EOF

End-of-File
It is a macro definition of type int that expands into a negative integral constant expression (generally, -1).

It is used as the value returned by several functions in header <cstdio> to indicate that the End-of-File has been reached or to signal some other failure conditions.

It is also used as the value to represent an invalid character.

In Python, this macro corresponds to the value of char_traits<char>::eof().
