00:00:13,090 --> 00:00:17,920
Hello and welcome to the golden programming language course in this session.

2
00:00:17,950 --> 00:00:20,560
We want to talk about operators concept.

3
00:00:26,220 --> 00:00:34,890
Go Lang, operators and operator is a symbol that tells the compiler to perform certain actions, does

4
00:00:35,040 --> 00:00:40,530
the functionality of the gold language is incomplete without the use of operators?

5
00:00:41,100 --> 00:00:50,100
Operators allow us to perform different kinds of operations on options in go language.

6
00:00:50,490 --> 00:01:01,080
Operators can be categorized based upon their different functionality or its metric operators, assignment

7
00:01:01,080 --> 00:01:07,020
operators, relational operators, logical operators.

8
00:01:08,210 --> 00:01:15,350
And Bitwise operators, now we are going to talk about operators separated.

9
00:01:21,100 --> 00:01:28,570
Artists, network operators, the artists, music operators are used to perform common arithmetic on

10
00:01:28,570 --> 00:01:37,120
operations such as addition, subtraction, multiplication and etc. following table shows, all the

11
00:01:37,120 --> 00:01:47,500
arithmetic operators supported by Go Language Addition adds to operations subtraction subtracts second

12
00:01:47,500 --> 00:01:51,700
operations from the first multiplication multiply.

13
00:01:51,730 --> 00:01:57,700
Both operations division divides the numerator by the denominator.

14
00:01:58,330 --> 00:02:06,310
Modulus gives the remainder after an integer division increment, it increases the integer value one

15
00:02:06,310 --> 00:02:08,620
by one and decrement.

16
00:02:08,860 --> 00:02:12,250
It decreases the integer value one by one.

17
00:02:12,850 --> 00:02:17,830
Now let's go to your school to get on to display the use of arithmetic operators.

18
00:02:19,420 --> 00:02:31,450
First, go to the Project Explorer and define a folder named like operators and create a fine inside

19
00:02:31,450 --> 00:02:33,550
it like name.

20
00:02:33,940 --> 00:02:42,880
That could set a package name like Package Main and define the main function.

21
00:02:43,060 --> 00:02:55,480
Following may first be defined to variable, such as a column equals 50 and bee colony equals 30.

22
00:02:57,430 --> 00:03:05,500
We want to give an example of an addition, so define the variable life result and poor sum of two area,

23
00:03:05,500 --> 00:03:08,050
both A and B into it.

24
00:03:08,470 --> 00:03:10,660
So define a variable like resolved.

25
00:03:11,830 --> 00:03:25,990
One column equals a plus b addition operator adds two operands in this case addition A and B now write

26
00:03:25,990 --> 00:03:28,420
the following code to display an output.

27
00:03:28,450 --> 00:03:30,130
So we write it if.

28
00:03:32,780 --> 00:03:33,680
Edition

29
00:03:35,870 --> 00:03:56,600
results of a plus B equals per cent D and sit back air and put resolve to reform at the court, save

30
00:03:56,600 --> 00:04:04,070
the project and execute the program, go to a terminal first, go to a project folder, see the operator's

31
00:04:06,310 --> 00:04:10,520
Clearstream and run the program by the comment go round.

32
00:04:10,550 --> 00:04:15,110
Does this mean that go now?

33
00:04:15,110 --> 00:04:21,090
We can see the output addition result of a plus B equals eight.

34
00:04:22,280 --> 00:04:30,290
The sum of two values A and B was added to the result one variable and its value is equal to a T and

35
00:04:30,290 --> 00:04:36,800
they could use from addition operant and other GS subtraction.

36
00:04:37,700 --> 00:04:45,500
Now we want to give an example of a subtraction, so define a variable like resolve to insult like the

37
00:04:45,500 --> 00:04:48,320
two values A and B into it.

38
00:04:48,590 --> 00:04:51,140
So three years the last court.

39
00:04:53,390 --> 00:05:06,470
So define the value of a light resolved to call them equals a minus B cell transaction operator or subtracts

40
00:05:06,470 --> 00:05:09,050
second print from the first or print.

41
00:05:09,350 --> 00:05:15,290
In this case, subtract A and B now write funny and call to display an output.

42
00:05:15,290 --> 00:05:16,760
So we write F f.

43
00:05:20,410 --> 00:05:41,620
Some traction result of a minus B equals person B and C, it resolved to reformat the code, save the

44
00:05:41,620 --> 00:05:50,890
project and execute the program first clear screen and run the command to run dot spec as this may not

45
00:05:50,890 --> 00:05:51,190
go.

46
00:05:53,100 --> 00:05:59,430
Now we can see the outward subtraction, a result of a minus B equals 20.

47
00:05:59,760 --> 00:06:06,900
Subtract the two values A and B into the horizontal variable and its value is equal to 20.

48
00:06:07,320 --> 00:06:13,380
And we could use from subtraction operate another trace multiplication.

49
00:06:14,130 --> 00:06:16,950
Now we want to give an example of a multiplication.

50
00:06:17,880 --> 00:06:21,230
So define a variable like of three and multiplication.

51
00:06:21,300 --> 00:06:24,480
The two one is A and B into it.

52
00:06:26,120 --> 00:06:38,180
So two years the last quote defined a variable like result, three column equals a multiplication,

53
00:06:38,630 --> 00:06:48,440
b multiplication operate or multiplication, two options in this case, multiplication A and B now write

54
00:06:48,440 --> 00:06:51,350
following code to display an output at her.

