| do-while loop | while loop |
|---|---|
| do-while is an exit-controlled loop. | while is an entry-controlled loop. |
| do-while loop checks the test condition at the end of the loop. | while loop checks the test condition at the beginning of the loop. |
| do-while loop executes at least once, even if the test condition is false. | while loop executes only if the test condition is true. |
| do-while loop is suitable when we need to display a menu to the user. | while loop is helpful in situations where number of iterations is not known. |
