basic_ios::fill

Specifies or returns the character that will be used when the text is not as wide as the stream.

char_type fill( ) const;
char_type fill(
   char_type _Char
);

Parameters

  • _Char
    The character you want as the fill character.

Return Value

The current fill character.

Remarks

The first member function returns the stored fill character. The second member function stores _Char in the fill character and returns its previous stored value.

// compile with: /EHsc
#include <iostream>
#include <iomanip>

int main( ) 
{
   using namespace std;

   cout << setw( 5 ) << 'a' << endl;
