One thing that is already causing problems and is sure to cause more problems in the future is changing cables. USB C is the most widely used cable for a variety of items. Although it is widely used there are so many different port types and needs for each port. I-phones changing from lightning to USB c is very problematic for people who have bought many lightning cables. These cables will now have no purpose. All these years spent collecting these cables will have been for nothing. It will also be problematic for people who are selling the cables. They won’t know how many cables to sell and which types for each. The extra stock of lightning cables will be wasted. There is no solution to this problem as it is a transition that must happen. But this is nonetheless going to be problematic for people around the world who have invested in electronics.

In my app development I have almost completely completed my calculator. I have spent a long amount of time on it. The effort I have put in has been extreme. I have completed all parts of the application except for the percentage sign as well as the negative/positive sign. Other than that I have perfected the calculator app. That’s all I have to write for now
