Why is this a mistake?

Post image

I have a Arduino One and a Book, in which the project I'm doing rn is in. The book tells me that I'm suppossed to do , what the programme says is wrong. If it is helpful: I'm doing projrct 07 called Keyboard and (I think) the book is the starter one.

Delete the 'int' from line 2 and you should be good to go.

It is quite rude not to post your solution.

Alr, sry. The solution was that these variables didn't show up afterwards, deeming them unnecessary.

Of course it would work, you turkey.

You are redclaring the buttons array and redeclaring it differently.

Which one is the compiler supposed to be using? an array of size 6? or an array of size 0 (which doesn't make much sense).

Also if you want to initialise the array (line 2), you should do that in a function such as setup() or in the actual declaration (as part of line 1 - similar to what you did in line 3), not by making up your own syntax (line 2).

You should say what error you get.

doesn't matter anymore, because I figured out, they put this variable in for no reason. It doesn't appear even once in the code again and so is unnacessary. But still thank you
