Can a destructor take arguments?

Short answer. No.

What is the destruction order?

Last made, first destroyed.

Remember

~ClassName, no arguments
Runs when object dies
Reverse order

Two objects end together. Which one dies first? The destructor has a tilde. A is made first, then B. At the brace, B dies first. So it prints B A. Tilde and the class name. It runs when the object dies. Last made, first destroyed.
