CPP how to format strings to align to the right side

Question

I am looking for a simple CPP solution to align a string to the right size.

What do I mean by this? here is an example:

the normal output would be

hello [message]
foo [message]

I would like it to output like this:

 hello [message]
   foo [message]

note: this is not for aligning a table but rather to know how to align a message by adding certain spaces to the left (or smth).

What do your text-books, tutorials or class-notes say about *I/O manipulators* like `std::setw` and `std::right`? — Some programmer dude, Sep 13 '22 at 09:24

In the library, you can find std:right and std:setw which can help to justify O/P to the right.

If 'i' is your string, then below is a snippet that you can use :-

#include <iomanip>

cout << right
     << setw(20)
     << fixed
     << i << endl;

This works for me but how could I append a message to the end of "I"? – Maubg Sep 13 '22 at 09:35
Yeah just do <<"Hello "<<"message" – 10may Sep 13 '22 at 09:38
I don't understand the right and fixed part tho, without them, It still worked – Maubg Sep 13 '22 at 09:46

Like this ?

#include <iostream>
#include <iomanip>

int main()
{
    std::cout << std::setw(10) << "Hello" << " [message]" << std::endl ;
    std::cout << std::setw(10) << "foo" << " [message]" << std::endl ;
}

Thanks a lot! I just have a question, It looks like when I try to add ANSI colors, the formatting gets messed up. How could I fix this? – Maubg Sep 13 '22 at 09:39
here is what my statement looks like: `std::cout << std::setw(10) << GREEN << topic << RESET << message << std::endl` – Maubg Sep 13 '22 at 09:40
nvm, I fixed it. – Maubg Sep 13 '22 at 09:45
Color in console applications is non-standard and depends on the operating system. – CGi03 Sep 13 '22 at 11:19
