[@luckyabby2871]

conio.h is only in Turbo C++, what is the similar header file for standard C++ ?

[@luckyabby2871]

this is only shallow copy constructor, you forgot deep copy constructor.

[@akshaynikam8508]

If i dont want to write copy constructor then what is another option for copy constructor...
Plz guide...

[@BiharCentralSchool]

I got tired to search & see the many lectures on Copy Constructor but didn't understand, BUT THIS 15 MIN VIDEO TAUGHT ME FROM SCRATCH. THANK U SIR

[@arjunsuresh932]

I rarely comment on UA-cam..But this is a very clear nd solid explanation that i found difficult to understand elsewhere out in the internet..Thank you SIR :)

[@gamuchiraimureyani281]

Super and nice prof. i have ever seen in USA!!!!

[@jaysalunke4214]

Thank you Naresh technologies for making concepts so simple.

[@Pluxlite]

Oh thank you! this is the first time i actually understood copy constructor!

[@meilyn22]

Best explanation in the world.

[@belevtsof]

Very good explaining, excellent ! Thank so much from Ukraine

[@TheGeekyTuber]

Has to be the most vivid explanation on copy constructors.

[@KaifAli-k8m]

One of the best lecture on Copy Constructor......😊

[@shubhangih5309]

Sir please make a video on Parameterized Constructor

[@wings7494]

It is there in playlist

[@saikun0293]

Why don't we directly write old instead of &old shouldn't it make old a copy of the class passed
for eg if we write sample s2(s1) then old is a copy of s1 and thus a=old.a
because this is how we pass integers also
for eg:
print(int num)
{
cout

[@aishwaryabobe5397]

Excellent explaination sir... Thanks a lot.. upload all videos related to c++

[@prateekbhojwani9909]

I appreciate Mr. Kishore for such videos. Nice work . Keep going

Awesome xplanation sir
Tq very much

[@InterviewPoint]

Thank you Sir for this video, Sir please make a video on Parameterized Constructor

[@sendhoorasukeshpk6261]

It's so useful for me
Thank you so much

[@mukulrana1616]

Perfect n smooth explanation

[@heenamalek6001]

superb sir Thank You 🙏

[@gowthamis7172]

tiz is first time understood da copy constructor after watching ur videos sir tqqq

[@tushardalave4619]

Very good lecture

[@jeevadas2056]

I would like to bring your attention towards syntax of copy constructor and importance of const keyword. const keyword should be added to avoid accidental modification ,a temporary object cannot bind to a non-const reference

[@vishaljhaveri6176]

Very well explained keeping the grips on the essential part of the programs.

[@Userindia14567]

Excellent👍

[@deepakborah8335]

Good explanation about copy constructor.

[@janardhanjackichan7435]

Explanation super ga undi mi videos download chasukunna from play store

[@SHRAVANKUMAR-yu5cv]

Great 🙏

[@edipsaln]

Very good explanation. Thank you.

[@stuartdhas8468]

The reference object passed should be const in nature (preferebly)

[@pratimashashank4601]

Very good explanation sir

[@cr7johnChan]

Thank You sir !

[@viswanathgupta7406]

Super Explanation Sir

[@iniyaviji2796]

Thank u sir hats of u

[@dipendrabharati6256]

Great Explanation , Thankyou

[@sanamyaqoob3740]

thank u it is very useful for me to understand inheritance

[@Pishkoo]

Perfectly awsome🥰

[@subhajitadhikary155]

Thanks a lot sir, really great explanation

[@moayyadarz2965]

amazing teacher ı like your way of explaining the ideas

[@Raam1827]

If you gave example with pointer and shallow copy and deep copy in this topic it will much helpful to all

[@romelelectronics]

thank you sir, u r real kind teacher

[@SarathKumar-tm6ui]

thank you so much sir wonderful explanation

[@archanajames2468]

Brilliant

[@pratikpatil3469]

Sir U haven't made any video on parameterized constrictor please make one video on it

[@chayanbandyopadhyay1227]

sir i have a doubt regarding the calling of the copy constructor.... in void main... shall it be sample &s2(s1) ???? please reply sir..!!
best xplanation ..!!thanks alot sir..!!

[@adityaTheLaughingMonk]

givl pgg

[@arbindmahato2371]

U r great sir

[@prabha8682]

Thanx for helping

[@neerajmahajan9457]

Best♥

[@govinddwivedy8145]

Sir will you please clarify ,why you used & in copy constructor

[@anjucreations8124]

copy constructors depends on reference(&) to same class type.

