Printf("%d\n",sizeof(volatile)); Printf("%d\n",sizeof(constant));Printf("%d\n",sizeof(unsigned)); Printf("%d\n",sizeof(signed));

Question

What are the answers for this?

Answer 1

Why not paste the snippet on a new C code, then run it in Code Playground to see the result.

Some notes:
* `sizeof` returns an unsigned long long (64bit integer) use of %d is rather inappropriate.
* `constant` is not recognized as a type from which you can do size test.
* `Printf` should've been `printf`, a minor typo, but will still prevent the code from running.
