Answer 1

ahhhh so since a has a [] it<gives value of 5 which is same as 1 meaning true?

Answer 2

On short, yes

Answer 3

The code gives an error, but from the looks of it, the reason could be the fact that comouters store the value true as 1 and the value false as 0 and printing will give the item at the index 1, which is 5.