[@jonathanmedranodanes5508]

I have a question: a and b are private variables of s1, using reference variable can bypass data hiding then?

[@unfinished.education]

supper se upper sir

[@bhaumikk7893]

good one..

[@madhavikatta7346]

In c++ there is default copy constructor. No need to write separate copy constructor until unless use the dynamic memory allocated to avoid dangling pointer. Sir my sincere request pls give the proper subject to the learners.

[@the_aravinth_m]

Sir ... I don't know why u have deleted the symbal & at timestamp 11:25 ..? anyone plz clarify

[@girishb2801]

There should be use of const operator in copy constructor argument. Pls check

[@RifadIslam]

His English accent is just perfect than any other Indian peoples :3

[@Beyond007P]

Excellent

[@quamzgraphix9826]

thank you sir...

[@jishnujishnu849]

What is the relavance of &old there
Can you please explain

[@nilaypaul9810]

The reference variable means "An alternative Name for the previously defined variable or object or whatever"
So when Sample S2(S1) is passed; that means the object S1 is got new name of "OLD"
Now, as you can see S1 object has for a= 10 and b = 20;
So, in S2,
a = old.a; //old is object S1
b = old.b //old is another name for object S2

[@pitrya2533]

Sometimes we make use of "const" keyword in copy constructor(like sample (sample const &old) What's the purpose?

[@jeevadas2056]

I would like to bring your attention towards syntax of copy constructor and importance of const keyword. const keyword should be added to avoid accidental modification ,a temporary object cannot bind to a non-const reference

[@hrishikeshkulkarni2856]

awesome sir

[@rameshjogi8501]

What is shallow and deep copy ???

[@sammydeew4773]

can u pls explain C programming

[@bipinkhangar3346]

Sir but "this" function me . Nhi chalta na wo to java me hota hai.....cpp me this-> aisa hota hai na shyad???

[@bilalsheikh5786]

(*this).a and this->a are different syntax for the same operation. You are right that -> is a typical java operator, but it is implemented in newer C++ as well.

[@shinjomoxuba8779]

If you are coping all the value of s2 in copy constructor then why do you used parameterize constructor ...
Ans please🙏🙏🙏

[@pratikkunthe6472]

Sir where is parameterized constructor??

[@vsarts1967]

Watch video number 31 , overloading example 1

[@amazingcreator3744]

Sir can we write s2=s1 like this?

[@danumichael4864]

thanks sir

[@viswanathgupta7406]

Add more session sir

[@cristo_sal]

What about copying pointer variables?

[@sreyashreepal3146]

where is the parameterized constructor video?? Can anyone share the link??

[@ayushshah7831]

best sir

[@kalairavichandran558]

sir,why you removed & in s2

[@sofimajeed8342]

That should not be there

[@rajasekharburgala]

Sample (S2)=S1 Equals to sample S2 = S1, so & is not required

[@sanjeevkant8470]

I think you have to use constant for reference object in copy constructor parameter, otherwise the old object values can be manipulated inside copy constructor, just a suggestion from my side.

[@VideoLanxer]

I believe the answer will be 10,20 and 10,20
If the answer is same twice, what is the use? ,🤔🤔🤔

[@iAlienGirli]

Let's say you need to create the same object twice (or more) and you need to change one of them during your program or whatever... This is how you should create the same objects

[@MainDoodler]

Good, thanks for the lesson. But everyone's using copy contructor even when they assign as s1=s2. Why's copy constructor also invoking at such occurrence? Anyone knows? :)

[@vikrantmahajan280]

Brother both are valid statement just we need to understand that this s2 value is passing In the constructor.like if we pass two values in constructor we write like s1(4, 3) if we need to pass only one parameter then s1=4 this way is also correct

[@saptarshibose9718]

I think the syntax is class_name(const &old_obj);

[@s.chinna3722]

sir in dev c++ software . its showing error when I place . when I remove (.h) its compiling . can u please give me reason sir

[@jotu2002]

When we use turbo c++ or any old complier (I think ) then we need to use .h otherwise in visual studio or other new compilers there is no need

[@tanvimahajan2697]

where is parameterized constructor video??

[@DewanandSahu01]

lect 30 then 35 then 34

[@akhileshbharati3932]

Asp mere ko thik se Nahi samjha maye
