C++ Library - <basic_stringstream>
Introduction
It is a stream class to operate on strings.bjects of this class use a string buffer that contains a sequence of characters. This sequence of characters can be accessed directly as a basic_string object, using member str.
Definition
Below is definition of std::basic_stringstream.
template < class charT,
class traits = char_traits<charT>,
class Alloc = allocator<charT>
> class basic_stringstream;
Parameters
charT − Character type.
traits − Character traits class that defines essential properties of the characters used by stream objects.
int_type − Integer Type.
pos_type − Traints Pos Type.
off_type − Traints Off Type.
allocator_type − Allocator.
