<strstream>
Defines several classes that support iostreams operations on sequences stored in an allocated array of char object. Such sequences are easily converted to and from C strings.
For a list of all members of this header, see <strstream> Members.
#include <strstream>
Remarks
Objects of type strstream work with char *, which are C strings. Use <sstream> to work with objects of type basic_string.
참고
The classes in <strstream> are deprecated. Consider using the classes in <sstream> instead.
