How exactly can I make a program which will display the digits of a number?

[Cplusminusplus]

The number can be literally any number, lets say it is 1425. The program needs to print out:
"1 4 2 5"
Is this possible with a while loop?

#include <iostream>
#include <sstream>

int main()
{
  int someNumber = 1425;
  std::stringstream stream;
  stream << someNumber;

  char singleChar;
  while (stream >> singleChar && std::cout << singleChar << " ");
}
