revise the client program $($main$.$cpp$)$ to test the other operators.$$ They are $--($pre and post decrement$),-($subtract Note: need to check for negative results and error if that is the case$),$ the insertion operator $(>>$ get dimensions from the terminal operator$),$ and the other five comparison operators and $>).$
