title: Premature optimization and Premature pessimization related to C++ coding standards
body: <p>Herb Sutter's <em>C++ coding standards</em> says to avoid <code>Premature optimization</code> and <code>Premature pessimization</code>. But I feel both is doing the same thing. So expecting some help to clarify these two concept with the difference between them. If you come-up with some examples, It will be more benefit for others.
