One doubt in distructor

#1

Here in destructor why we are checking that if arr!=NULL then delete arr…

#2

Hey @ashishnnnnn
you can directly delete it as well because
Deleting a null pointer has no effect.
Its completely your choice

#3

What if we don’t use distructor in our class???

#4

Then also it will work but its a good practice to deallocate memory when its out of use.

#5

Yaa… I wanted to make sure, that we are using distructor to delete the heap memory… as there will be no wastage of memory.
Thanks…
