Which of the following operators has the highest priority?

The operator with the highest priority among those listed is unary + and -. Unary operators, which include the unary plus (+) and unary minus (-), have a higher precedence than binary operators like addition and subtraction, as well as multiplication and division, and even comparison operators.

This means that when evaluating an expression, unary operations are processed before binary operations or comparisons. For example, in an expression that involves both unary and binary operations, the unary operators will take effect first, allowing for the correct evaluation of the expression's overall value.

Additionally, while multiplication and division typically have higher precedence than addition and subtraction, neither surpasses the precedence of unary operators. Similarly, comparison operators, which include relational operations like greater than or less than, also do not have the priority that unary operators possess.

Understanding operator precedence is crucial for correctly evaluating expressions in programming, as it ensures that operations are performed in the intended order, leading to expected results.
