Reference
<iostream>

header

<iostream>

Standard Input / Output Streams Library

Header that defines the standard input/output stream objects:

Including this header may automatically include other headers, such as <ios>, <streambuf>, <istream>, <ostream> and/or <iosfwd>.

Including <iostream> automatically includes also <ios>, <streambuf>, <istream>, <ostream> and <iosfwd>.

Note that the iostream class is mainly declared in header <istream>.

Objects

Narrow characters (`char`)

cin: Standard input stream (object)

cout: Standard output stream (object)

cerr: Standard output stream for errors (object)

clog: Standard output stream for logging (object)

Wide characters (`wchar_t`)

wcin: Standard input stream (wide) (object)

wcout: Standard output stream (wide) (object)

wcerr: Standard output stream for errors (wide-oriented) (object)

wclog: Standard output stream for logging (wide) (object)
