SonarQube C/C++/Objective-C 4.2 发布了，这是一个C/C++/Objective-C的插件，用于检查代码质量。
这个版本提供了以下的新规则：
“nonnull” pointers should not be set to null (C, Bug)
“switch” statements should cover all cases (C++, C, Objective-C, Code Smell, suspicious)
File names should comply with a naming convention (C++, C, Objective-C, Code Smell, cert, convention)
GNU extensions should not be used (C++, C, Objective-C, Code Smell, lock-in, obsolete)
Overriding virtual functions should be declared with “virtual” (C++, Code Smell, misra)
Reference types should not be qualified with “const” or “volatile” (C++, Code Smell, cert, lock-in, unused)
Unused function parameters should be removed (C++, Code Smell, cert, misra, unused)
Virtual functions should not have default arguments (C++, Code Smell, api-design, cert, pitfall)
