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]
