Ch can be embedded into the 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 MSDOS,common Unix Shellshell and C language.<ref>[http://www.softintegration.com/docs/ch/shell/ Ch Shell]</ref> ChIDE provides quick [[code navigation]] and step-by-stepsymbolic debug featuresdebugging.

Ch can also be run as an interactive shell to execute C statements and scripts.

Unix commands can run in Unix Ch shell, and Windows commands can run

in Windows Ch Shell.<ref>{{cite journal | last = Wang | first = Gary | year = 2002 | title = Ch Solves Portability Headaches | url = http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=1049264 | publisher = IEEE Spectrum}}</ref>

Ch is written in C and runs under [[Microsoft Windows]], [[Linux]], [[Mac OS X]], [[FreeBSD]], [[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 [[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>
