NAME

std::setfill - std::setfill

Synopsis

Defined in header <iomanip>
template< class CharT >
/*unspecified*/ setfill( CharT c );

When used in an expression out << setfill(c) sets the fill character of the stream
out to c.

Parameters

c - new value for the fill character

Return value

Returns an object of unspecified type such that if out is the name of an output
stream of type std::basic_ostream<CharT, Traits>, then the expression out <<
setfill(n) behaves as if the following code was executed:

out.fill(n);

Notes

The current fill character may be obtained with std::ostream::fill.

Example

// Run this code

#include <iostream>
#include <iomanip>
int main()
{
std::cout << "default fill: [" << std::setw(10) << 42 << "]\n"
<< "setfill('*'): [" << std::setfill('*')
<< std::setw(10) << 42 << "]\n";
}

Output:

default fill: [ 42]
setfill('*'): [********42]
