[CentOS] [OT] bash here documents

Suppose I have this C++ program:
#include <iostream>
int main (int argc, char** argv)
    while (1)
        char cmd[80];
        std::cin.getline(cmd, 80);
        std::cout << "response to " << cmd << std::endl;

compiled by: c++ -o junk junk.cpp

and I have this bash script:
./junk <<EOF
echo "Something else"

When I run the script, the program starts and waits for input forever.
I have 2 questions:
1) The "blah" and "bleh" line are not echoed to cout. Why not? Does the here document not send the data to stdin?
2) How do I terminate the program? When run interactively, I use <ctrl>-C.
