Week 5 Quiz

For this week's lecture, we looked at loops. Which of the following is NOT a loop?

While loop

Do-while loop

If loop

For loop

Clear selection

The do-while loop enforces one additional function as compared to the while loop. Which of the following best describes this function?

Allows the loop to run at least one time

Allow the loop to run one less time than the while loop

Allows the loop to run twice the amount of times than the while loop

The do-while loop is the same as the while loop

Clear selection

Using a loop, we can run code within a loop several times without the need to replicate the code. Which of the following for loop implementation will run for 10 times?

Assume that integer i has already been declared beforehand

for ( i = 5 ; i <= 15 ; i++)

for ( i = 99 ; i > 90 ; i -- )

for ( i = 0 ; i <= 10 ; i++)

for ( i = 12 ; i < 22 ; i++)

How many times will the above code iterate?

Assume that integer i has already been declared and initialised to 0.

8999

9000

9001

There is a syntax error in the code.

Last week, the "break" keyword was introduced. This week, it was highlighted again for using in loops. What does the "break" implementation do in a loop?

Break and end execution of the program

Break out from the loop and execute code following the loop

Break out from the function which contains the loop

The break statement does not affect loops

Clear selection

This week the "continue" keyword was introduced. What does the "continue" do within the loop?

Skip to the next iteration within the loop

Tells the program to continue to the next line of code after the keyword

Restart execution from the main function

Continue is just another notation for break

In most programs, we try to prevent our logic from creating infinite loops as it can impede the general flow of our code. During the implementation of the code above, will the loop iterate infinitely?

Assume that iAmHandsome is an integer

Yes

I don't have enough information to make a decision

I like gardening
