title: What happens in memory when a C++ class is instantiated
body: <p>I'm interested in the nuts and boltw of C++ and I wondered what actually changes when an object is instantiated. I'm particularly interested if the functions are then added to memory, if they are there from runtime or if they are never stored in memory at all. </p>
  
  <p>If anyone could direct me to a good site on some of the core bolts of C and C++, I'd love that too.</p>
  
  <p>Thanks,
  Jo </p>
