Question 1

Given the for loop header below, how many times will the loop repeat?

for(int counter = 5; counter < 10; counter++)

5 times

6 times

2 times

10 times

Question 2

Which of the following loops will calculate the sum of all of the numbers from 1 to 10, including 1 and 10. You can assume that sum has been initialized to a starting value of 0.

for(int counter = 0; counter < 10; counter++)

sum = sum + counter;

for(int counter = 1; counter < 10; counter++)

sum = sum + counter;

for(int counter = 1; counter <= 10; counter++)

sum = sum + counter;

for(int counter = 0; counter <= 10; counter)

sum = sum + counter;

Question 3

Which statement can be used to skip the remainder of the loop body for a single iteration, without exiting the entire loop (that is, the loop may repeat again if the condition is still true)?

break

continue

skip

None of the above

Question 4

If the loop control variable of a while loop is not modified within the body of the loop, the loop will default to incrementing the value by +1 on each iteration.

True

False

Question 5

Given the while loop below, how many times will the loop body execute?

counter = 10;

while (counter < 10)

{

counter = counter - 1;

}

0 times

1 time

9 times

10 times

Question 6

The break statement can be used to provide an alternative exit condition for a loop, as it terminates the loop immediately without returning to evaluate the condition.

True

False

Question 7

Given the for loop header below, how many times will the loop repeat?

for(int i = 10; i > 0; i = i - 3)

10 times

4 times

0 times

The loop is infinite

Question 8

What is the output of the while loop given below?

counter = 5;

while(counter != 0)

{

cout << counter << endl;

counter = counter - 2;

}

All of the integer values from 5 to 1

All of the odd numbers from 5 to 1

The loop is infinite.

Nothing, the loop never begins.

Question 9

If you needed to write a loop whose body should always execute at least one time, and then will repeat conditionally based on user input, which of the C# supported loops would be the most appropriate?

while

do-while

for

None of the above.

Question 10

The do-while and for loops are examples of post-test loops, which test the condition after executing the body for the first time.

True

False
