Philosophically do-while should have very rare applications. Because as programmers our code should be as generic as possible. If the code is treating the first iteration as different it is by definition not as generic as possible. This is illustrated by how the example you provided creates a bug when n=1. Linux Torvald's linked list example is a famous one for how a special case is removed: https://github.com/mkirchner/linked-list-good-taste
