title: Does try-catch block decrease performance
body: <p>This <a href="http://www.cplusplus.com/doc/tutorial/exceptions/" rel="noreferrer">link</a> states,</p>
  
  <blockquote>
    <p>To catch exceptions we must place a portion of code under exception
    inspection. This is done by enclosing that portion of code in a try
    block. When an exceptional circumstance arises within that block, an
    exception is thrown that transfers the control to the exception
    handler. If no exception is thrown, the code continues normally and
    all handlers are ignored.</p>

  <p>Does it mean that having a try block reduces performance due to the extra task of "inspection" during run time?</p>
