C++ Tip: Aware of the confusion between delete with delete[]

A good exercise to aid in always using delete [] where appropriate is to code your own autoarray_ptr<class T> following the pattern of c++ auto_ptr. The destructor calls delete [] when the instance goes out of scope. Saves writing a lot of messy delete [] code in "if chains" and switch blocks. Stroustrup didn't include it in C++ Programming Language since he assumed once you had auto_ptr it was just boiler plate to code your own class for autoarray_ptr.
