    What a beautiful scene!

    Imp: Sometimes question and exclamatory sentences get confusing. Keep in mind in questions helping verb comes before the subject in the sentence while in exclamatory sentence helping verb comes after the subject.

    What are you eating?
    This is a question so question mark should be used.

    What you are eating!
    As helping verb is not before the subject, it is not a question but an exclamation.
