C pointers and the physical address

Question

I\'m just starting C. I have read about pointers in various books/tutorials and I understand the basics. But one thing I haven\'t seen explained is what are the numbers.

Answer 1

It's the address or location of the memory to which the pointer refers. However, it's best if you regard this as an opaque quantity - you are never interested in the actual value of the pointer, only that to which it refers.

How the address then relates to physical memory is a service that the system provides and actually varies across systems.
