In this tutorial we discuss and demonstrate the do-while loop. Do While loops are very similar to while loops, except the truth expression is checked at the end of each iteration instead of in the beginning. The main difference from regular while loops is that the first iteration of a do-while loop is guaranteed to run (the truth expression is only checked at the end of the iteration). A Do While Loop will always execute the code in the conditional statement at least one time. We demonstrate this in the examples given in the tutorial.
