1

00:00:02,170 --> 00:00:04,000

Hey, guys, what's up?



2

00:00:04,780 --> 00:00:08,680

So in this session, we will try to understand the difference between.



3

00:00:10,260 --> 00:00:10,920

Forced.



4

00:00:12,600 --> 00:00:15,900

Three incrementing diclemente.



5

00:00:21,880 --> 00:00:25,930

OK, so suppose I am having a equals one.



6

00:00:27,040 --> 00:00:32,740

So if I write a equals A plus one, the value of A will be incremented by one.



7

00:00:33,070 --> 00:00:37,200

We have seen this in flowchart and sort of to the valley of AVL.



8

00:00:37,200 --> 00:00:38,820

We incremented to one.



9

00:00:39,680 --> 00:00:39,930

OK.



10

00:00:40,990 --> 00:00:45,700

Now, instead of writing equals eight plus one, I can also write the A plus.



11

00:00:45,700 --> 00:00:48,170

Plus they both same.



12

00:00:48,370 --> 00:00:48,660

OK.



13

00:00:49,480 --> 00:00:51,130

They both tie same.



14

00:00:53,060 --> 00:00:53,540

So.



15

00:00:54,540 --> 00:00:55,080

Let's see.



16

00:01:06,480 --> 00:01:11,100

So let's name it forced entry post pre.



17

00:01:32,740 --> 00:01:37,030

So suppose I am having and a close one.



18

00:01:38,230 --> 00:01:43,030

So a variable and and the value of that variable is initialized to one.



19

00:01:44,470 --> 00:01:47,290

Now I'm inheriting including the value OWFI by one.



20

00:01:47,780 --> 00:01:48,010

OK.



21

00:01:49,060 --> 00:01:51,700

And now I am printing the value OWFI.



22

00:01:55,360 --> 00:01:58,240

So what should be my output, output should be to.



23

00:02:01,080 --> 00:02:02,340

So, too, is getting printed.



24

00:02:02,610 --> 00:02:03,100

No doubt.



25

00:02:03,410 --> 00:02:05,520

OK, so this is called.



26

00:02:08,890 --> 00:02:09,790

Post agreement.



27

00:02:12,680 --> 00:02:14,660

It is just incrementing the value of eBay.



28

00:02:15,080 --> 00:02:18,010

Well, knowledge commanded out.



29

00:02:30,660 --> 00:02:32,970

Now I am keeping everything same.



30

00:02:35,900 --> 00:02:36,620

Breeding agreement.



31

00:02:37,070 --> 00:02:42,800

So instead of writing E-Plus Plus plus, what I'm gonna do is I will write plus Plessey.



32

00:02:45,180 --> 00:02:49,430

OK, so this is the only change here, it was Iblis place.



33

00:02:49,490 --> 00:02:51,080

Now it is plus pressie.



34

00:02:52,120 --> 00:02:53,250

So what should be my output?



35

00:02:55,890 --> 00:02:57,360

So the output is again.



36

00:02:58,340 --> 00:03:00,980

OK, so the output is again to.



37

00:03:06,050 --> 00:03:11,750

So when I was writing E-Plus plus, then also the value offie was to.



38

00:03:13,050 --> 00:03:18,540

And when I am writing plus Plessey, then also the value OWFI becomes too.



39

00:03:19,290 --> 00:03:23,400

I'm calling it Post Incremented and I'm calling it Brene Agreement.



40

00:03:25,780 --> 00:03:29,320

And this in so I there are two different names.



41

00:03:30,400 --> 00:03:31,840

So there must be some defense.



42

00:03:32,930 --> 00:03:36,190

OK, so there must be some difference between E-Plus Bless and Bless Plessey.



43

00:03:37,130 --> 00:03:40,760

And in this video, we will try to understand what is the difference.



44

00:03:42,260 --> 00:03:43,120

OK, so let's see.



45

00:03:45,470 --> 00:03:47,260

So also commented out.



46

00:03:54,240 --> 00:03:55,920

Now, let's see what is their defense.



47

00:03:57,060 --> 00:04:00,390

So I am taking to variable A and X.



