Cppcheck is an open source tool for static C/C++ code analysis that tries to detect bugs that a C/C++ compiler doesn't see.

Cppcheck - A tool for static C/C++ code analysis

Cppcheck is an analysis tool for C/C++ code. Unlike C/C++ compilers and many other analysis tools, we don't detect syntax errors. Cppcheck only detects the types of bugs that the compilers normally fail to detect. The goal is no false positives.

Rulesets for cppcheck

Cppcheck allows you to create your own rules files, but I don't know how much of cppcheck's functionality is exposed. Is anyone working on a set that would enforce JSF or MISRA rules?

Recommended way to track down array out-of-bound access/write in C program

Consider writing implementation for some not-so-obvious algorithm in C. For example let it be recursive quicksort, that I have found in K. N. King's "C Programming: A Modern Approach, 2nd Edition" book, that it's available from here. The most…

I call cppcheck on our own files in our source base. However, some source files include header files from third party libraries, say from ./lib/some_library/. These are automatically parsed by cppcheck as well. I don't want this, since I don't want…
