Q. What is Stack Addressing?
In this addressing technique operand is implied as top of stack. It isn't explicit however implied. It employs a CPU Register known as Stack Pointer (SP). SP points to the top of stack which means to the memory location where last value was pushed. A stack offers a sort-of indirect addressing and indexed addressing. This isn't a very common addressing technique. The operand is found on top of a stack.
