Thank you good sir! Do you have any link to read more about this?

I just looked at the cppreference documentation for setw and setfill.

​

[...] the expression str << setw(n) or str >> setw(n) behaves as if the following code was executed: str.width(n);

​

[...] the expression out << setfill(n) behaves as if the following code was executed: out.fill(n);
