If a do... while structure is used a. An off-by-one error cannot occur b. An infinite loop cannot take place. c. The body of the loop will execute at least once. d. Counter-controlled iteration is not possible. Which of the following data types cannot be used to represent integers? a. short b. long c. string d. char A switch statement should be used. a. To replace all if.. else statements. b. As a single-selection structure c. As a double-selection structure. d. As a multiple-selection structure In a logical (&&) operator, if conclusion 1 is true, condition 2 is false, then condition 1(&&) condition2 evaluate to: a. True b. False In a logical operator, if conclusion 1is true, conditional2 is false, then condition 1 condition2 evaluates to a. True b. False The operator a. Has higher than the (&&) operator b. Association from right to left c. Stops evaluation upon finding one condition to be true d. Has at least four conditional statements. The for loop statements are used in controlled iteration and the while statements are used for counter controlled iteration a. True b. False Which of the following is not one of the C++ control structures? a. If b. switch c. break d. do... while Which of the following statement is false? a. An expression containing the is false, if either or both of its operands are true. b. The default case is optional in the switch selection structure. c. The break statement is used to exit the switch statements. The break statement is not required when the default case is the last case. d. The expression (x > y && a y is true or the expression a

Explanation / Answer

15. Ans: c. The body of the loop will execute at least once.

do...while loop checks its condition at the bottom of the loop,so that loop will execute at least once.

16. Ans: C. string & D. Char

Short and long are representations of integers.

17.Ans: A. To replace if ...elese statements

18. Ans: False.

The condition per The logical AND operator (&&) returns the boolean value true if both operands are true and returns false otherwise.

19. Ans: True.

20. Ans: b.Association from right to left

21. Ans: False.

22. Ans:b.Switch
There is no switch statement in c++

23.Ans: A
