C program to demonstrate example of double pointer (pointer to pointer)
In this program, we have to declare, assign and access a double pointer (pointer to pointer) in C.
As we know that, pointers are the special type of variables that are used to store the address of another variable.
But, when we need to store the address of a pointer variable, we cannot assign it in a pointer variable. To store address of a pointer variable, we use a double pointer which is also known as pointer to pointer.
