When is a do-while appropriate?

Question

When is a do-while the better choice over other types of loops? What are some common scenarios where its better than others?

I understand the function of a do-while,

Answer 1

I usually use a do-while when something needs to happen, but it won't necessarily happen "correctly" on the first time. For instance:

int x;
do
{
    x = random.next(100);
    cout << x << endl;
} while (x != 13);

In this case, the x you start with doesn't matter at all, because it's overwritten.
