Why should I employ new instead of truthful old malloc()?
A: Constructors/destructors, type safety, overridability.
Constructors/destructors: unlike malloc(sizeof(Fred)), new Fred() calls Fred's constructor. Likewise, delete p calls *p's destructor.Type safety: malloc() returns a void* that isn't type safe. new Fred() returns pointer of right type (a Fred*).
Overridability: new is an operator which can be overridden by a class, whereas malloc() is not overridable on a per-class basis.
