(C++) std::setfill
std::setfill is an STL std::iostream manipulator to determine the filling/padding character used by std::setw.
#include <iomanip> #include <iostream> int main() { const int value = 123; std::cout << "12345678\n" << std::setw(8) << value << '\n' << std::setfill('x') << std::setw(8) << value << '\n'; }
Screen output:
12345678 123 xxxxx123
