Answer Posted / som shekhar
If we are deriving from the base class and the base class
consist of some virtual function , then in this case the
base destructor should be virtual.
if you do some thing like this :
base* b = new derived;
delete b;
In this case if base destructor is NOT VIRTUAL then only
base destructor is called and derived destructor wont be
called resulting into memory leak.
But if the base destructor is virtual then derived class
destructor and base destructor both will be called.
