> If we just concatenate the values in memory, how do we know where one line ends and the next begins? For instance, maybe the first two names are "jim" and "bob" or maybe it's one person named "jimbob", or even two people named "jimbo" and "b".

Don't we have a newline character? I thought we can read newline as `0xA` in Rust?
