Coding Adventure III Quiz

Which type of loop is used when the number of iterations is known?

• do-while loop

• For the question in English, the correct answer is 'for loop'.

• while loop

• if-else loop

What is the difference between 'while' and 'do-while' loops?

• There is no difference between 'while' and 'do-while' loops.

• In a 'while' loop, the condition is checked after the loop is executed, while in a 'do-while' loop, the condition is checked before the loop is executed.

• In a 'while' loop, the condition is checked before the loop is executed, while in a 'do-while' loop, the condition is checked after the loop is executed at least once.

• In a 'while' loop, the loop will always execute at least once, while in a 'do-while' loop, the loop may not execute at all.

How do you break out of a loop in coding?

• Using the 'break' keyword

• Pressing the escape key

• By deleting the loop

• Using the 'stop' keyword

What is an infinite loop and how can it be avoided?

• An infinite loop is a loop that only runs once and then stops

• An infinite loop is a loop that runs for a very long time and cannot be stopped

• An infinite loop is a loop that runs backwards

• An infinite loop is a loop that continues to execute indefinitely. It can be avoided by ensuring that the loop condition will eventually become false, or by using control flow statements like break or return to exit the loop.

What is the purpose of using 'continue' statement in a loop?

• The purpose of using 'continue' statement in a loop is to end the loop immediately

• The purpose of using 'continue' statement in a loop is to skip the current iteration and move to the next iteration without executing the remaining code in the loop for that iteration.

• The purpose of using 'continue' statement in a loop is to restart the loop from the beginning

• The purpose of using 'continue' statement in a loop is to execute the remaining code in the loop for that iteration

What is the output of the following loop: for i in range(5): print(i)?

• 0 1 2 3 4

• 5 4 3 2 1 0

• 0 1 2 3 4 5

• 1 2 3 4 5

What is the output of the following loop: while x < 5: print(x); x += 1?

• 7

• 6

• 0 1 2 3 4

• 5

How can loops be used to solve real-life problems?

• By ignoring the problems altogether

• By creating more problems instead of solving them

• By repeating a set of instructions multiple times to automate tasks and solve problems efficiently.

• By making the problems more complicated
