In American English, a period is not added at the end of a sentence if it ends with a quote whose last letter is a quotation mark or an exclamation point.
Edema asked, "Am I an alliteration addict?"
Should the period at the end of the quote be added, if the sentence ends with a question mark or an exclamation point? Is the following sentence correct?
Did Edema said, "I am an alliteration addict."?
