I understand your point
Corona688, but I am still unable to figure out the answer to my question
, that is why the class A's assignment operator is invoked when instance of B is assigned when class A and B has no inheritance relation between them except containment object?
Also, I noticed that suppose if there is any other containment object, say "C c" data member available inside class B and if class C is having an assignment operator overloaded function implemented then during the b = b; both A's and C's version of assignment operator functions will be called according to the order of data member in class B. So is there a rule like, when there is a container object then that class's overloaded assignment operator function should be invoked when there is none present in the calling class's object?

Detailed Description
template<class _Tp>class std::gslice_array< _Tp >
Reference to multi-dimensional subset of an array.
A gslice_array is a reference to the actual elements of an array specified by a gslice. The way to get a gslice_array is to call
operator[](gslice) on a valarray. The returned gslice_array then permits carrying operations out on the referenced subset of elements in
the original valarray. For example, operator+=(valarray) will add values to the subset of elements in the underlying valarray this
gslice_array refers to.
Parameters:
Tp Element type.
Definition at line 82 of file valarray.
