Lowest and highest memory address in c?

Question

Is there a way to print the lowest and highest memory address that the operating system can address in c?

Answer 1

No, this is not a hallmark of standard C. No matter what solution you need, you will need to specify the OS.

If you have a specific OS, keep this in mind. But it's hard for me to wonder why this matters. There was no need to write C programs, so perhaps you could enlighten us.

Based on your comment:

I'm curious, "if every process gets an address space in memory, can I print the top address and bottom address of this process?"
