Virtual Memory or Physical Memory

Question

Suppose we write a program in C and print the address of one of the variables declared in the program, is the address that gets printed on the screen the virtual address or the

Answer 1

It will be a 32 bit virtual address in most cases.

If your OS supports does paging then it would be the virtual address. It could have been mapped to the same physical address using paging. Linux and Windows do paging.

Another thing that matters is the architecture. On Intel x86 32bit system it will be 32 bit address. The first 10 bits of the address will be used to get page table. The second 10 bits will be used to get page from the selected page table. And the last 12 bits will give you the actual physical address from that page.

I hope it answers your question.
