#include <bits/stdc++.h>
using namespace std;

int main()
{

// Stream 
stringstream ss; 
ss.clear(ss.eofbit); 

// Using eof() function 
bool isEOF = ss.eof(); 

// print result 
cout << "is stream eof: "
     << isEOF << endl; 

return 0;

EOF signifies End of file , usually used when we are dealing with files in C++, if we are willing to read the entire file, we loop the file using while(!streamobject.eof()){ /code/}

its not a function . IT`s actually ss.eofbit, which signifies the last character of the stream object

EOF signifies end of file, checks if eofbit is set or unset.
eofbit is a flag that is true when the last character of the file is encountered.

proper comments have been added so that u understand the string stream.

A stream is an abstraction that represents a device on which input and ouput operations are performed. A stream can basically be represented as a source or destination of characters of indefinite length.

Constructs a stringstream object

Please read about stringstream in c++ … U`ll find many resources on net
