getline() reads input until the newline character and cin>> fails to remove the newline character after reading input. By calling getline() after cin>>, you're essentially just grabbing the newline character (and any white space) that cin>> left behind.

You can use getline() to get the number as well (just have to take an extra step to interpret as number).

This is what I have and it works perfectly -

using namespace std;
string str;
getline(cin, str);
cout << str << endl;
