Create a program that stores your plans for a week. Each plan needs a start- and an end-time, given to the nearest whole minute. You should choose between loading a plan, adding information to a plan, showing the current plan, and saving the current plan. The plan should be saved in a file, so you can load it again later with the same program. When showing the plan, you should only print the non-empty time-slots. Example use: *Choose: load, add, show, save, exit Choose from the list: add Which day? Thursday Start-time? 10:30 End-time? 12:15 What is the plan?
