I am a C (not C++ hobbyist), and I try to read up on standards and style guides to understand what I should be trying to do. Given that Misra has a C:2012, does anyone know how this compares to SEI Cert C Coding Standard (which im reading right now along with Secure Coding in C and C++)?
Definitely a generalisation, but i would see them as two sides of the same coin.
If Cert has something about an API, then it will have an example of misuse of it and then an example showing its correct use.
MISRA might either prohibit it's use completely (if there's a safe alternative), or with require some boilerplate step be taken every time the API is used.
