How to do it...

1. Create an abstract class called Shuttle and give it a member called TWR, which is the calculation of the TWR of the shuttle:

        public abstract class Shuttle         {           public abstract double TWR();         }

2. Next, create a class called NasaShuttle and have it inherit from the abstract class Shuttle by putting the abstract class name after a colon at the end of the NasaShuttle class declaration:

        public class NasaShuttle : Shuttle         {         }

3. Visual Studio will underline the NasaShuttle class because you have told the compiler that the class inherits from an abstract class, but you have not yet implemented the members of that abstract class:

4. To fix the issues identified, type Ctrl + . (control key and period) and let Visual Studio show ...