48

00:04:01,590 --> 00:04:03,570

So suppose the value of A's when.



49

00:04:06,460 --> 00:04:08,250

OK, so the value of phase one.



50

00:04:09,150 --> 00:04:17,160

Now I am writing X equals E plus plus and now we will print the value of X entity.



51

00:04:17,640 --> 00:04:25,790

So C O takes and line C out a line.



52

00:04:27,720 --> 00:04:27,980

OK.



53

00:04:28,890 --> 00:04:30,750

So what will be my output.



54

00:04:32,280 --> 00:04:32,770

Let's see.



55

00:04:38,020 --> 00:04:41,740

So the value of X is one and the value of A's to.



56

00:04:44,690 --> 00:04:46,110

Lancy Visored, so.



57

00:04:52,090 --> 00:04:53,860

So initially, the Valium phase one.



58

00:04:55,290 --> 00:04:58,230

And I am writing X equals a plus plus.



59

00:04:59,600 --> 00:05:00,830

So what is happening here?



60

00:05:04,690 --> 00:05:05,830

So what is happening here?



61

00:05:06,730 --> 00:05:09,220

This thing is called Borst Increment.



62

00:05:10,240 --> 00:05:12,840

So in Boston and what will happen first?



63

00:05:13,240 --> 00:05:15,340

I will assign the value of a.



64

00:05:17,350 --> 00:05:20,200

And then I will incremented the Valy Elfie.



65

00:05:21,450 --> 00:05:21,820

OK.



66

00:05:22,110 --> 00:05:25,980

So when you're writing X, it was a plus plus.



67

00:05:26,820 --> 00:05:34,830

First, the Vendee of A is assigned to X and then the value of A is incremented.



68

00:05:35,610 --> 00:05:37,710

That's why it is called Borst.



69

00:05:40,860 --> 00:05:49,500

Boasting limited means, first I sign, then increment.



70

00:05:51,980 --> 00:05:55,900

And that is the reason the value of X equals Iblis place.



71

00:05:56,450 --> 00:05:57,920

So first the value of AIZMAN.



72

00:05:59,600 --> 00:06:05,660

Since that is assigned to X, that's why the value of X will become one and then the value of it will



73

00:06:05,660 --> 00:06:06,500

be incremented.



74

00:06:06,620 --> 00:06:08,290

So the value of it will become, too.



75

00:06:09,220 --> 00:06:09,520

Okay.



76

00:06:09,830 --> 00:06:12,140

So that's why I hear my output was one.



77

00:06:12,650 --> 00:06:14,600

And in this line, my output was to.



78

00:06:16,180 --> 00:06:19,690

Now, let's see what will happen in case of increment.



79

00:06:20,980 --> 00:06:22,930

So condole see?



80

00:06:26,140 --> 00:06:27,330

Condole Gandolfi.



81

00:06:29,170 --> 00:06:32,200

Instead of riding a plus plus murder, I really do.



82

00:06:32,260 --> 00:06:32,850

I will ride.



83

00:06:33,340 --> 00:06:34,000

Bless Plessey.



84

00:06:35,480 --> 00:06:36,730

And let's Commander Daoud.



85

00:06:42,360 --> 00:06:43,760

So let's see.



86

00:06:46,380 --> 00:06:52,080

Here you can see the value of X is too, and the value of Faisal also Sorto, in previous case, the



87

00:06:52,080 --> 00:06:53,520

value of X was one.



88

00:06:55,730 --> 00:06:56,850

Now, what is happening here?



89

00:07:01,000 --> 00:07:01,990

So, ex.



90

00:07:03,860 --> 00:07:07,070

It was Bless Bless a.



91

00:07:08,940 --> 00:07:14,810

It is called pre increment plus Plessey is called Reimplement.



92

00:07:14,990 --> 00:07:16,030

It will do the opposite.



93

00:07:16,490 --> 00:07:18,170

First it will increment.



94

00:07:20,620 --> 00:07:22,690

Then assign.



95

00:07:27,410 --> 00:07:27,660

OK.



96

00:07:28,010 --> 00:07:31,100

So this statement will be evaluated first.



