Hi,
Can a self referential pointer exist in C? How do we use it and what are its applications?

    :
    I think you mean self referential structures, not pointers.
    In fact, a structure cannot contain an instance of itself, but a pointer to an instance of itself. eg:
    [code]
    struct node
    {
    int data;
    struct node *left,*right;
    };
    [/code]

    used for binary trees.
