풀이

#include <iostream>
using namespace std;

int main (int argc, char *argv[])
{
  int a;
  cin >> a;
  while (a < 100 || a > 999)
  {
    cin >> a;
  }
  int b;
  cin >> b;
  while (b < 100 || b > 999)
  {
    cin >> b;
  }

  cout << a * (b % 10) << endl;
  cout << a * (b / 10 % 10) << endl;
  cout << a * (b / 100) << endl;
  cout << a * b << endl;
  return 0;
