Exactly: raw use of pointers is dangerous - you either get dangling pointers 
or leaks. And they're more work to use than the containers. They're best 
limited to implementing data structures where performance is paramount.

A container implementation handles memory management and much of the 
alogithms for you. That's easier to write, potentially safer, and may (or 
may) not be similar in performance. Which was the reason for my original 
question.
