String class
String objects are a special type of container, specifically designed to operate with sequences of characters.
Unlike traditional c-strings, which are mere sequences of characters in a memory array, C++ string objects belong to a class with many built-in features to operate with strings in a more intuitive way and with some additional useful features common to C++ containers.
The
string class is an instantiation of the
basic_string class template, defined in
<string> as:
typedef basic_string<char> string;
