Pointers lay the foundation of C programming, offering direct memory access and manipulation capabilities that are both powerful and complex. As we delve deeper into pointers, we encounter double pointers, an extension of the basic pointer concept. Do
the pointer in the caller remains unchanged. 4.9 Suppose I want to write a function that takes a generic pointer as an argument and I want to simulate passing it by reference. Can I give the formal parameter type void **, and do something like this?
