In <\/span>Part 3<\/span><\/a> of my video lecture series exploring the Standard Template Library’s implementation, I explain how our powerful correctness checks in debug mode work.  In VC10, they’re controlled by the macro _ITERATOR_DEBUG_LEVEL, which supersedes VC8 and VC9’s more confusing _SECURE_SCL and _HAS_ITERATOR_DEBUGGING macros.  Additionally, VC10’s #pragma detect_mismatch allows the linker to detect badness that previously would have caused incomprehensible crashes.  Finally, I demonstrate the undocumented and unsupported but exceedingly awesome compiler option \/d1reportSingleClassLayout which prints an ASCII art diagram of a class’s representation.<\/p>\n

This advanced series assumes that you’re familiar with C++ and the STL’s interface, but not the STL’s implementation.  If you haven’t used the STL extensively yet, I recommend watching my introductory series.  For reference, here are all of the links:<\/span><\/p>\n
