I’m a big fan of starting out simple and building up from there. And it’s harder to get any simpler than a “Hello, World!” application. Even here, if you really think about it, there’s a lot going on. So I decided to annotate this for you. And while doing so, tried to add just a little bit more code than your typical “Hello, World!” application so that you can see a little better how things relate.

For example, the main method actually has multiple forms it can use. Seeing them both together helps to understand the differences. And the same thing with displaying text using cout. I think it helps to understand both displaying text with cout and reading text with cin when you can see both of them used together.
