Question

which is more accurate in giving resulting values,while or do while. explain.

Answer 1

neither is really more accurate than the other. Its more of a matter of when the loop takes place. A while loop checks the condition before the loop, a do while loop executes at least one iteration of the loop and then does the check.

So, if you must ensure the loop is executed at least once, use a do while.

Answer 2

generally while loop is preferred over do while

Answer 3

both have there own properties ... it according to the logic which one you used . both gives the accurate result
