To answer my own question (in part) from http://www.cplusplus.com/doc/tutorial/dynamic/, the first form deletes memory "allocated for a single element, and the second one for memory allocated for arrays of elements". However, I must say I don't understand why C++ implements new for single quantities and also has a special syntax for deleting those new single quantities. Is there some advantage to using "new" and delete for single quanties compared to just using ordinary automatic variables? I hope someone who understands C++ will enlighten me.
