 == Why is this an issue?
 
-While working with bitwise operators ``++&++`` or ``++|++`` it is easy to make a typo and write the equivalent logical operators ``++&&++`` or ``++||++``. This rule is raising issues when the right operand of a logical expression  ``++&&++`` or ``++||++`` is a constant of integral type, as the developer probably meant to use the corresponding bitwise operator ``++&++`` or ``++|++``.

 ----
 int fun(int a) {
