The exclamation mark (!), also known as the "bang" symbol, is used as an indicator of emphasis, strong emotion, or surprise. It usually appears at the end of a sentence or declaration; for example, "Click here!" or "What?!". The exclamation mark is also often present in titles and headings, usually with words that have strong connotations. This exclamation mark has been used since the 15th century and appears in many printed books.
