I am trying to understand pointers. Is a smart pointer the same an an auto_ptr minus the wrapper http://ootips.org/yonat/4dev/smart-pointers.html Dangling pointers. A common pitfall of regular pointers is the dangling pointer: a pointer that points to an object that is already deleted. how can it point to something that has been deleted

The windows API is big, you have to know how to use them to use libc, etc etc. It's not something you can avoid, even with smart pointers, as most functions won't accept those.

I haven't been using c/c++ for very long. It's mainly thanks to chris that I use pointers. I had a fobia, but after endless code editing sessions I finally get it. It's not an easy thing to learn, but it makes life so much easier, whether your using c++ or c. I use c more often than not, so I don't have all the OOP ideas, c tends to be more straight forward and easier for me to understand personally.

It was a necessity because of the slow processor/memory of the time. Think 'direct screen writing' on the old DOS pc's. It's one of the reasons I preach kids to learn 'C' before they learn C++ or Java or C# or VB.NET. These languages breed sloppy, lazy coding (sorry if I offend anyone, but I've got enough years experience now to know that that is a true statement). Part of that is the OOP paradigm we all try to strive for today. It IS a good thing. I agree. The design of systems using OOP techniques is better, easier. But coding should still be second nature to young, up and coming geeks before we teach them design patterns... sorry, having a sloppy code day myself.... POINTERS RULE!!!!
