[@torykidd7570]

Six years later, you're still helping newbie programmers. Thank you.

[@so_called_kabir_singh]

Bro here I'm 9 years later

[@ankitmvp]

Shiv sir is the best mentor. He is the only one who can explain the complex concepts with ease, even to Microsoft devs. 😊

[@Lisa-uq4ty]

You are the first person who explained this in a way I could understand. Thank you!

[@BlueHat1]

Wow! That's honestly the perfect example, thank you so much!

[@kiPROBRos]

Ovo je najbolji tutorijal u vezi Ref parametra.

[@ivanubiamaia9475]

Great tutorial. Now it is very clear the difference between ref and out for me. Thank you!

[@WickedFlamezZ]

Really great video, others are 16minutes long but this tells you everything you need to know in 6.

[@sasirekha9523]

Sir no other articles explained in this correct and prompt way. either it is confusing or left unexplained. you are nailing to the point. hats off to you sir always.

[@alitalipakgun5535]

Wow described perfectly i have no question in my mind about differences between normal, out and ref paramaters after watching the video. Thx pal !

[@Swati_JayRanjan]

I'm really so impressed with the explanation. I have observed the pop up at 0.55 minutes time which puts the wrong statement for default . Could you please correct the same. Rest.... I'm a big fan of your every video. Happy Learning Sir.

[@SumitGupta-wr3jf]

I think 10 time to watch more than 7-8 min videos but you explanation is so sorted even half and hour video i see cause i clears my doubt from top to bottom so i can remember easily....

[@satish6776]

thank you so much!!! I watch many video but not clear this concept. clearly explained and easy example

[@rjbb0377]

Thank you so much! I have had such a hard time trying to understand this, but after listening to you it is so much more clear.

[@DirePantsDim]

Eight years later, and still the best explanation on this topic. You sir, are awesome.

[@tko1176]

Thank you very much. I have a question when is it useful to use the out key world. usually when I call a function it is to do something with the parameters, why would I want the parameters to be generated by the function?

[@akshaytalekar2880]

Ever Ever Simplest Explanation About REF OUT Keywords.

[@d_cl]

The clearest explication I found! Thanks!

[@quaintnet103]

I like all your videos! very informative.....Pls correct the dialog "by default the variables are passed by REF....." to by default the variables are passed by Value..." at 00.51

[@basilio100]

+Quaint Net I would say that PRIMITIVE types passed by value,....

[@liubomirwm]

Actually all types are passed by value, the difference is that primitive types contain their value in the stack and their stack variable (containing the value) is passed. So called reference types have a stack variable which contains not the value directly but the address to the heap (where the actual data is contained). When you pass a so called reference you pass the reference address by value.

[@trenocio8541]

@Taiwo Seiler As far as I know, it doesn't make any difference to add ref to a non primitive type

[@jakebwhite9253]

Thank you! This cleared up the difference. I don’t understand when would someone use “out” though, it seems dangerous!

[@MarcV_IndieGameDev]

Thank you for the video, helped me out.. or should should I say, helped me ref'd

[@manpreet4all]

Sir I think callee doesn't returns any thing... actually the changes are happening in a common address space in case of ref and out so values are refelecting... And in case of out it overwritting with 0 in callee so again common address space is overwritten.... Can you correct me plz where i am wrong.

[@tamaraimani5068]

I appreciate your way of presentation..

[@kskchaitanya]

Hi, can you explain more on this topic... How exactly CLR handles this passing using REF and OUT keywords... Please have a look at the example below: private static string ModifyString(string originalInt) { originalInt = string.Empty; return originalInt; } private static string ModifyString(ref string originalInt) { originalInt = string.Empty; return originalInt; } Both these cases are PassByRef because string is reference type... but using the ref keyword, the changes propagate to the caller. My question is, how is the CalledMethod modifying the pointer information of the CallerMethod - (when the value in the CALLEDMETHOD changes, String creates a new memory location for the new value and assigns the new value location to the CALLEDMETHOD and the CALLERMETHOD at the same time).

[@मयंककेला]

thank you very much but better in (Hindi, Sanskrit ) AnyWay Nice Vdo in Detail Proper Explanation

[@alex_fromrsa4815]

This just simplified the most confusing part of methods for me in 6 minutes. Thanks

[@gnitin0384]

Thank You!! It cleared my long standing doubt

[@stewiegriffin6503]

I understand it. Thanky you. But what would be the idea behind introducing OUT function ? I guess they needed to make some pattern easier. But I don't see any practicaly use of OUT.

[@chezchezchezchez]

Saving CPU cycles and memory and time. No need to pass the data in? Use OUT!

[@RayanMADAO]

I didn't even know about the step by step bugger (f11) before this video, that's a really cool and helpful feature

[@nandorbacso4625]

It was a really good and well understandable video! Thanks, man!

[@mohammedzaid3829]

Best explanation yet! Thank you

[@geetasharma463]

superb explanation thanks now iam confident

Fantastic explanation, thank you so much 👍🏼

[@RahulGupta-jk9lb]

I was confused for ref and out parameters. Now It is clear, thanks!

[@snowblind112]

Perfect explanation, I was totally lost before I found your video. Thank you!

