Hello,
We did an effort in 2019 to better cover the MISRA standards, especially MISRA C++ 2008 and there are today 50 rules for C++ for this specific version of the standard: https://rules.sonarsource.com/cpp/tag/misra-c++2008. You can check my latest post about the topic published in October 2019 here.
But we offer more than these 50 rules with the support of C++ Core Guidelines and in total it’s 440+ rules you can use to make sure your C++ code is maintainable and reliable.
You can get access to these checks on SonarCloud.io and with SonarQube Developer Edition.
Regards
Alex
