what are you trying to do? the &amp;&nbsp;symbol is for bitwise and, not the logic and (&amp;&amp;) I hope you know that.

what are you trying to do? the & symbol is for bitwise and, not the logic and (&&) I hope you know that.

<div>
You are mixing logical (!) and bitwise (&amp;) operators in an expression. It is a very error-prone practice because of the implicit conversions back-and forth so I'd advise you to stick to one or the other or make explicit conversions.<br />
<br />
Are you sure that you don't mean to use the bitwise negation (~) rather than ! (logical negation). ~ will revert each individual bit whereas ! always will result in either 0 or 1.<br />

To C++ Experts,

   How do I calculate things like :
  int x = !(!3 & !8) ; 
 thanks ....

meow.

! in arithmatic calculations ?

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
