The Front-End Web Developer Bootcamp - HTML, CSS, JS, and React - Do While Loop

This video tutorial explains the differences between while and do while loops. It demonstrates how to initialize a loop, execute a do while loop, and highlights the key difference: a do while loop executes the statement before checking the condition. The tutorial also covers setting conditions and incrementing within loops, ensuring the loop runs as intended. The video concludes with a summary of the do while loop's functionality.

What is the main difference between a while loop and a do while loop?

• A do while loop checks the condition before executing the statement.

• A do while loop executes the statement at least once before checking the condition.

• A while loop executes the statement before checking the condition.

• A while loop does not require initialization.

In a do while loop, what happens if there is no increment or decrement in the loop variable?

• The loop will execute twice.

• The loop will not execute at all.

• The loop will execute indefinitely.

• The loop will execute only once.

How can you stop a do while loop from running indefinitely?

• By using a break statement.

• By initializing the loop variable to zero.

• By removing the condition.

• By adding an increment or decrement to the loop variable.

What happens when the loop variable exceeds the condition in a do while loop?

• The loop throws an error.

• The loop stops executing.

• The loop resets the variable.

• The loop continues to execute.

Which of the following is true about the execution of a do while loop?

• The loop cannot have a condition.

• The statement is executed at least once regardless of the condition.

• The loop must have a decrement.

• The condition is checked before the first execution.
