Essentially interjections and exclamations are the same thing. They are both parts of speech that exemplify some type of sudden emotion. Interjections are typically only a word or two long, while exclamations can be a sentence; basically, an interjection is simply a subcategory of exclamations. Some common interjections/exclamations include alas, oh (dear/boy/my), uh, well, no duh, and so on.

Dinner is ready, don't do that, drop your weapon and duck are exclamations. They begin with the letter d.
Lookout
Zap!
OY!
