How to use filtering streams with cin?

16 Nov 2011

      Hello All,

I have trouble in using filtering streams with cin in the following code:

#include 
#include <iostream>

namespace io = boost::iostreams;

int main()
{
    io::filtering_istream in;
    in.push(std::cin);

    int i;
    in >> i;
    std::cout << i << '\n';
    in >> i;
    std::cout << i << '\n';
}

I have to input two integers and ctrl+z to terminate the input from screen.
How can I input 1 integer, output it, then input another one and output it,
which like the conventional std::cin?

Thank you very much for your kind help!

Best regards,

Jayden
