Date Formatting
April 16, 2013
In many programming languages, dates have a kind of “second class” relationship to data types such as integers, characters, strings and arrays; functions related to dates, such as finding the number of days between two dates, may be relegated to libraries or omitted entirely. Our Standard Prelude provides a few simple date functions, but missing is a function to neatly format a date.
Your task is to write a function that takes a date and returns a neatly-formatted string representing the input date; your function may be as simple or as elaborate as you wish. When you are finished, you are welcome to read or run a suggested solution, or to post your own solution or discuss the exercise in the comments below.