97

00:07:31,250 --> 00:07:35,930

First, the value of a will be incremented and then the value fee will be assigned.



98

00:07:36,770 --> 00:07:42,090

So fast it will become two and then X equals eight, which is two.



99

00:07:43,060 --> 00:07:44,910

That is the reason hair.



100

00:07:44,960 --> 00:07:47,120

My output is two and two.



101

00:07:49,350 --> 00:07:53,280

So I hope the difference between post and being made is clear.



102

00:07:54,000 --> 00:08:00,030

OK, so being agreement means first you're doing Kliment and then you do the assignment.



103

00:08:00,840 --> 00:08:06,480

And in case of post increment, first you assign and then you increment.



104

00:08:08,250 --> 00:08:08,440

OK.



105

00:08:08,490 --> 00:08:13,020

So first you will assign and then you will do the increment.



106

00:08:13,710 --> 00:08:19,410

But in this case, first you will do the increment and then you will assign.



107

00:08:21,950 --> 00:08:25,130

OK, so the difference between post and bring him on this clear.



108

00:08:26,570 --> 00:08:30,920

Now the same thing happens with Post and Beauty Clement Desmond.



109

00:08:37,890 --> 00:08:39,180

So I'm copying this part.



110

00:08:41,410 --> 00:08:42,260

Condole, see?



111

00:08:45,510 --> 00:08:45,960

Candlewick.



112

00:08:52,170 --> 00:08:56,030

So head of a little phase one now in knowing gives off.



113

00:08:57,060 --> 00:08:58,470

Now I am diclemente angered.



114

00:08:58,710 --> 00:09:03,210

OK, so a minus minus eight minus minus means decrease the value of a bye.



115

00:09:03,420 --> 00:09:03,760

When.



116

00:09:08,950 --> 00:09:17,500

Equals eight plus one and a plus plus they both seem similarly equals A minus one and E minus minus.



117

00:09:17,560 --> 00:09:20,140

They both also seem OK.



118

00:09:22,800 --> 00:09:27,240

So it is pre the kliment sorry, it is post degremont.



119

00:09:29,880 --> 00:09:30,390

Post.



120

00:09:33,780 --> 00:09:34,450

Degremont.



121

00:09:35,750 --> 00:09:41,800

So the value of Aizman now, the value of a is decrescendo by one for the new Vello will become zero.



122

00:09:42,200 --> 00:09:43,730

And then you are printing zero.



123

00:09:44,430 --> 00:09:45,500

In this case also.



124

00:09:46,910 --> 00:09:49,210

So first, let Lidstrom this part.



125

00:09:52,030 --> 00:09:54,690

So now Edwards coming out with zero as expected.



126

00:09:56,430 --> 00:09:57,980

Now let's comment out this part.



127

00:10:02,390 --> 00:10:03,590

And we will run this part.



128

00:10:05,820 --> 00:10:11,420

So the only change Naadam I'm gonna do is minus minus a hair.



129

00:10:11,620 --> 00:10:12,930

It was a minus minus.



130

00:10:12,960 --> 00:10:14,480

Now it is minus minus.



131

00:10:15,450 --> 00:10:17,130

And it is really Kliment.



132

00:10:19,720 --> 00:10:20,730

Okay, so what will happen?



133

00:10:21,090 --> 00:10:24,240

The value of Aizman, the value of it will relate remaindered.



134

00:10:24,330 --> 00:10:27,540

Now the new relevé will become zero as it was getting printed.



135

00:10:30,120 --> 00:10:30,310

OK.



136

00:10:30,510 --> 00:10:30,890

Zero.



137

00:10:36,710 --> 00:10:40,520

So when I was writing a minus minus.



138

00:10:40,610 --> 00:10:42,170

Then also my output was zero.



139

00:10:42,470 --> 00:10:46,880

And my when when I am writing minus minus say they don't amount to zero.



140

00:10:47,900 --> 00:10:50,180

But I'm calling it does bolster decrement.



141

00:10:50,540 --> 00:10:52,520

And I calling it days predicament.



142

00:10:54,240 --> 00:11:01,410

So there should be some defense and the defenses, same as we saw in a blessed, blessed and blessed



143

00:11:01,410 --> 00:11:01,780

blessing.



