You might recognize the code on the next page as being the wds.c program from the text and spell checker fame. Modify this program to print each word on a separate line with the phrase has double letters after any word that has the same letter twice adjacent to each other in the word.

For example, the input:

would output:

Ever really looked at the moon, Lloyd?

Ever

really has double letters

looked has double letters

at

the

moon has double letters

Lloyd has double letters
