The right() method of stream manipulators in C++ is used to set the adjustfield format flag for the specified str stream. This flag sets the adjustfield to right. It means that the number in the output will be padded to the field width by inserting fill characters at the start.

Syntax:

ios_base& right (ios_base& str)

Parameters: This method accepts str as a parameter which is the stream for which the format flag is affected.

Return Value: This method returns the stream str with internal format flag set.

Example 1:




// C++ code to demonstrate
// the working of right() function
  
#include <iostream>
  
using namespace std;
  
int main()
{
  
    // Initializing the integer
    double x = -1.23;
  
    cout.precision(5);
  
    // Using right()
    cout << "right flag: ";
  
    cout.width(12);
    cout << right << x << endl;
  
    return 0;
}

Output:

right flag:        -1.23

Example 2:




// C++ code to demonstrate
// the working of right() function
  
#include <iostream>
  
using namespace std;
  
int main()
{
  
    // Initializing the integer
    double x = -1.23;
  
    cout.precision(5);
  
    // Using right()
    cout << "right flag: ";
  
    cout.width(12);
    cout << right << x << endl;
  
    return 0;
}

Output:

right flag:        -1.23
