No.

Explanation:

If a question is also an exclamation then it may end with "?!"

For example:

Who do you think you are?!

In addition an answer may be invited by a statement, otherwise known as an indirect question. Then you would use a full stop instead of a question mark.

For example:

I wonder why you are asking this question.
