Sets the adjustfield format flag for the str stream to right.
When adjustfield is set to right, the output is padded to the field width (width) by inserting fill characters (fill) at the beginning, effectively adjusting the field to the right.
The adjustfield format flag can take any of the following values (each with its own manipulator):
For standard streams, the adjustfield flag is set to this value (right) on initialization.

Adjust output to the right
When adjustfield is set to right, the output is padded to the field width (width) by inserting fill characters (fill) at the beginning, effectively adjusting the field to the right.
The adjustfield format flag can take any of the following values (each with its own manipulator):
| flag value | effect when set |
|---|---|
| internal | the output is padded to the field width by inserting fill characters at a specified internal point. |
| left | the output is padded to the field width appending fill characters at the end. |
| right | the output is padded to the field width by inserting fill characters at the beginning. |
For standard streams, the adjustfield flag is set to this value (right) on initialization.
Parameters
- str
- Stream object whose adjustfield format flag is affected.
Because this function is a manipulator, it is designed to be used alone with no arguments in conjunction with the insertion (<<) and extraction (>>) operations on streams (see example below).
Return Value
Argument str.Example

Output:
- 77 -77 -77 |
Data races
Modifies str. Concurrent access to the same stream object may cause data races.Exception safety
Basic guarantee: if an exception is thrown, str is in a valid state.See also
