I am perfectly confortable with pointers.

Formely, electricians worked by rules of thumb, but nowadays what is
important is temperature avareness to prevent fire hazards, and
isolation to prevent personal hazards. And the rulbook has become
larger and larger and depending more and more on knowledge due
to hard lessons learned.

Misra C is a set of rules or guidelines, there is no programming
language, tool or product that "is" misra c. As with all things
security, it is a process.

page 1, section 3, says:
This course also introduces you to the SPARK subset of the Ada programming language,
which removes a few features of the language with undefined behavior, so that the code is
fit for sound static analysis techniques.
So even ADA contains that.

Yes, whatever tool you have, you have to know it to wield it
successfully. If you know the thing by heart then you know
instinctively what is worth trying. That how the great mathematicians
do it, if you don't do it by heart, your associations will be to slow.

Well, that is the basis of science, all hypotheses are viable unless
they are proved wrong.
