Can I Get a Word In - 22 Mar 2008 08:00 GMT

I have a hex value, 0x14000, and I want to output it as, 0x00014000. Is
it possible to get this output using std::cout?
Thanks

#include <iostream>
using namespace std;
int main(int argc, const char* argv[])
{
cout << "0x";
cout.flags(ios::hex);
cout.width(8);
cout.fill('0');
cout << 0x14000 << "\n";
return 0;
}

That works, but I prefer to use io manipulators:

#include <iostream>
#include <iomanip>
using std::cout;
using std::setw;
using std::setfill;
using std::ios;
using std::hex;
using std::dec;

int main(int argc, char * const argv[]) {

cout << " 0x" << setw(8) << setfill('0') << hex << 0x14000 << "\n" << dec << 123 << "\n";

return 0;
}

Certainly a more elegant solution, but I figured the question was basic
enough that it kind of warranted the most explicit/obvious possible
answer. I've found manipulators confuse people completely new to the
language more than they help right up front.

Thanks for the reply. I'm actually comfortable using manipulators, it
just wasn't immediately obvious how to use them to get the output I wanted.
