c++ when will while(cin>>s) stop

Question

I\'m new to C++. I\'m sorry if this question is duplicated but I just can\'t find similar question.

very basic code:

string s;
while (cin >> s)

You can signal EOF via CTRL-D or CTRL-Z.

Or, you can check for a particular string to break the loop, like below:

string s;
while (cin >> s)
  {
     if(s == "end")
          break;
     cout << s << endl;
  }
