  switch(card){
    case 2:
    case 3:
    case 4:

    count += 1;

    count -= 1;
    break;
  }
  
  return count + (count == 0 ? "5 Bet": "Hold");

// Add/remove calls to test your function.
// Note: Only the last will display
cc(2); cc(3); cc(7); cc('K'); cc('A');

  1. You don’t really need to do this count += 0; you can just let the switch break.

  2. You have the string "5 Bet" in your return. You just want " Bet" and " Hold" (note the space in front).

  3. You are not using the correct comparison operator. Try testing the “size” of count against 0.

thank you for your reply, i got 1&2 but can you explain 3 better

Right now you are saying this:

if count is 0
  return count + " Bet"
else
  return count + " Hold"

How would you test the “size” of count against 0? What operator would you use?

if count is **what?** 0
  return count + " Bet"
else
  return count + " Hold"

The test is “If count is equal to zero”. How would you normally test whether something is equal to some other value?
