 Here's part of a program that asks a user for a quantity of items to order and the unit price and then calculates the total price for the order. In the preceding video, I told you to omit the backslash N at the end of the prompt and to leave a space at the end instead. What happens if you don't do that? Let's try it and find out. Let's put in a backslash N, rebuild and execute the program. See how the input is disconnected from the prompt? It just doesn't look right. Now let's get rid of the backslash N and also get rid of the space at the end. Let's rebuild and compile and you'll notice that the cursor is too close to the colon. Again, it just doesn't feel right. Adding that extra space gives us something that looks right and feels right. There is one case where putting in that extra space at the end of the prompt does not help. Let's put up the prompt for the unit price and put a dollar sign there and the extra space and then we'll scan a double into the price variable. We'll enter the quantity and now when we enter this price, having that extra space again just doesn't feel right. So in this particular instance, I'm going to get rid of that trailing space and rebuild. Now everything looks right and feels right. In general, you should follow the guidelines to never put in a new line at the end of the prompt but to use a space instead. As you write more programs, you'll get a feel for those few instances when the extra space isn't the better choice.
