COPY CONSTRUCTOR IN C++ ( 33)

COPY CONSTRUCTOR IN C++
The copy constructor is a constructor which creates an object by initializing it with an object of the same class, which has been created previously. The copy constructor is used to:
Initialize one object from another of the same type.
Copy an object to pass it as an argument to a function.
Copy an object to return it from a function.
If a copy constructor is not defined in a class, the compiler itself defines one.If the class has pointer variables and has some dynamic memory allocations, then it is a must to have a copy constructor.

Hey Guys, I have made a mistake at 2:35 There are only two forms of calling copy constructor. ------------------------------ example obj1(50); example obj2; obj2 = obj1; This is not invoking the Copy Constructor. ------------------------------ Here assignment operator(=) is overloaded by default by the Compiler. I am truly sorry Guys, it won't happen again. ---------------------------------------------------------------- Special Thanks to Mayuri Popat for pointing out my Mistake.

[@ashutosmisraa]

Mayuri ne Popat kr diya js kiddin(. ❛ ᴗ ❛.)

[@dhirajdarakhe3808]

Thanks

[@thrishulh9834]

but in ur deep copy shallow copy video assignment operator is indeed invoking ur custom defined copy constructor

[@Harsimran_Singh_27]

There are many C++ programming tutorials on KZbin but to understand most of them, you really need to be very attentive and after watching one or two of those videos, you get saturated and feel unable to move further. You are unable to watch more than 3-4 videos at a stretch - but these tutorials are so beautiful. These are so simple, easy on the mind and effective. This is a revolutionary channel. Brilliant work... Keep uploading more videos to help Computer Science students and to make it easier for us to earn our degrees !!!

[@Codearchery]

Thank u so much Harsimran . I think , I achieved my Goal. Thanks a lot for this comment and I will keep on uploading more good stuff Don't forget to share and Keep on watching and keep on learning

[@cautioni]

Don't stop. Keep uploading, understanding programming has never been this fun and easy.

[@annonymousfox7515]

These are the best videos on C++ I've seen on youTube!! You are amazing and thank you so much for creating this! I hope these videos make you rich cuz you deserve it! Keep it up!

[@Codearchery]

Thanks AnonymousFox Have you seen Codearchery.com teaser? kzbin.info/www/bejne/maKvlZ94ltSbgrc Did you like it ?

[@imadvurkadinohinto]

when we try to copy any constructor manually we are doing a kind of copy that allows us to access to the current copied constructor's attributes, which means we can change a particular attribute values as well us keeping them as they are. thanks Codearchery for this awesome explanation.

[@helios9595]

For The First Time in my life I enjoyed and very interested watch lectures. just keep going on dont change your style.

[@rhitikkrishnani510]

I am preparing for my placements. These lectures are really helpful. Thank you sir !!

[@manishkumar1450]

crisp and clear approach of teaching.

[@supersaiyanlimitbreaker3018]

Very well presented. easy to understand.

[@mugiifeed6156]

Love and respect from Sri Lanka,This is the Great Video series on C++

[@theanger5930]

Despite the mistake you made, this video is just on point. You explained everything so well, thank you.

[@shaikhtanzil2630]

plz never stop making videos like this

[@esabkhan7901]

You Know ,how to make people understand something , better than many.

[@kirthikas1896]

Truly by watching your video alone I'm going to attend my sem, with lot more confidence! Never ever stop doing this :) you are tooo great !

[@ramachandraudupi6641]

But sir,"data" is private member data,i understand dummy is a reference to obj1 in this example I don't have a doubt in that,but how could you use dummy.data in copy constructor???can someone help please!!!!!!

[@Pishkoo]

Just wow...Superbly awesome 🥰

[@yunaimenodacid5828]

Hi, when you write exmaple ob1(50); example obj2; are calling parameterise and default constructor. When you write obj2 = obj1; them is calling assigment operator. I think. Great videos.

[@mohammadawaisrana8878]

Very nice teaching method😍

[@IslamIslam-hd1ow]

That's really helped me thank you

[@usama57926]

bro which software u use for making these videos

[@mugiifeed6156]

video scribe

[@ariyanpritom9071]

Yes Bro. Your video deserves LIKE.

[@shivanigoswami2773]

Difference way unique explanation... Can easily understand all concept within 4 to 5 min only.thats a great video smart work I like.it👌👌👌👌

[@areegahmed3926]

LITERALLY THE BESTTTT!!!!!!!!!

[@vkj5742]

why have you written & symbol in the argument list of copy constructor? explain please.

[@shivanigoswami2773]

Really I was enjoying it Fully satisfied for this concept in this way thank you

[@shoaibkhairmuhammad9695]

Why we use two variables x and data.. One is for copying other value?

[@AlkaSharma391]

Saw many videos but never see this type of video Amazing

[@vanshikaanand3969]

isn't the second way of calling copy constructor '=' operator overloading??!

[@tanveerasif5978]

you didn't explain:- 1- Shallow copy n deep copy 2- Copy constructor parameter : why const specifier n pass by reference

[@MASBHANOMAN]

really appreciated good work...

