Which operator is used to negate a boolean condition?

• A. &&
• B. ||
• C. !
• D. ~

Answer: (C)

Negating a boolean condition means flipping its truth value: true becomes false, and false becomes true. The operator that does this is the logical NOT, written as an exclamation mark. So you’d see something like if (!condition) to mean “do this when condition is false.” The other operators perform different things: && requires both sides to be true, || requires at least one side to be true, and ~ is a bitwise NOT that operates on numbers rather than a straightforward boolean condition. That’s why the logical NOT operator is the appropriate choice for boolean negation.
