Simple getline and cin ignoring the first character

Question

I'm trying to get these outputs separated, but the second output's first character is being ignored.

Input:

1

1 2 3

Output:

(space)2 3

Expected output...

1 2 3

#include <iostream>

using namespace std;


int main()
{
    string a; cin >> a;
    string s; cin >> s;
    getline(cin, s);
    cout << s;
}

Answer 1

This program produces the required output

#include <iostream>

using namespace std;

int main()
{
    string a; cin >> a;
    cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
    string s;
    getline(cin, s);
    cout << s;
}

The call to cin.ignore() moves to the next line, as you are still on the previous line after cin >> a; . You could do something like string dummy; getline(cin, dummy); string dummy; getline(cin, dummy); but ignore avoids using an unnecessary variable.
