Hi,

Can you tell me why am I wrong for me in the question #17 ?

Hi Laurent,

It is wrong because you’re not calling a function. You’re broadcasting a message which is picked up by delegates and then executed.

It’s a fine line but ultimately, you are not actually calling the function on another class yourself. You could argue that you are indirectly calling it, but still you are not calling that function.

Please can you remove the image from your post as it may spoil others attempts at answering questions and gives them answers. Generally we ask users to not post the quiz questions/answers.

Thanks for the answer,
So I was wrong, I did not see the difference. And I’ve learned something.
I removed the image .
Sorry, I also did not thought about the spoil.

Thanks for removing the image. I appreciate it. The quiz is tricky but the course is too.
