+# Create a script to parse URL and print the components of URL.
+# https://en.wikipedia.org/wiki/URL
+# According to Wiki page, the URL syntax is as below:
+# scheme:[//[userinfo@]host[:port]]path[?query][#fragment]
+# For example: jdbc:mysql://user:password@localhost:3306/pwc?profile=true#h1
+#   scheme:   jdbc:mysql
+#   userinfo: user:password
+#   host:     localhost
+#   port:     3306
+#   path:     /pwc
+#   query:    profile=true
+#   fragment: h1
+#
+# usage: $ perl ch-2.pl "jdbc:mysql://user:password@localhost:3306/pwc?profile=true#h1"

+# url containing all the components i.e. the example.
