I'm having trouble understanding exercise 8.1 of Arrays.
According exercise 8.1, does the user need to enter 3 types of information: ID code, number of persons and yearly income? And if that's that case, where would I get the ID code, or do I make up the numbers?
Unfortunately, in my opinion, the author's did not give much information on this exercise to which what they are asking is unclear to me.
I am trying to understand what is required of me in this assignment. Thank you.
