how to finish the input?

[asdf]

string text_word;
while (cin>>text_word)
vector1.push_back(text_word);

I just want to input two strings, how to terminate the input ? I press
Enter key, but it didn't terminate input.

The "while" construct is for loops. You don't need a loop in this
program. Why are you using "while"?

Best regards,

This depends on the platform you are using. Under Windows you have press
Ctrl + Z, under Unix Ctrl + D to issue an EOF.

That because newline is just another white space to >>. My
recommendation is to use some sort of counting loop.
void GetStrings(std::vector<std::string&v, int n)
{
std::string s;
char c;

std::cout << "";

for (int i = 0; i < n; i++)
{

std::cin >s;
v.push_back(s);
}

std::cin.get(c); // eats the newline hanging out
}

Yes, he does. He wants to read two words out of one input line.

This sort of answers the OP's question, but a platform-independent
solution is probably better.

I had another reply to your message that I canceled, however it may
show up anyway. This is a more accurate reply.

A loop is one way of doing it, I presented one in another message.
Obviously another way is to have repeated code. That's not the most
efficient way in general, although for two it probably doesn't make
that much difference.