[@jayadulshuvo5857]

That was the easiest explanation of the topic. Thank you.

[@ashishaswal7396]

thank you for this video.. on the net there were all bullshit differences.. now is the main practical difference that made sense why we use them.. keep making these types of videos

Brilliant explanantion, Thank you!!!

[@aungpaingphyo218]

thanks alot!I was having trouble differentiating those two

[@romesupaila1864]

Clean explain ,but I have one query difference between function and method

[@mehmetalper6156]

Very good explanation thanks

[@sery152]

a VERY GOOD EXPLANATION!

[@artwolfgirl]

Thank you for the clear video!

[@BattleandBeyond]

Awesome explanation.

[@tngerik14]

Very good explanation! But please say "by value" instead of "by val", as I think this might confuse beginners

[@niluniverse]

Absolute Explanation ! Thank You Very Much Shiv !

[@grandmagus8618]

is it necessary to define variable while using REF? I think on OUT situation it is not necessary to define variable.

[@kalinduabeysinghe8917]

Beautiful explanation!!!

[@vikramsharma4264]

you are the best teacher !!

[@tauseefakram90]

Very clear explanation with basic example. Thanks !! :)

[@srinivasaraoyp3640]

Very nicely explained Sir. I enjoyed your video...Thank you....

[@MyVideoFinder]

Very nice informative.. I will be very helpful if you able to give links of your domain for the same question in KZbin description.

[@dnfvideo]

+Abdul Qayyum For more info and materials visit www.questpond.com

[@MyVideoFinder]

ok thanks..

[@RayanMADAO]

So basically out only passes the reference and ref passes both the reference and the value?

[@pranavb9768]

Great explaination sir!

[@tvsnmurthy2370]

Hey I want to know In which scenario both are using?

[@chezchezchezchez]

LOL weird no one is talking about THAT!!!!!!!!!!!!!

[@Dismanameboi]

Amazing explanation once again

[@venkatraman4762]

Great Explanation.

[@EduTainer]

What Compiler are you using?

[@preeti1820]

[@hagbard6880]

This Video helped me a lot. Thank you.

[@DarthJeremy364]

this is sooo clear thank you!

[@suniljadhav589]

Nice explanation. Very easy to understand these type of concepts.

[@SonuSingh-nj6vp]

Then what is the benefit to pass the data in parameter what i passing as 20

[@rambabumoorthy5808]

easy to understand thank you

[@mingosutu]

Thanks nice video, however, who is "He" and "Him" you keep using in your explanation?

[@clarkx86]

"He" are the methods he's referring to.

[@NEETHUMOHAN38]

Helped a lot.. Thanks a lot

[@NoName-1337]

Well explained, thank you.

[@codingwithflavio8534]

Why would you pass arguments with out keyword instead of just returning them from the function the regular way?

[@dalamattho2307]

Your video is helping me to give a strong interview thx

[@gauravpun6749]

Thank you soo much ! Nice tutorial !

[@alreadytakenindeed]

Great description, super simple and easy to understand example, thank you!

[@leoc5473]

Incredibly helpful, thank you so much!

[@TheSphynxoid]

So they are lke static which allows you to pass even fonctions

[@santhoshkumarkumaresan5201]

Nice, to add more, the variables should be created before passing to the method for ref and , for out, we can create and pass in method call.

[@dusan7873]

Well explained and simple. Thanks.

[@owenlie]

Best explanation

[@imhappynow8471]

Thank you for nice example

[@mimo8439]

Thanks u made it clear...

[@alexmurghulia6484]

thank you for the explanation, it helped a lot, subscribed.

[@giga_charge]

Very helpful! Thanks!

[@theuntormented6560]

I am very particular about the videos that I click the damned like button Trust me guys this is one of those ❤❤

[@dillikumarreddy1579]

Pretty helpful. Thank you.

[@Monirmahir]

This is worth watching

[@Saandy_]

Definitely cleared up some confusion. thanks!

[@yaminiashok7962]

you are saying when we use out keyword it will not carry data from caller to the callee but instead of insidevar=insidevar+10 just keep insidevar=10 and debug u can observe that value of insidevar=20 in the method somefunction I think you are wrong sorry if i am wrong please verify and confirm us

[@nishant07kumar]

I also believe that in the case of out value will from the main method will be passed to the somefuncton but that value will not be any use as ultimately inside somefunction variable will be initialized and old value will be discarded and new value will be assigned.

[@ourtube9405]

So what is the exact use of out here?

[@manpreet4all]

If the person is wrong, they dont have time to reply...

[@avinashraj25]

Out is used when we need more Return from a function. Function can return Only one value so we have Out keyword. Yes it is of Ref type but we assign the values inside function to this parameter and use it outside of Function.

[@jasper5016]

This is exactly what I thought. out is not actually passing value. Its returning value.

[@Mysteria9]

Fantastic explanation, thank you!

[@Praxss]

But why we use out keyword? means we are declaring variable in function anyway and there not 2 way

[@rohansolse67]

awesome way to explain concept dude

[@desaimihir83]

Well explained, in other words, simplified explanation.

[@jasper5016]

Great video. Thanks. Explanation for out does not make sense. I think out is for returning the value.
