In thiis video we will learn about virtual destructor in C++.
NOTES:
1. If we delete child class object through a pointer of parent class then it is undefined behaviour,
if parent class doesn't have virtual destructor.
2. If we fail to declare destructor as virtual in parent class then we endup having memory leak.

where is that video of virtual pointer and virtual table in c++, i can not found ?

[@marativamshikumar3489]

Hi Rupesh, one ☝️ kind request. Please make a video on vtable, vpointer and virtual internals.

[@CppNuts]

Sure dude..

[@kanishkjain2767]

You still haven't posted the video for vptr and vtable
Please post that
I am having trouble understanding those concepts from another videos

[@prishaphotography9063]

Nice video

[@CppNuts]

Thanks

[@dhirajbennadi7850]

Is it safe to make the destructor of the base class as virtual? If there is a statement delete this in the destructor of the base class would it not cause an issue??

[@sivaramakrishnachitithoti1428]

Thanks

[@CppNuts]

Welcome

[@arunchoudhary7493]

You have cleared the concept thansks :), in the end of the video you mentioned about the virtual pointer and virtual table, Where is that video, you posted that video?

[@CppNuts]

Not yet.

[@arunchoudhary7493]

@@CppNuts is there a plan to create that video, if yes, when can i expect that.
Thanks in advance.

[@prabhakaranraja8346]

@@CppNuts Is there any plan to release the virtual pointer and virtual table video ?

[@CppNuts]

@@prabhakaranraja8346 Yes in few days..

[@KNT_19]

Is virtual destructor also added to the vtable like other normal virtual functions?

[@CppNuts]

No it's not.

[@udayachandran8541]

where is the link for vptr and vtable?

[@raghuj7097]

Sir, pls share internals of virtual functions, vtables , vptrs

[@CppNuts]

Sure..

[@CppNuts]

I switched from windows to mac and those commands stopped working in mac, somehow i need to record this video on windows machine, which is kind of problematic because i don’t have windows machine.

[@madhuriagawane3071]

next video of vptr and vtable?

[@CppNuts]

It's ready, need time to record it.
May be in 2 to 3 days.

Your computer is using 32 bit processor ?

[@user-tz9kn1nu3u]

why don't you just make a makefile which could compile and run code for you?
That could save you unnecessary typing.

[@CppNuts]

Thanks man..
