The exclamation mark (British English) or exclamation point (American English) is a punctuation mark usually used after an interjection or exclamation to indicate strong feelings or high volume (shouting), and often marks the end of a sentence.
He shouted, Hello!. An exclamation mark indicates that something was exclaimed. It should generally only be used in spoken dialog, when someone is angry, excited, or frustrated. It should almost never be used in technical writing, or in narrative text. For example, Larry walked to the store! He was very excited! He shouted, Hello.. is an inappropriate use of exclamation marks.
