Re: how cast works?

I don't know what happens when you're changing datatype lengths, but if
they're the same length, it's just telling the compiler what the
variable should be treated as (e.g. [8-bit] int to char)

  Casting doesn't tweak a value right where it sits, so you don't
  have to stress about resizing memory. (It hands you an rvalue,
  not an lvalue.)

  Casting isn't just about variables; it's all about expressions.

  The whole casting concept hails from Algol.

  Basically, casting is like flipping a value from one type
  to another (as specified by the cast).

  But you got to tackle each pair of data types on its own,
  and that's way more than we can dive into here!
