I'm misunderstanding something...

Question

Why would the output be false for the array -1?

Answer 1

@Rachel.

a[-1] is used to access the variable in the list from the end. So, a[-1] is the same as a[3] which is false.

Similarly, a[-2] =15.88

This flexibility in indexing is very useful when you code.

Answer 2

Could you explain; post a code maybe?

Answer 3

yes,

In the language Ruby, we have the array.

arr=[5,"Dave",15.88,false]

I am going to skip to the portion that I don't understand the output to, which is puts arr [-1] #false.

I could go in circles about why I don't understand. :(

Answer 4

Thank you.
