Answer:
The difference between While loop and Do - While loop are explained below.
Explanation:
- While loop : It is a looping procedure in which the statements inside the while loop are executed depending on the condition outside the while before starting the loop.
- If the condition is true then the code inside loop is executed otherwise not.
- Do - While loop: It is a looping procedure in which the statements inside the loop get executed and then the condition at the end of the loop is checked.
- This means even the condition is fails the statements inside the loop are executed once.
- Do while loop name itself suggests that "do the while and then check the condition".
Ithink that the answer is C)
Well thats false. They are only notes, not extra details.
