Is there some overhead involved that takes some processor cycles? Yes. However, we are no longer in the IBM-PC world of 4.77Mhz processors. Using exceptions is a very expedient way of controlling program execution and it is something that is generally easy to maintain in comparison to the extensive extra coding that would be necessary to perform the work without using exceptions.
