Manipulating strings is probably one of your most common tasks. Many developers say it is
also the most error-prone. The Tools.h++ classes RWCString and RWWString give you the
constructors, operators, and member functions you need to create, manipulate, and delete strings
easily.
The member functions of class RWCString read, compare, store, restore, concatenate, prepend,
and append RWCString objects and char*s. Its operators allow access to individual characters,
with or without bounds checking. And the class automatically takes care of memory
management: you never need to create or delete storage for the string's characters.
Class RWWString is similar to RWCString, except that RWWString works with wide
characters. Since the interfaces of the two classes are similar, they can be easily interchanged.
Details of these classes are described in the Class Reference. This section gives you some
general examples of how RWCString works, followed by discussions of selected features of the
string classes.
