right

Causes text that is not as wide as the output width to appear in the stream flush with the right margin.

ios_base& right( 
   ios_base& _Str 
);

_Str

A reference to an object of type ios_base, or to a type that inherits from ios_base.

A reference to the object from which _Str is derived.

left also modifies the justification of text.

The manipulator effectively calls _Str.setf(ios_base::right, ios_base::adjustfield), and then returns _Str.

// ios_right.cpp
// compile with: /EHsc
#include <iostream>

int main( ) 
{
   using namespace std;
   double f1= 5.00;
   cout << f1 << endl;
   cout.width( 20 );
   cout << f1 << endl;
   cout.width( 20 );
   cout << left << f1 << endl;
   cout.width( 20 );
   cout << f1 << endl;
   cout.width( 20 );
   cout << right << f1 << endl;
   cout.width( 20 );
   cout << f1 << endl;
}
