Using cout for string

I have a question about the following simple c++ program

#include <iostream>

using namespace std;

int main()
{
	while (cin >> s)
	{
		cout << s << endl;
	}
	return 0;
}	

Open in new window

This program just reads text into a string from the standard input, then outputs it to the screen via std::cout. My question if one enters lots of separate words separated by spaces and terminated by EOF, the program will output each word on a separate line. Why does this happen?

Another thing that is happening in your program is that you are using cin to read from STDIN.  This will read one word at a time not one line.

If you want to read one line you have to use

std::getline(std::cin, s);
