[@sunilpoojari91]

I think so the playlist is not in proper order please check.

[@lovakumari9492]

we need your virtual functions class sir

[@whoisnegii]

Sir where is virtual function video ? I can't be able to find any such video in your tutorials. Please help.

[@dreamvallyhasan4807]

you are the best teacher...thanks a lot

[@vinayakgupta6105]

thank you so much sir you are a god i understood this concept in under 5 min only because of you thank you very much

[@Royal_Bunt]

Best lecture but 1.5x is recommended with better understanding fot last minute preperations !

[@KomalMamHere]

Thank you sir...your explaination is the best

[@BDATTASURYARA]

Sir please step aside at the end of the session so that we can take a screen shot of the code on board clearly.

[@sharath5796]

try writing it ... u can remember easily

[@attitudeboy2840]

Thank you for your explanation sir.,

[@TechnicalKaifOfficial]

Thanks Sir for sharing this one!

[@LousyPainter]

Excellent!

[@dipanz0792]

Great technique sir

[@chahatvamdev4088]

Cool

[@kiranchowdary8100]

Speed 0,25x lo chudandi 😅🤣🤣🤣🤣

[@saikeerthana4809]

😂😂😂😂😂😂😂

[@TYETC156_HARSHALRAHENWAL]

sir what is use of base pointer..?

[@pantaganesh]

sir, i am in dilemma please help me base class pointer in main ????? i think in main void main() { shape * list[2]; triangle t1; rectangle r1; list[0]=&t1; list[1]=&r1; list[0]->area(); list[1]->area(); }

[@rejetimeghavardhan7805]

sir dynamic bining virtual class videos levu sir please sir avi kooda koddiga pettandi sir

[@arghyamandal48]

Can I use two base class pointers in main function, in order to point to two derived classes, while implementing runtime polymorphism?

[@jitho7596]

Yeah...

[@priyankakumaraswamy3953]

#nareshit mee videos anni dhorakatle sir knchm related videos anni okedhagra undelaaga chudandi

[@mmaranta785]

What is the protected for?

[@usharamu2653]

Same doubt

[@allyouinfotech7936]

@@usharamu2653 for furthur inheritance

[@deadpool4765]

sir in this video we didn"t used virtual function .then what is the use of declaring of virtual class

[@saikrishnarudroju5193]

we can use friend function instead of that sir

[@rejetimeghavardhan7805]

no bcoz friend fn is fixed .But here we are using same fn in two different classes to fin triangle area in one and rectangular area in one

[@shrikantpawar3757]

why and when we use abstract class ?can u explain any runtime example

[@omarious]

Purely for inheritance

[@rajubandari1077]

Sir java classes???

[@mainakbhattacharya8457]

Sir you said we can not use same class name more than two times in virtual Function. But in pure virtual Function we are using "class shape" in two times. Why?

[@agastya5194]

Bro. Where did you find virtual function video. I can't get it. Could you please send me the link of that video

[@kalavathidevala4820]

We solve that problem by using virtual keyword . In pure virtual concept shape is a abstract base cls so we can use more than one time ..I think so bro

[@lokeshyadav5183]

What is the basic need to use abstract class

[@064chilukuriaditya3]

For data privacy. (data abstraction)

[@yyndsai]

Why cant we create object of abstract base class

[@kshitijsharma3522]

Sir please help .! When I define the function outside the derived class then the compiler shows the error that function is not a member of above class so sir If I inherited the function from base class then this will be the member of derived class then why it showing such errors ..

[@PainDive1]

#include #include using namespace std; class shape { // abstract base class protected: float d1, d2; public: void getdim() { cin >> d1 >> d2; } virtual float area() = 0; // pure virtual function. }; class triangle : public shape { public: float area() { return 0.5 * d1 * d2; } }; class rectangle : public shape { public: float area() { return d1 * d2; } }; int main() { triangle t; cout

[@abdullahalnoman4249]

kshitji sharma it happens , bcz d1, d1 are declared as protected. Declare them as public...

[@evelynnamugwanya1283]

wonderful!

[@dailygadgets4807]

Where is virtual functions video?

[@ajoydev8876]

Why using pure virtual function??

[@raghavamopidevi9700]

#include using namespace std; class shape { protected: float d1,d2; public: void getdim() { cin>>d1>>d2; } virtual float area()=0; }; class triangle:public shape { public: float area() { return 0.5*d1*d2; } }; class rectangle:public shape { public: float area() { return d1*d2; } }; int main() { triangle t; cout

[@anilkumarpandaga5849]

I can't repay your help

[@nayanshil7849]

O/p kaha hai

[@yashagarwal4388]

op

[@adrielkats6302]
