Strings 5

Manipulating strings is one of the most common and error prone tasks that a

programmer does. It's a perfect opportunity for C++ to show its advantages.

Class

RWCString

has many powerful string processing features that are just as

efﬁcient as C, but far less prone to errors. For example, the class automatically

takes care of memory management. It's just about impossible to delete

something twice or not delete it at all.

Class RWWString offers support for wide character strings. These are strings of

type

wchar_t

which, in general, may consist of more than one byte. The

interface of

RWWString

is extremely similar to

RWCString

, allowing them to

be interchanged easily.

5.1 Example

Here is a short example that exercises the

RWCString

class:
