Now that you've seen the power of functions
0:01
both for re-using code allowing you to work on it
0:04
in one place but affect it in many places that it's used
0:07
in your program and treated as a black box.
0:11
Just, here's a core idea that may be complicated but
0:14
all you got to think about is what goes in
0:16
and what comes out, for example, check for winning throw.
0:18
That was super complicated, but we just passed in the plays
0:22
and got the winner back.
0:23
That was nice so let us think about our program
0:26
in a much higher level.
0:28
So, I put together some practice exercises
0:30
for this chapter, as well.
0:31
I think you'll have a lot of fun wit this one.
0:33
A pair of core concepts that are very close to each other
0:36
and that's just about creating functions.
0:37
Here's a function that takes a parameter and uses it.
0:41
Here's a function that has a return value
0:44
it gets the data internally creates it
0:46
and then gives it back.
0:47
And we can even use these together
0:49
like we can use the get name one to actually get the name
0:51
and then to say hello to greet the person after they've
0:54
given us their name.
0:55
So, here's a couple ways in which we can do that.
0:58
For this exercise, your job is to take
1:00
the M&M guessing game which you'll recall
1:03
it was written with no functions
1:05
just all jammed together created back in CH05
1:08
before we talked about functions.
1:10
And clean it up, using functions.
1:12
Now, if you look in this folder
1:14
in practices, CH06.
1:16
You can see there's a copy this.
1:17
I put it here just to make sure that it's right here
1:20
and easy to get to.
1:22
If you go here, you can see
1:23
it's doing things like printing out what the game is
1:25
some information.
1:27
Getting some random details.
1:29
Playing some rounds, checking for a winner.
1:32
These should all sound kind of familiar.
1:34
And you could use functions to make it a lot nicer.
1:36
So, that's your job, take this code
1:38
make a copy of it somewhere
1:40
make it better with functions.
