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.
This means that its function is to pose a question to readers. You've likely seen them used in all types of writing, from fiction writing to nonfiction writing and from academic writing to personal writing.
