        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 (condition2 AND condition2)
        C                             OR (condition3 AND condition4)
        
         /free
           IF A=X OR A=Y AND A=Z AND B=Y OR B=Z;
                ...
           ENDIF;
         /end-free
        

        Compliant solution

        C                   IF        (condition1 AND condition2)
        C                             OR MyComplexCondition()
        
         /free
           IF A=X OR MyComplexCondition() OR B=Z;
                ...
           ENDIF;
         /end-free
