Chp. 4 Alice Loop Structures

Which type of structure is used to execute the same set instructions more than once?

• Decision structure

• Sequence structure

• Repetition structure

• Do together structure

• None of these

The following loop would execute how many times? Loop index from 0 up to (but not including) 3 times incrementing by 1

• 1

• 2

• 3

• 4

• None of these

The following loop would execute how many times? Loop index from 0 up to (but not including) 4 times incrementing by 2

• 1

• 2

• 3

• 4

• None of these

The following loop would execute how many times? Loop 1 times times

• 1

• 2

• 3

• 4

• None of these

Which type of instruction will cause a set of instructions to execute as long as a specified Boolean expression is true?

• If/Else

• Loop

• Repeat

• While

• None of these

Which of the following is an example of an infinite loop?

• for (int i = 0; i < 10; i++) { }

• while (true) { }

• for (int i = 0; i < 10; i--) { }

• do { } while (false);

Which of the following is a valid While loop condition?

• While 1 > 2

• While 2 < 1

• While 1 == 1

• Loop 1000 times times

• None of these

This is the type of variable that the Loop instruction uses internally.

• Register

• Counter

• Matrix

• Address

• None of these

Because the condition is tested before the loop is repeated, what is another term for the While instruction?

• Counter-controlled loop

• Infinite loop

• Posttest loop

• Pretest loop

• None of these

Because programmers commonly need to repeat instructions, all programming languages provide repetition structures.

• True

• False
