Helix QAC

{{Refimprove|date=September 2014}}

Helix QAC, formerly QA·C is a commercial static code analysis software tool produced by Minneapolis, Minnesota-based software vendor Perforce Software. QAC means Quality Assurance and Control. The software was originally developed in 1986 by UK-based Programming Research Limited (PRQA) for the C language. Perforce acquired PRQA in May 2018.{{cite web|url=https://www.pehub.com/2018/05/clearlake-backed-perforce-software-acquires-programming-research/# |title=Clearlake-backed Perforce Software acquires Programming Research |website=pehub.com |date=2018-05-02 |accessdate=2018-07-09}}

Helix QAC was used to make the C source code measurements given in the book Safer C by Les Hatton.{{cite book|last=Hatton|first=Les|title=Safer C: Developing Software in High-Integrity and Safety-Critical Systems|publisher=McGraw-Hill|date=1995|isbn=0-07-707640-0}}

HeliX QAC can be used for quality assurance of C source code and checking the code for conformance to coding guidelines such as MISRA C. Other functionality includes the ability to calculate code metrics for projects with large code-bases.

The tools operate through an integrated development environment (IDE) designed to help maintain and understand old and new code using detailed cross references and a variety of graphical views.

The tools can be used with a command line interface, and graphical IDE can be called to display the result.{{cn|date=November 2018}}
