The C++ strings library includes support for two general types of strings:
- std::basic_string - a templated class designed to manipulate strings of any character type.
- Null-terminated strings - arrays of characters terminated by a special null character.
The templated class std::basic_string generalizes how sequences of characters are manipulated and stored. String creation, manipulation, and destruction are all handled by a convenient set of class methods and related functions.
Several specializations of std::basic_string are provided for commonly-used types:

There are three types of null-terminated strings:
