Programming Loops Activity

What does iteration mean?

• A type of data structure

• Repetition of a section of code

• A single execution of a program

• A mathematical operation

What are three types of loop that can be used in programming languages for iteration?

• FOR, IF, ELSE

• WHILE, SWITCH, DO-WHILE

• FOR, WHILE, REPEAT UNTIL

• REPEAT UNTIL, FOREACH, IF ELSE

What is the purpose of a FOR loop in programming?

• To execute the loop based on a range of values

• To execute the loop while a certain condition is true

• To execute the loop a specified number of times

• To execute the loop until a certain condition is true

What is the purpose of a WHILE loop in programming?

• To execute the loop until a certain condition is true

• To execute the loop a specified number of times

• To execute the loop based on a range of values

• To execute the loop while a certain condition is true

What is the purpose of a REPEAT UNTIL loop in programming?

• To execute the loop based on a range of values

• To execute the loop until a certain condition is true

• To execute the loop a specified number of times

• To execute the loop while a certain condition is true

What is the purpose of using STEP with FOR loops?

• To skip every other iteration of the loop

• To add a random number to the iterator

• To reverse the direction of the loop

• To control the number of times the loop is executed

How many times will a WHILE loop be executed if the condition is always true?

• Twice

• It will continue forever

• Once

• Depends on the specific condition

What type of loop is known as a pre-condition loop?

• FOR loop

• WHILE loop

• REPEAT UNTIL loop

• DO-WHILE loop

What type of loop is known as a post-condition loop?

• DO-WHILE loop

• REPEAT UNTIL loop

• WHILE loop

• FOR loop

How can a REPEAT UNTIL loop be used to repeatedly ask a user to enter their name until it is longer than one letter?

• Use a counter to determine the number of iterations

• Check the condition at the end of the loop

• Use a random number to control the loop

• Check the condition at the beginning of the loop
