By permanently, do you mean after the program finishes running? What
you are looking for is called "backing store", such as file systems,
databases and the like were intended for: to enable the persistence of
data across program/script execution. Deciding what type of backing
store to use depends on the program's needs, the possibilities are
many.

If you are just starting out in this, I guess I'd recommend first
learning how to read and write to a file.