144

00:11:02,920 --> 00:11:03,720

OK, so let's see.



145

00:11:05,510 --> 00:11:10,110

I will copy this part and don't see.



146

00:11:19,810 --> 00:11:20,900

Now equals one.



147

00:11:21,210 --> 00:11:21,920

What I will do.



148

00:11:22,120 --> 00:11:24,550

I will write a minus minus.



149

00:11:25,610 --> 00:11:25,870

OK.



150

00:11:27,090 --> 00:11:27,890

So let's send it.



151

00:11:30,690 --> 00:11:34,820

So the value of X is one and the value of phase zero as expected.



152

00:11:38,370 --> 00:11:47,570

So initially, the value of is when and then you are writing X equals a minus minus, which is both



153

00:11:47,570 --> 00:11:51,750

to the agreement post means first you will assign the value.



154

00:11:52,200 --> 00:11:54,600

Now the value of X equals one.



155

00:11:54,690 --> 00:11:57,540

And then you we decrease the value.



156

00:11:57,600 --> 00:11:59,250

So the value of phase zero.



157

00:11:59,700 --> 00:12:03,150

You can see here the value of X is one and the value of A's zero.



158

00:12:04,260 --> 00:12:05,910

So this was boaster decrement.



159

00:12:05,970 --> 00:12:06,300

OK.



160

00:12:06,750 --> 00:12:09,680

So this was post the agreement.



161

00:12:11,950 --> 00:12:13,720

Now, let's see predicament.



162

00:12:25,480 --> 00:12:28,570

So last year of our doing plus policy, minus minus.



163

00:12:29,260 --> 00:12:32,050

So hatred was a minus minus.



164

00:12:32,550 --> 00:12:34,440

Here it is, minus minus he.



165

00:12:38,740 --> 00:12:41,850

So the value of X and a bow tie.



166

00:12:42,260 --> 00:12:42,670

Zero.



167

00:12:43,240 --> 00:12:43,550

Why?



168

00:12:44,230 --> 00:12:45,850

It is bleeding, Kliment.



169

00:12:46,830 --> 00:12:48,690

So initially, the value of phase one.



170

00:12:49,940 --> 00:12:53,150

Then X, it was minus minus E.



171

00:12:54,950 --> 00:13:05,270

So since it is pretty agreement, first I will decrease the value of A becomes zero and then I will



172

00:13:05,390 --> 00:13:05,960

assign.



173

00:13:08,190 --> 00:13:10,030

Hence exs also zero.



174

00:13:10,110 --> 00:13:11,330

And that's why water.



175

00:13:11,680 --> 00:13:12,060

Zero.



176

00:13:13,340 --> 00:13:16,410

OK, so this was through the Cleveland.



177

00:13:21,130 --> 00:13:22,660

So I hope the picture is clear.



178

00:13:24,490 --> 00:13:30,150

So I hope now you're not the difference between a plus press and less blasé.



179

00:13:31,270 --> 00:13:33,480

A minus, minus and minus minus.



180

00:13:35,110 --> 00:13:37,810

They both had increasing the value by one.



181

00:13:38,500 --> 00:13:40,810

And they both had decreasing the value.



182

00:13:41,530 --> 00:13:44,060

They both are decreasing the value by one.



183

00:13:45,130 --> 00:13:46,270

This is posed.



184

00:13:48,040 --> 00:13:48,850

This is pre.



185

00:13:49,870 --> 00:13:51,460

Similarly, this is post.



186

00:13:52,840 --> 00:13:57,140

This is the post means first.



187

00:13:57,460 --> 00:14:01,870

You assign and then you increment or decrease.



188

00:14:02,410 --> 00:14:03,090

Three means.



189

00:14:04,030 --> 00:14:06,520

First, you increase or decrease.



190

00:14:06,790 --> 00:14:07,720

And then you assign.



191

00:14:09,160 --> 00:14:09,440

OK.



192

00:14:09,790 --> 00:14:12,790

So this is the basic difference between post and pre.



193

00:14:13,810 --> 00:14:14,270

Thank you.
