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?

Hi Jayden, It sounds like filtering_istream, in, is buffering its input. Is there some filtering_istream option for unbuffered input? If so, try that. HTH, -Larry
