std::cin input with spaces?

Question

#include 

std::string input;
std::cin >> input;

The user wants to enter \"Hello World\". But cin fails at the spa

Answer 1

I rather use the following method to get the input:

#include 
#include 

using namespace std;

int main(void) {
    string name;

    cout << "Hello, Input your name please: ";
    getline(cin, name);

    return 0;
}

It's actually super easy to use rather than defining the total length of array for a string which contains a space character.