[@Codearchery]

Thanks Masbha for watching my videos :-) I hope you'll love to help me by sharing My Channel with Your Friends Keep on Watching and Keep on Learning

How I practice c++ programming to clear each concepts and also how to improve logic pls tell me sir your videos are really help me to learn c++ keep making videos.....🙏👍

[@mohansrikri]

Can you explain shallow copy and deep copy concepts...

[@Codearchery]

Yeah why not , I will be uploading the videos in upcoming few days

[@sanketsharma7141]

So amazing.... Superb....Kya KZbinr h yr....

[@usama57926]

u r great explanier

[@samaryadav7208]

@2:34 is assignment operator NOT copy constructor. Else it is a great video.

[@JeesJoy]

Samar Yadav it is a copy constructor

[@rashidakhatun7437]

Thanks a lot

[@poojasalvi1262]

How to practice c++ programming to clear each & every concepts & also how to develop logic pls tell me sir.....🙏👍

[@Shubham-xh9nz]

3:06 whats that example ( example & data){ data = dummy.data } is syntax of copy constructer ? Or something else

[@Codearchery]

You got it right , this one is the syntax of copy constructor

[@nawalkishoresingh4794]

Nice video. But copy constructor manually is not clear to me. Any video reference for understanding copy constructor manually , for clearing our concept

[@rushdaquraishi2206]

Really awesome way to teach using animation. I love it keep updating

[@michaelvela2835]

Great video!

[@ganeshbhavana1061]

I appreciate u r work

[@QuickTale55]

Tks for a good video

[@SanthoshAS-x6u]

but what is the use '&' in copy operator???

[@paridhimodi2450]

i never get what my teacher teaches in skul. but aftr watching your videos i understood everything written in book

[@Codearchery]

Wow....... I am happy that My Channel is so much Useful Hey Parishi Share My Channel with Your Teacher :-P So that your teacher can teach the fun in Programming to students

[@paridhimodi2450]

hahaha for sure

[@paridhimodi2450]

never mind

[@paridhimodi2450]

can you pls upload videos of pointers

[@xxkingcoreyxx5499]

yoooo nice job,good work man please carry on

[@deepakborah8335]

Sir As compiler will make a copy constructor if we don't make. In actual argument we are passing obj2 of example type as, example obj1(obj2).It means we are passing value of example type of obj2.. Why we need to put reference operator at formal argument inside the parentheses eg. example ( example &dummy) to copy obj1 to obj2 ? Here dummy is nothing but obj2 .Without reference operator it gives error.The content will be copied to obj1 no doubt. Why reference operator is compulsory. Is there any other way to copy without & operator.?

[@anyk.3741]

I'm confused . Example obj2; obj2 =obj 1 ; how does this involves copy constructor as object is not copyed at construction.

[@samaryadav7208]

it's not. He made a mistake. It is actually assignment operator.

[@sarveshkaran9380]

right its assignment operator call,not copy constructor

[@saurabhs4743]

Why does the default contructor have access specifier?

[@amerbangla7256]

great job dear just outstanding tutorials

[@ahmedalaa9214]

I hope all the best for you ❤️

Thanks a lot man

[@RahulKumar-tf8uq]

good concept.. i like the way you teach

[@Codearchery]

Thanks a lot Rahul , I hope you'll love to share this channel with your friends too . Keep on Watching and learning :-)

[@Vishakitha]

Why some programs in use int main() then some programs in use void main() if I wrote the program how I choose main() bro

[@exoticme4760]

as always SUPERB !

[@Gurpreet11g]

Sir pls make video on type conversion -basic to class, class to basic or class to class.

[@jattsuryanshchoudhary6927]

sir small doubt in copy constructor defining... data=dummy.data this line is not properly clear

[@Codearchery]

look we are copying data manually so we are representing dummy as object. the variable data belongs to the newly created object. And dummy.data means data variable which is present in the object dummy. Okay You might get confused with all of this , Keep on Watching further videos and Keep on Practicing You will understand what this line means when you practice a lot:-)

[@cyborgdale]

Suryansh Choudhary The copy constructor is a function and therefore behaves like other functions. Here the object, obj1, is passed-by-reference so it is automatically dereferenced just by saying "dummy.data" (instead of "(*dummy).data" or "dummy->data".) The calling object is obj2 so "data" needs no "object_name..." in front of it. (Remember, as far as the written code goes, the only difference between passed-by-reference and pass-by-value is the & in the parameter list. Everything else in the text is the same.) Does that help?

[@joeydicastro]

Very good video and so funny, btw it is always a good practice to set copy constructor params as const reference :)

[@Ms_Priya26]

But in this prgm u didn't creat object for default constructor? Other two objects carry parameters... Then how it'll run default constructor.... But ur prgm has executed!!!! 🤷🏼‍♀️ Help me to clear this doubt

[@احمدسليم-ن4ل]

Very good

[@theradhikagupta]

Please make videos of c++ 11 and c++14 concepts
