Rover Control Center

Welcome to SPACE: Space Program for Aeronautical Collection and Exploration. You are in charge of the Rover Control Center. All rovers on Moon and Mars are under your direction!

This project will show you some ways in which references, inheritance, interfaces, and arrays can help you be a better C# programmer.

When you start this project you don’t need to read through the class definitions. In fact, the project will tell you when you need to look. To start, all you need to know is that MarsRover and MoonRover inherit from Rover:

class MoonRover : Rover

class MarsRover : Rover

IDirectable.cs

namespace RoverControlCenter
{
  interface IDirectable
  {
    public string GetInfo();
    public string Explore();
    public string Collect();
  }
}

Program.cs

using System;

namespace RoverControlCenter
{
  class Program
  {
    static void Main(string[] args)
    {
      MoonRover lunokhod = new MoonRover("Lunokhod 1", 1970);
      MoonRover apollo = new MoonRover("Apollo 15", 1971);
      MarsRover sojourner = new MarsRover("Sojourner", 1997);
      Satellite sputnik = new Satellite("Sputnik", 1957); 
      Rover[] rovers = { lunokhod, apollo, sojourner };
      DirectAll(rovers);
      Object[] probes = { lunokhod, apollo, sojourner, sputnik };
      TrackProbes(probes);
      IDirectable[] directables = { lunokhod, apollo, sojourner, sputnik };
      DirectAll(directables);
    }

    static void DirectAll(IDirectable[] rovers) 
    {
        foreach (IDirectable rover in rovers)
        {
          Console.WriteLine(rover.GetInfo());
          Console.WriteLine(rover.Explore());
          Console.WriteLine(rover.Collect());
        }
    }
