Basic thing, copy constructor will be called whenever a copy
is made. and copy constructors are called when:
1. create a new object using existing object.
2. When is returning to caller.
3. When an object is passed by value as a parameter to a
function
Basically a default copy constructor will be created which
does bitwise copy also know as shallow copy.
This will become a problem when we are dealing with dynamic
memory allocation for variables and leads to dangling pointer.
To overcome we have to override by deep copy.
