PC-lint is a commercial software linting tool produced by Gimpel Software for the C/C++ languages.

PC-lint is a command-line tool for performing static code analysis, indicating suspicious or plain wrong issues in source code. PC-lint can be integrated into IDEs as an external tool, and the format of the warning messages can be adapted to the form the IDE is able to recognize and process. It is advertised as running on Microsoft Windows and OS/2. A separate multi-platform version called FlexeLint is also available for Unix and other platforms, albeit at substantially greater cost.
