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. In a number of machines top two elements of stack and top of stack pointer is kept in CPU registers whereas the rest of elements may exist in memory.
