Hi,
I am a C programmer and have to comply the code with MISRA 
<http://en.wikipedia.org/wiki/MISRA_C> rules.
According to these rules programmers should not rely on precedence of the
operators. They state to use [redundant] parenthesizes () instead.
So when an expression is too complicated, ( and ) would be in help.

Yup.  The way &amp;&amp; and || work is like almost all other languages.  But
because "and" and "or" has lower precedence and "and" has the same
precedence as "or", I almost never use them.  (If you switch from
language to language, you know what I mean.)
