hi all. can anyone give the source code for shallow copying?

Shallow copy usually means copying a pointer, rather than the underlying data; this means changes to the copied object will be reflected in the original. You can probably supply your own "source code" now.

In c++ there is default copy constructer or assingment operator. it using shallow copying. so it is the default one.for deep copy only we want the coding.

The default behaviour is to copy! Deep and shallow are just programming concepts. The notion of shallow copying comes from the fact that if you copy a pointer you are copying a memory address; as such your copied object contains a pointer that points at the same place as your original object's pointer.

In essence "shallow copy" means to copy a pointer directly rather than constructing a copied pointer via new.
