'I can't believe you didn't call me.' This is an example of a declarative sentence.
Explanation:
A declarative sentence can be defined as one that simply makes or expresses a direct statement, in the present tense. It is a simple statement that ends with a full stop, like the one given in the above example.
An interrogative sentence is a question and ends with a question mark (e.g. Did you go to work today?).
An imperative sentence is one that presents requests or commands someone to do something and ends with a period/full stop (e.g. Open the door.)
An exclamatory sentence expresses strong emotions and ends with an exclamation point (e.g. That thunderstorm was scary!).
