Why can't I use the '|' bitwise operator in this statement? in c/[email protected]

Thank you for the thorough explanation. It makes sense to me why I had the error that I did. I'll keep this in mind next time when I consider using a bitwise operator.

Thank you for the reply. It seems bitwise operators are somewhat of an advanced concept that I may revisit down the road.

Thanks. I think I understand why I wouldn't want to use it in this case. But what is an example of where I can use it? This makes me think I should avoid using bitwise operators with integers and keep it to strings only, but I know that's not true from what I've learned.

Thank you. Not sure why in the link the arithmetic in green results in 7.

Thank you for breaking it down.

I'm just now sure when it is appropriate to use '|'. If bitwise operators can only be used with integers (and not floats), what's an example where I can use it.

Yes I did eventually think of that as well but just wanted to understand why '|' wasn't producing the results I expected.

I did come across that link but didn't quite understand it. If looking only at 25 | 10, does the code not run as expected because 25 is 5 digits long and 10 is 4 digits long? Is that what's meant by "two equivalent length bit designs"?

Also, I can't tell if 10 | 4 = 7 or 10 | 4 = 14.

if coin == 25 | 10 | 5:

If I replace the '|' with 'or' the code runs just fine. I'm not sure why I can't use '|' in the same statement.

Doing the following doesn't work either:

if coin == 25 | coin == 10 | coin == 5:

I know bitwise operators can only be used with integers, but other then that is there another difference from logical operators?

I am getting traceback errors for any expression (1 + 1) I enter.
