1
00:00:00,267 --> 00:00:03,369
Now that we know how to
make methods return values,

2
00:00:03,369 --> 00:00:06,182
let's go back to our cat
food store program and

3
00:00:06,182 --> 00:00:10,023
update the ask method to return
the string that the user types.

4
00:00:10,023 --> 00:00:14,518
So I'm gonna go to our definition up here
and I'm going to change its return type

5
00:00:14,518 --> 00:00:17,954
from void, that is returning nothing,
to a type of string.

6
00:00:17,954 --> 00:00:22,568
It will return a string value.

7
00:00:22,568 --> 00:00:27,130
And instead of assigning the returned
value of Console.ReadLine to the answer

8
00:00:27,130 --> 00:00:31,907
variable and printing it out, I'm just
going to return that to the main function.

9
00:00:31,907 --> 00:00:36,035
So I'll get rid of the answer variable and
I'll get rid of the called

10
00:00:36,035 --> 00:00:41,472
Console.WriteLine, and I'll just take
the value returned from Console.ReadLine,

11
00:00:41,472 --> 00:00:44,463
and I will return that to
whatever called asked.

12
00:00:44,463 --> 00:00:47,018
In this case, it's the main method.

13
00:00:47,018 --> 00:00:48,402
So let me save that.

14
00:00:50,332 --> 00:00:54,608
And then we can get rid of our
attempt to access the answer variable,

15
00:00:54,608 --> 00:00:57,845
which doesn't exist down
here in the main method.

16
00:00:57,845 --> 00:01:02,021
Instead we're going to take our new
return value from the call to ask and

17
00:01:02,021 --> 00:01:05,022
we're gonna assign it to
a variable called entry.

18
00:01:07,254 --> 00:01:11,568
And again the return value
of Ask is string, so

19
00:01:11,568 --> 00:01:16,661
the type of our entry variable
needs also to be string.

20
00:01:16,661 --> 00:01:20,792
And then we'll just print out the value
that our entry variable contains for now.

21
00:01:20,792 --> 00:01:26,866
Let me try running this, dotnet run.

22
00:01:26,866 --> 00:01:27,763
And as before,

23
00:01:27,763 --> 00:01:31,566
it'll print out the question that
gets passed in the call to ask.

24
00:01:31,566 --> 00:01:33,234
How many cans are you ordering?

25
00:01:33,234 --> 00:01:37,656
And then the call to Console.ReadLine,
we'll wait for our answer, so

26
00:01:37,656 --> 00:01:39,335
we'll say ten cans again.

27
00:01:39,335 --> 00:01:43,981
Hit Enter, the value we typed gets
returned from the call Console.ReadLine

28
00:01:43,981 --> 00:01:46,982
which then gets returned
from the ask method, and

29
00:01:46,982 --> 00:01:49,644
gets assigned to this entry variable here.

30
00:01:49,644 --> 00:01:53,170
And then we print the value of
entry out down here in main, and

31
00:01:53,170 --> 00:01:55,115
there's our printed value ten.

32
00:01:55,115 --> 00:01:58,518
Right now the user types their answer
on a separate line from the question.

33
00:01:58,518 --> 00:02:03,442
That's because we print the question using
Console.WriteLine which prints a string

34
00:02:03,442 --> 00:02:05,272
and then skips to the next line.

35
00:02:05,272 --> 00:02:08,744
It might look a little neater if the type
to answer appeared on the same line as

36
00:02:08,744 --> 00:02:09,459
the question.

37
00:02:09,459 --> 00:02:14,150
We can do this with the Console.Write
method, which prints the string and

38
00:02:14,150 --> 00:02:15,944
then stays on the same line.

39
00:02:15,944 --> 00:02:19,914
So let me update this and
try running it again.

40
00:02:19,914 --> 00:02:24,199
I'll just hit the up arrow to bring up
our dotnet run command and hit Enter.

41
00:02:24,199 --> 00:02:25,944
And you can see that our cursor for

42
00:02:25,944 --> 00:02:29,063
typing our response is now on
the same line as the question.

43
00:02:29,063 --> 00:02:33,534
So I'll say ten cans, and
everything else works the same as before.

44
00:02:33,534 --> 00:02:36,594
We've completed the second feature for
our program.

45
00:02:36,594 --> 00:02:40,728
We asked the user for quantity of cans
they want, call the Console.ReadLine

46
00:02:40,728 --> 00:02:44,942
method to get their keyboard entry, and
store the return value in a variable.

47
00:02:44,942 --> 00:02:48,346
Learning the call methods was the key for
getting this far in your program.

48
00:02:48,346 --> 00:02:51,742
Practicing your new skills is
important to making them stick, so

49
00:02:51,742 --> 00:02:55,710
be sure to check the teacher's notes
on this video for some practice ideas.

50
00:02:55,710 --> 00:02:58,445
You're off to a great start learning C#.

51
00:02:58,445 --> 00:03:01,605
You've learned to call methods and
to use their return values.

52
00:03:01,605 --> 00:03:05,058
Those skills will be useful in
pretty every program you write.

53
00:03:05,058 --> 00:03:07,069
You've even learned to
write your own methods.

54
00:03:07,069 --> 00:03:09,765
There's just one minor
issue with the program.

55
00:03:09,765 --> 00:03:12,356
When we ask the user how
many cans they want to buy,

56
00:03:12,356 --> 00:03:16,328
our question runs right up against
the place their keyboard input is shown.

57
00:03:16,328 --> 00:03:18,718
That looks a little
less than professional.

58
00:03:18,718 --> 00:03:22,210
To fix this, we're going to need
to learn more about strings.

59
00:03:22,210 --> 00:03:27,063
Just like most other programming
languages, C# uses strings to store text.

60
00:03:27,063 --> 00:03:29,052
We'll learn all about
them in the next stage.

61
00:03:29,052 --> 00:03:29,940
See you there.