55
00:06:52,780 --> 00:06:55,570
Multi allegation.

56
00:06:57,430 --> 00:07:08,680
Resolve of a multiple decades, B equals Person D, and is it resolved?

57
00:07:08,860 --> 00:07:09,370
Three.

58
00:07:10,450 --> 00:07:13,980
The format the court saved the project and execute the program.

59
00:07:16,950 --> 00:07:24,390
Now we can see the output multiplication result of A and B equals 1500.

60
00:07:24,780 --> 00:07:29,070
The product of two values A and B was poured into a result three.

61
00:07:29,280 --> 00:07:33,600
And its value is equal to 1500.

62
00:07:33,960 --> 00:07:40,740
And we could use from multiplication, operate another case division.

63
00:07:41,610 --> 00:07:47,360
Now you want to give an example of a division first year the last.

64
00:07:52,140 --> 00:07:59,220
Now define a variable like result for and divide the values A and B by each other and put the result

65
00:07:59,220 --> 00:08:00,180
into it.

66
00:08:00,620 --> 00:08:08,820
So the right result for column equals a Division B go to the next line.

67
00:08:09,510 --> 00:08:12,530
Division D y is the numerator by the denominator.

68
00:08:12,540 --> 00:08:17,700
In this case, Division A and B now write following code to display the output.

69
00:08:17,700 --> 00:08:32,100
So we write that f the division resolved o a and B equals percent d.

70
00:08:32,610 --> 00:08:39,290
And we said resolved for reform at the court, save the project and execute the program.

71
00:08:42,220 --> 00:08:48,190
Now we can see the output division result A and B equals one.

72
00:08:49,570 --> 00:08:54,250
The division of two values A and B was performed into resolve four.

73
00:08:54,580 --> 00:08:56,710
And its value is equal to one.

74
00:08:56,980 --> 00:09:02,980
And we could use from division print another, which is modulus.

75
00:09:04,000 --> 00:09:07,300
Now we want to give an example of modulus.

76
00:09:08,330 --> 00:09:09,880
First, clear, the last code

77
00:09:16,090 --> 00:09:24,010
defined a variable like result fine and divide the values A and B by each other and put the result into

78
00:09:24,010 --> 00:09:24,340
it.

79
00:09:25,300 --> 00:09:31,510
For example, result five column equals a modulus.

80
00:09:31,900 --> 00:09:34,930
B Go to the next line.

81
00:09:35,590 --> 00:09:42,790
Modulus operands gives the reminder after an integer division civil rights following code to display

82
00:09:42,790 --> 00:09:47,590
an output f f modulus

83
00:09:51,340 --> 00:10:10,300
resolved of a person to person B equals person D and you said result func reformat the code, save the

84
00:10:10,300 --> 00:10:13,150
project and execute the program.

85
00:10:15,910 --> 00:10:22,450
Now we can see the output modulus result of A and B equals 20.

86
00:10:23,350 --> 00:10:31,330
The number A was divided by the number B and the reminder was added to the reason five variable and

87
00:10:31,330 --> 00:10:37,540
we could use from Division OFFRANT and other case increments.

88
00:10:38,290 --> 00:10:41,650
Now we want to give an example of an increment.

89
00:10:41,800 --> 00:10:43,930
So first year the last code.

90
00:10:47,470 --> 00:10:52,090
First, define a variable like a calling equals 20

91
00:10:54,640 --> 00:11:02,950
and increment the value of a variable bought before 48, we want to display the variable a FP.

92
00:11:04,300 --> 00:11:09,820
To be four in climate

93
00:11:12,790 --> 00:11:22,040
display and increment a variable increment or plans increases the integer value one by one.

94
00:11:22,060 --> 00:11:35,920
So you write a plus plus and go to the next line and display a again FP after increments and you display

95
00:11:36,340 --> 00:11:41,650
a deformity called Save the Project and execute the program.

96
00:11:44,570 --> 00:11:53,450
Now we can see the output before Increment A is 20 and after Increment A is twenty one, so we could

97
00:11:53,450 --> 00:11:55,550
use for an increment offrent.

98
00:11:56,900 --> 00:11:58,980
Another case decrements.

99
00:11:59,960 --> 00:12:04,790
Now we want to give an example of decree meant first to your last quote,

100
00:12:08,900 --> 00:12:15,680
define a variable like a and initialize it by 20 and display before the agreement it.

101
00:12:16,250 --> 00:12:24,260
And now we want to decrement to a variable decrement or print decreases the integer value one by one.

102
00:12:24,560 --> 00:12:31,520
So we write a minus minus and go to the next line and display a variable again.

103
00:12:31,550 --> 00:12:32,300
If the.

104
00:12:34,560 --> 00:12:35,220
After.

105
00:12:38,080 --> 00:12:39,100
The agreement.

106
00:12:41,910 --> 00:12:48,870
And it is really a here we change it to be for the agreement.

107
00:12:52,280 --> 00:12:56,030
Reformat the code, save the project and execute the program.

108
00:12:58,370 --> 00:13:05,720
Now we can see the output before the climb in the value variable A is 20 and after decrement, the value

109
00:13:05,720 --> 00:13:07,550
of a variable is 90.

110
00:13:08,090 --> 00:13:14,030
And we could use from decrement operand in order not to prolong the time of decision.

111
00:13:14,030 --> 00:13:17,550
We will finish it and we will continue the content in the next session.

112
00:13:17,570 --> 00:13:18,050
Goodbye.
