Problem Statement

Given a character value in your language, print its code   (could be ASCII code, Unicode code, or whatever your language uses).

The character   'a'   (lowercase letter A)   has a code of 97 in ASCII   (as well as Unicode, as ASCII forms the beginning of Unicode). Conversely, given a code, print out the corresponding character.

Let's start with the solution:

1> F = fun([X]) -> X end. 
#Fun<erl_eval.6.13229925>
2> F("a").
97


3> $a.
97
