I got this new book to help teach C++ and it's been going great, absolutly flying through it and no probs with understanding it, till today :S

I'm up to a part in this book that talks about exception errors or handling, from what i gather you use the code in places you think will have errors :S no really i don't have a clue, well atleast i should be treated this way and if someone could just help me wrap my head around it that would be awsome
