Rajkumar its really nice question for studying c-lang:
ans is: u know that whenever u declare a variable in c, its gets a junk value,unless it is global variable..same happens with pointer...so if u change the contents of that pointer it will effect the memory which is somewhere which doesnt belongs to u..
so this pointer with garbage value is known as dangling pointer.

When two pointers point at the same address, and one pointer free that address, i.e, the memory location is emptied, the other pointer still points to the same location. such a pointer pointing to a deleted location is called a dangling pointer.

A pointer that points to some area of memory you may or may not be using. Often it is the result of unitializing a pointer, or not nulling a pointer after it's useful purposes.
