Building Entrance Tracker Due to Covid-19, we can allow only 5 guests to our building at a time. Our task is to write a program that helps the entrance staff to keep track of guest entries to the building. Feature 1 (40 points): Each guest must sign in upon entry into the building. If the number of guests currently in the building is already at the limit of 5 persons, inform the guest that he/she cannot enter. Otherwise, allow entrance and record the name of the guest to the system. Feature 2 (40 points): Each guest must sign out upon exiting the building. At sign-out, the guest enters his/her name. If the name is not in the system inform the guest that this name is not in the building. Otherwise, ask the guest to input how long (in minutes) he/she spent in the building. Remove the name of the guest from the system, and record the time spent. Feature 3 (40 points): When asked for a report, the system should display the number of people currently in the building along with the names of those people. It should also report the average number of minutes our guests spend in the building. Feature 0 (30 points): When we ask to exit the program, we should be prompted with a warning if there are still guests in the building. Upon confirmation, users can still quit the program. Make sure to include minimum 3-4 comments in your source code.
