2.20. Repeating Strings

In Ruby, the multiplication operator (or method) is overloaded to enable repetition of strings. If a string is multiplied by n, the result is n copies of the original string concatenated together:

etc = "Etc. "*3                        # "Etc. Etc. Etc. " ruler = "+" + ("."*4+"5"+"."*4+"+")*3 # "+....5....+....5....+....5....+"
