How to Align text to the right using cout?

Question

Suppose I have a string s which is given below:

string s="i am\ngoing\nto\ncuet";

I want to align the string to the right during display in console. So I want to show output like this:

EDIT: rightmost characters should be aligned.

                                      i am
                                     going
                                        to
                                      cuet

I tried this code to show the output:

cout.width(75);
cout<<s;

But it only right align the first line like this:

                                                         i am
going
to
cuet

Then I tried this code to get the output:

for(int i=0 ; i<s.size(); i++)
    {
        cout.width(75);
        cout<<s[i];
    }

But I get peculiar output using this code:

                                                                  i

                                                        a
                                                   m

                                                                  g
                                                             o
                                                        i
                                                   n
                                              g

                                                                  t
                                                             o

                                                                  c
                                                             u
                                                        e
                                                   t

How can I get the desired output?

You need to read s line by line, then output each line right aligned.

#include <iostream>
#include <iomanip>
#include <sstream>

void printRightAlignedLines(const std::string& s, int width)
{
    std::istringstream iss(s); //Create an input string stream from s
    for (std::string line; std::getline(iss, line); ) //then use it like cin
        std::cout << std::setw(width) << line << '\n';
}

int main()
{
    std::string s = "i am\ngoing\nto\ncuet";
    printRightAlignedLines(s, 75);
}
