object
std::cerr
<iostream>
Standard output stream for errors
cerr is an object of class
ostream that represents the standard error stream. It is associated with the
cstdio stream
stderr.
By default, most systems have their standard error output set to the console, where text messages are shown, although this can generally be redirected.
Because
cerr is an object of class
ostream, we can write characters to it either as formatted data using for example the insertion operator (
ostream::operator<<) or as unformatted data using the
write member function, among others (see
ostream).
