I'm trying to consume the rest of an input on cin. Currently my function does this ...

void foo() {
    // Input "514 G Alex Thornton
    std::cin >> INT >> STD::STRING >> STD::STRING
}

So far the int variable consumes 514, and the first string variable consumes G; however, that leaves the name remaining, which can be an infinite amount of words. Is there a way to consume the rest of the line?

You can use `std::getline ()` to read the rest. – πάντα ῥεῖ Oct 24 '15 at 09:48
How do I do that? I understand using getLine(std::cin, VARIABLE) But I want to split the input to other variables – Jacob Macallan Oct 24 '15 at 09:51
You can do further splitting using `std::istringstream `. – πάντα ῥεῖ Oct 24 '15 at 09:53
@Xari read the `std::cin >> INT >> STD::STRING;` and then further use `getline(std::cin, STD::STRING);` – Ahmed Akhtar Oct 24 '15 at 09:53
My professor at the moment wants me to do without istringstream. And what do you mean Ahmed? Can I see an example? Cause that's what I did but it only consumes one part of the name "Alex" – Jacob Macallan Oct 24 '15 at 09:55
Oh thank you! It hit me while I was writing. Getline will just consume up to the carriage return, right? Therefore getting the entire input. – Jacob Macallan Oct 24 '15 at 10:00
