>{{cite journal |last= Veeraraghavan |first= Sriranga |year= 2013 |title= An introduction to Ch: Implementing a temperature converter in Ch |url= http://www.techworld.com.au/article/452524/an_introduction_ch_implementing_temperature_converter_ch/ |publisher= ComputerWorld}}</ref> Ch shell combines the features of common shell and C language.<ref>[http://www.softintegration.com/docs/ch/shell/ Ch Shell]</ref> ChIDE provides quick code navigation and symbolic debugging.

Ch is written in C and runs on [[Microsoft Windows|Windows]], [[Linux]], [[OS XmacOS]], [[FreeBSD]], [[IBM AIX|AIX]], [[Solaris (operating system)|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.<ref>{{cite journal |last= Cheng |first= Harry |year= 1993 |title= Handling of Complex Numbers in the Ch Programming Language |pages= 76–106 |url= http://iospress.metapress.com/content/xml874m51x1w42w0/|journal=Scientific Programming}}</ref><ref>{{cite journal |last= Cheng |first= Harry |year= 1993 |title= Scientific Computing in the Ch Programming Language |pages= 49–75 |url= http://iospress.metapress.com/content/f225771541203807/ |publisher= Scientific Programming}}</ref><ref>{{cite journal |last= Cheng |first= Harry |year= 1995 |title= Extending C and FORTRAN for Design Automation |pages= 390–395 |url= http://scitation.aip.org/getabs/servlet/GetabsServlet?prog=normal&id=JMDEDB000117000003000390000001&idtype=cvips&gifs=yes&ref=no |publisher= ASME Trans., Journal of Mechanical Design}}</ref><ref>{{cite journal |last= Cheng |first= Harry |year= 1995 |title= Extending C with arrays of variable length |pages= 375–406 |url= http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6TYV-3Y6PCHF-V&_user=10&_coverDate=09%2F15%2F1995&_alid=1737140035&_rdoc=1&_fmt=high&_orig=search&_origin=search&_zone=rslt_list_item&_cdi=5628&_sort=r&_st=13&_docanchor=&view=c&_ct=1&_acct=C000050221&_version=1&_urlVersion=0&_userid=10&md5=1369ffa56fdef3033135fa8fc1eb4c15&searchtype=a |publisher= Computer Standards & Interfaces |doi=10.1016/0920-5489(95)00007-H |journal= Computer Standards & Interfaces |volume= 17 |issue= 4}}</ref> An article published by ''Computer Reseller News'' ([[CRN Magazine|CRN]]) named Ch as notable among C-based virtual machines for its functionality and the availability of third-party libraries.<ref>{{cite journal |last= Morejon |first=Mario |year= 2006 |title= Ch Language Rivals Java Functionality |url= http://www.crn.com/reviews/applications-os/175804126/ch-language-rivals-java-functionality.htm |publisher= CRN}}</ref>

Ch has many toolkits that extend its functions. For example, Ch Mechanism Toolkit is used for design and analysis of commonly used mechanisms such as fourbar linkage, five-bar linkage, six-bar linkage, crank-slider mechanism, and cam-follower system.<ref>{{cite journal |last= Cheng |first= Harry |year= 2006 |title= Object-Oriented Interactive Mechanism Design and Analysis |pages= 237–246 |url= http://link.springer.com/article/10.1007%2Fs00366-005-0008-4 |publisher= Engineering with Computers}}</ref> Ch Control System Toolkit is used for modeling, design, and analysis of continuous-time or discrete-time linear time invariant (LTI) control systems.<ref>{{cite journal |last= Zhu |first= Yong |year= 2003 |title= An Object-Based Software Package for Interactive Control System Design and Analysis |pages= 366–367 |url= http://computingengineering.asmedigitalcollection.asme.org/article.aspx?articleid=1399866f |publisher= ASME Trans.
