public member function

std::ios::fill

<ios>
char fill ( ) const;
char fill ( char fillch );
Get/set the fill character
The first function version returns the fill character.

The second function version sets fillch as the new fill character and returns the fill character previously set.

The fill character is the character used by output insertion functions to fill spaces when padding results to the field width.

The parameterized manipulator setfill can also be used to set the fill character.

Parameters

fillch
the new character to be used as fill character.

Return Value

The value of the fill character before the call.

// using the fill character
#include <iostream>
using namespace std;

int main () {
  char prev;

  cout.width (10);
  cout << 40 << endl;

  prev = cout.fill ('x');
  cout.width (10);
  cout << 40 << endl;

  cout.fill(prev);

  return 0;
}


The output of this example is something similar to: 
        40
xxxxxxxx40
