 So in the time-honored tradition of learning how to program we developed something known as high low a number guessing game And that's actually why we talked about math dot random just a second ago is because we can now Sort of pile in all these basic structures that we've talked about loops conditionals math dot random Getting a user's input and we can now play this simple game, which is simple enough. You know, uh, I Say guess a number Go ahead guess a number Between zero and 100 higher higher lower Lower higher Lower You got it now you see what we can do is we build that design out So suddenly instead of it being me telling you and you know, maybe Whatever I was lying the entire time, but what we're doing is we're generating that random Number and so now what we do is we get our input from the user We're getting this now this guess we call this something known as my sentinel value and We call that sentinel value because what we're doing is that's going to control my loop if we take a look You know as I see that I only want to really tell my user if they are too high or too low If they did not guess the correct number and Then in turn if they didn't guess the correct number I do a little bit of a conditional statement here where I tell them whether or not they were too high or too low And I have to determine that on my end as well Well, once I've done all of this once I've done this kind of determining I have to get a New guess the reason why is because if I don't get a new guess from the user as I go back up to the top of my loop I Re-evaluate the conditional statement again. I did not change Guess because I didn't do this bottom portion I'm going to run into an infinite loop where it says too high or too low because I never Changed my sentinel value and that's one of the main things with a loop is we have to change that value Otherwise we get stuck in the infinite loop In our case what we do is at the end we at least prompt the user We prompt the user one more time So that we at least are changing it each time if that makes any sense
