Need to understand the overloaded assignment operator behavior

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?

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.
