Your task is to write a computer program that lets the user create a database of access roads and trails to assist with the ongoing maintenance of the forest. For simplicity, we will use the term track to refer to either an access road or a trail. Each track will have the following:

  • Type: Whether the track is a walking trail, a bike trail, a horse trail, or an access road

  • Name: Not all trails and access roads are named, though some are

  • Direction: Some trails and access roads are one-way, while others can be travelled in both directions

  • Status: Whether the track is currently open or closed

Since the recreational forest is continually being developed, new tracks are being regularly added, while existing tracks are sometimes modified or even removed...
