In other words, how does the implementation keeps track of the count?
Is there a map-like object maintained which is accessible by all the shared_ptr instances whose key is the pointer's address and value is the number of references? If I've to implement...

Creating a memory leak with reference-counting smart than one object at a time.
When you make copy of shared_ptr object it copy pointer with count of references, increase it, and copy pointer on contained object.

I was better at counting calories than points because there was less converting.
People seem more successful counting points.
The only calorie counting I might do is at dinner/snack.

In purely functional languages, data is immutable. With reference counting, creating a reference cycle requires changing already created data. It seems like purely functional languages could use reference counting without worrying about the possibility...

I'm not saying a ref counting mechanism is impossible with a circular.
And GC most of the time with the possibility of circular references .
Reference counting is MUCH slower than GC because it's not good for CPU.

Modern ATL/MFC applications now have access to a new shared pointer class called CAutoPtr, and associated containers (CAutoPtrArray, CAutoPtrList, etc.).
Does the CAutoPtr class implement reference counting?

Using boost::shared.
Having checked the CAutoPtr source, no, reference counting is not supported.

I come to know that when many objects shares same data and creation and desturction of objects are expensive then one can go for reference counting .
Can anybody give input about how to achieve it for the library class which cant be changed ?.

RAII = Resource Acuquisation is Initialitazation Ref Counting = "poor man's GC"
Together, they are quite powerful (like a ref-counted 3D object holding a VBO, which it throws frees when it's destructor is called).
