CLEAN : Aftermath of typhoon Hato in Macau

What is the primary purpose of a 'While' loop in programming?

• To execute a block of code as long as a condition is true

• To execute a block of code a specific number of times

• To execute a block of code based on user input

• To execute a block of code only once

Which of the following best describes how a 'While' loop operates?

• It checks the condition before executing the loop body

• It executes only if the condition is false

• It runs indefinitely without any condition

• It checks the condition after executing the loop body

In which scenario would you use a 'While' loop?

• When the number of iterations depends on a condition

• When you need to iterate over a collection

• When you want to execute a block of code once

• When you know the exact number of iterations needed

What is a potential risk of using 'While' loops?

• They are slower than 'For' loops

• They are not supported in all programming languages

• They can lead to infinite loops if the condition never becomes false

• They cannot handle complex conditions

Which of the following is an example of an advanced use of 'While' loops?

• Iterating over a fixed array

• Reading data from a file until the end is reached

• Executing a block of code a set number of times

• Using a 'While' loop to replace a 'For' loop
