    A pointer points to some specific location in memory.
    Eg : 'a' is a pointer pointing to a memory address 4000 which is containing some data.
    After we delete the data which was at address 4000,it actually means address 4000 in memory is now a part of free memory pool which can be used for reallocation of some data.But a is still pointing to address 4000.In this case 'a' is a dangling pointer.

    To avoid the problem of dangling pointer after freeing memory address,we should point it to NULL.
