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.
