00:00:13,820 --> 00:00:19,880
Hello and welcome to the go like programming language course in the previous session, we talked about

2
00:00:19,880 --> 00:00:25,820
create a simple function in this session, we want to talk about the other functions concept.

3
00:00:29,590 --> 00:00:31,630
Function with parameters.

4
00:00:33,550 --> 00:00:40,570
Parameters are specified within the pain of plant disease in the function definition separated by commas

5
00:00:40,930 --> 00:00:48,160
when we call the function, we supply the values in the saying they are parameter is just like a variable.

6
00:00:48,520 --> 00:00:56,620
Parameters are specified after the function name inside the plant is this you can add as many parameters

7
00:00:56,620 --> 00:00:59,050
as you want inside the function.

8
00:00:59,680 --> 00:01:01,990
Now you can see the syntax.

9
00:01:04,200 --> 00:01:09,750
Go to the school program and illustrate how to use function parameters.

10
00:01:11,890 --> 00:01:20,250
First, creating it function, the two parameters of each time that adds together, for example,

11
00:01:22,900 --> 00:01:25,630
forage at

12
00:01:28,060 --> 00:01:37,080
each type of it, is it and why type of it is it?

13
00:01:40,180 --> 00:01:51,520
Now define a variable named total debt as towards sum of two variables total time Colin equals x plus

14
00:01:51,820 --> 00:01:52,360
y.

15
00:01:53,050 --> 00:01:56,190
Now display the value of total variable.

16
00:01:57,130 --> 00:02:11,620
Refer to the title of X plus y equals person D lowercase and sets the variable total.

17
00:02:13,920 --> 00:02:16,860
Reformat the code and save the project.

18
00:02:17,850 --> 00:02:29,400
Now go to the main function and in walked and function at and set to end values as arguments inside

19
00:02:29,400 --> 00:02:29,880
it.

20
00:02:30,120 --> 00:02:33,810
For example, 20 and 30.

21
00:02:35,120 --> 00:02:39,920
Now reformat the code, save the project and execute the program.

22
00:02:43,620 --> 00:02:45,570
Now we can see the output.

23
00:02:46,170 --> 00:02:53,100
We could define the function named at that axis to enter value as parameters and sum them together and

24
00:02:53,100 --> 00:02:54,480
display the result of it.

25
00:02:55,380 --> 00:03:02,430
Important note if definitions with names that is sought in an uppercase letter will be exported to other

26
00:03:02,430 --> 00:03:03,120
packages.

27
00:03:03,630 --> 00:03:10,050
If the function name starts with the lowercase letter, it won't be exported to other packages, but

28
00:03:10,050 --> 00:03:16,170
you can call this function within the same package in order not to prolong the time of decision.

29
00:03:16,380 --> 00:03:20,100
We will finish finished and we will continue the content in the next session.

30
00:03:20,400 --> 00:03:20,940
Goodbye.
