title: Why use endl when I can use a newline character?
body: <p>Is there a reason to use <code>endl</code> with <code>cout</code> when I can  just use <code>\n</code>? My C++ book says to use endl, but I don't see why. Is <code>\n</code> not supported as widely as <code>endl</code>, or am I missing something?</p>
