[C++] HackerRank Day1 Solution

*You have to use 'getline(cin, string)' to get a whole line. (not 'cin >> string')
However, you've already used 'cin' on the previous line. 'cin' left '\n' in the buffer, so your next 'getline' would get just a '\n'.
so use
getline(cin>>ws, string)
to consume the whitespace or newline.

*To express fixed point,
 cout << fixed << setprecision(1);

    // Declare second integer, double, and String variables.
    int ii;
    double dd;
    string ss;
    // Read and save an integer, double, and String to your variables.
    cin >> ii;
    cin >> dd;
    getline(cin >> ws, ss);
    // Note: If you have trouble reading the entire string, please go back and review the Tutorial closely.
 
    // Print the sum of both integer variables on a new line.
    cout << ii + i << endl;
    // Print the sum of the double variables on a new line.
    cout << fixed << setprecision(1);
    cout << dd + d << endl;

    // Concatenate and print the String variables on a new line
    cout << s + ss << endl;

    // The 's' variable above should be printed first.
