Maybe, if I could see the content of both methods that return a bool :) Otherwise, quite hard to detect a logic issue when the logic itself is not told.

[Flags]
public enum Bool {
True, False, ForSure, Maybe, ProbablyNot, Depends, NotDecidedYet, Undefined
}

private interface IStealth { }

It will run either ProcessFlyouts, or ProcessCarrierAnimations, or neither, and the variable will tell you if it successfully ran either. I would imagine you either want && or |.

[OriginalGriff]

I assume you meant it to do this:

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

:laugh: Would do the same in C and C++ as well.

I assume that you want to run the second method if first returns true, if that the case you have to switch the order

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

I'm not questioning your powers of observation; I'm merely remarking upon the paradox of asking a masked man who he is. (V)

Exactly. :)

Yup! Marc

Quite so. The bitwise | operator solves the problem too. Marc

Yes indeed. Or use the bitwise operator. Marc

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.

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.

[OriginalGriff]

Yes - but I don't like bitwise operators with bools...

Yep, but this is a workaround, not a best practice though.

I do not like that change from C/C++...I mean the | and || changes... X|

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.

[Keith Barrow]

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.

Let's say I have never seen these two lines of code, OK ?

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