In the syllabus it states that we have to understand the structure of arrays (one dimensional and two dimensional). I cant find an explanation anywhere in my book about two dimensional arrays :(. Can anyone explain?

2D arrays are in P2 .. should be under 2.3 or 2.2

magnetic card reader works in conjection with a magnetic strip located on the backside of cards
it contains data like account no amount contained etc
they swipe the card in the machine
reads the data on the magnetic strip
(after verification it displays the data and you can make changes
