      MISRA[^] Rule 33 & 34:

      The right hand operand of a || shall not contain side effects
      The operands of a logical || shall be primary expressions

      The example you gave is the very reason for the above two rules.

      ~RaGE();

      I think words like 'destiny' are a way of trying to find order where none exists. - Christian Graus Entropy isn't what it used to.

      There's actually some nice concise uses of

      var result = DoSomething() && DoSomethingThatDependsOnIt();
      var result = DoSomething() || HandleFailureCase();

      It's even better in languages where you can use non-boolean types with the boolean operators.

        Programming Quiz of the day. I just wrote this code (C#), which did something very unexpected. What was it that it unexpectedly did?

        		bool more = ProcessFlyouts();
        		more = more || ProcessCarrierAnimations();
        

        How would you change it to "do the right thing?" Marc

        Though Nish's and OG's examples will work, I think it is symantically better to do this:

        bool more = ProcessFlyouts();
        bool foo = ProcessCarrierAnimations();
        more = more || foo;

        Less terse code (normally bad) - but explicit in calling ProcessCarrierAnimations.

          more |= ProcessCarrierAnimations(); ?

          You'll never get very far if all you do is follow instructions.

                  var more = more || initalizeMore(); is a common practice in javascript.

                    This isn't a change from C++. It works the same way for both operators. Doesn't it? Now I'm going to have to read up on it, dammit!

                        Now, I'm not going to look at the other answers before I post so I don't know if others have got it right, or if there are additional nuggets of information. If ProcessFlyouts returns true then the second test isn't carried out - it's a conditional OR statement. So, if you want ProcessCarrierAnimations to be evaluated, convert it to

                        more = more | ProcessCarrierAnimations();

                          You have to! Otherwise you may end up with some mess if updating C/C++ to C# (what I'm doing just now)...

                                      Is it just me that would have done it as a oneliner?

                                        That could make setting a breakpoint on the second call difficult. :shrug:

                                        You'll never get very far if all you do is follow instructions.

                                          No big deal to change if necessary. :shrug: But I actually find it easier to read on one line.
