H Conclusion Pointer.
To pointer is a very powerful
Flexible tool in C and C programming. By using a pointer to a pointer the pointer itself can be indirectly accessed and modified thereby implementing more India Phone Number complex data structures and memory management operations. Whether in dynamic memory allocation function parameter passing or in implementing data structures such as linked.
