Compare zero$-,$ one$-,$ two$-,$ and three$-$address machines by writing programs to compute the below expression for

each of the four machines $-$

For the one$-$address instruction. a second address must be implicit. This was common in earlier machines,

with the implied address being a processor register known as the accumulator $($AC$).$ The accumulator

contains one of the operands and is used to store the result.

Zero$-$address instructions are applicable to a special memory organization called a stack. The zero$-$address

instructions would reference the top two stack elements.

The instructions available for use are as follows:
