== Why is this an issue?

The complexity of an expression is defined by the number of ``++AND++``, ``++OR++``.

A single expression's complexity should not become too high to keep the code readable.

=== Noncompliant code example

With the default threshold value of 3

C                   IF        (condition1 AND condition2)

C                             OR (condition3 AND condition4)
