Why am I getting garbage values?

I'm trying to make some basic number incrementation but I'm getting some weird garbage values. (this works in C# but not in C). Could someone tell me why this is not working?

while (1)
{
      int command = 0;

      printf ("Action: ");
      scanf ("%d", &command);


      int countX, countY, countZ = 0;
      if (command == 1)
    {
      countX++;
    }
      if (command == 2)
    {
      countY++;
    }
      if (command == 3)
    {
      countZ++;
    }
      if (command == 0)
    {
      printf ("x: %d, y: %d, z: %d", countX, countY, countZ);
    }

}
