Was asked to design Entities involved and their communications, basic algorithm, data-storage logic if any. As you know, every OS comes up with this tiny application called the calculator. It is good. Now, here is our problem. If we try to implement the function. I have to write if upon if upon if upon if to do for all operators. Moreover, some operators are not even binary! Take example the abs or say the negate! Bigger problem persists. With the if mode, we can not even add operators as we wish to without changing code!
But that is a sin. So, what do we do?
