What are the rules to be followed when punctuating sentences with parentheses?

Question

What will be an ideal response?

Answer 1

Parentheses may be used to enclose some of the words within a sentence, or they may be
used to enclose an entire sentence. No punctuation mark goes before the opening parenthesis
within a sentence. Whatever punctuation would normally be used at this point is placed after
the closing parenthesis. However, these rules do not affect any punctuation needed within the
parentheses. If an independent clause in parentheses within a sentence is a question or
exclamation, the question mark or exclamation mark is included within the parentheses. If the
independent clause is a declaration, however, no period is used within the parentheses. When
parentheses are included within a sentence, the first word in parentheses is not capitalized
(unless, of course, the first word is a proper noun) even if the words in parentheses are an
independent clause. When the words enclosed in parentheses are entirely independent (that
is, they are not part of another sentence), the first word in parentheses is capitalized and
normal end punctuation is used before the closing parenthesis.
