Last output missing when copying input with multiple lines.

Hello,
When you copy this whole input:
test1
test2
test3

and paste it into the running program below why do you get the output:
test1 test2

instead of:
test1 test2 test3

Moreover, what adjustment in the code can you make to get the latter output?

#include <iostream>
#include <string>

using namespace std;

int main()
{
    string line{};
    while(cin >> line)
    {
        cout << line << ' ';
    }
}

Try appending << std::flush; or << std::endl; for explicit flushing.

What is the medium through which you are running this program? I thought blocking on cin was automatically supposed to flush, but I could be mistaken.

Note that it'll only actually send the last line automatically if it ends with a newline, assuming you're using a normal terminal/console.

How are you terminating the while loop? With Windows as an example I get with the input each on a separate line:

test1
test1 test2
test2 test3
test3 ^Z

Or having all the input on one line:

test1 test2 test3
test1 test2 test3 ^Z
