cmp is a function used by Sort to determine if an argument is less than another. You write this function.

For examples you can write a class Bank to rappresent an bank account...if you have N objects and you want sort them, you can decide how to do it. You want order them according money? Or according creation date? You have to write a function that accepts two Bank objects and return a bool value. And in this function you choose what make an object smaller than another.
