filling or padding characters in c++
Sets c as the stream’s fill character.
Behaves as if member fill were called with c as argument on the stream on which it is inserted as a manipulator (it can be inserted on output streams).
This manipulator is declared in header <iomanip>.
Example
#include <iostream>
#include <iomanip> //for setfill and setw
int main ()
{
std::cout << std::setfill ('x') << std::setw (10);
std::cout << 9 << std::endl;
getchar();
return 0;
}
Output
xxxxxxxxx9
