Question

a. true b. false c. error d. none
true / false (11–18)

  1. comparison operators always return a boolean value.
  2. 6 >= 10 is true.
  3. booleans can only be true or false.
  4. the operator == checks if two values are exactly equal.
  5. 5 < 2 evaluates to false.
  6. the != operator means \less than or equal to.\
  7. you can compare strings using comparison operators.
  8. boolean expressions can be used inside if statements.

Explanation:

Brief Explanations
  1. Comparison operators (e.g., ==, >, < etc.) in programming return either True or False (Boolean values).
  2. \(6\) is not greater than or equal to \(10\). \(6<10\), so \(6 >= 10\) is False.
  3. By definition, Boolean data type has only two values: True and False.
  4. The == operator checks for value equality (in many programming languages, it may not check for strict type equality in some weakly - typed languages, but in terms of value comparison as per basic understanding of the operator's purpose).
  5. \(5\) is greater than \(2\), so \(5 < 2\) is False.
  6. The != operator means "not equal to", while <= means "less than or equal to".
  7. In many programming languages, strings can be compared lexicographically (e.g., in Python, Java) using comparison operators.
  8. if statements use Boolean expressions (conditions) to decide the flow of execution. If the expression is True, the block inside the if statement is executed.

Answer:

  1. a. True
  2. b. False
  3. a. True
  4. a. True
  5. a. True
  6. b. False
  7. a. True
  8. a. True
