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

That's a virtual address of anumber variable. Every program has its own memory space and that memory space is mapped to the physical memory. The mapping id done by the processor and the service data used for that is maintained by the operating system. So your program never knows where it is in the physical memory.
