It's from the Accelerated C++
I am puzzled about the "cin",it's said that "it discards any whitespace
characters in the standard input stream, then reads from the standard input
into variable",but why it outputs "Samuel Beckett",not "Samuel" and pause for
next input?

Thank you! *^_^*

"What does the following program do if, when it asks you for input, you type
two names (for example, Samuel Beckett)? Predict the behavior before running
the program, then try it.

#include <iostream>
#include <string>

int main()
{
    std::cout << "What is your name? ";
    std::string name;
    std::cin >> name;
    std::cout << "Hello, " << name
              << std::endl << "And what is yours? ";
    std::cin >> name;
    std::cout << "Hello, " << name
              << "; nice to meet you too!" << std::endl;
    return 0;
}

I'm not sure what your question are, but
std::cin >> xx;
will stop at the first space, if xx is a std::string.

What is left after the space will be stored untill
the >> operator is used again.
