Part 1

Stars can be classified into color groups called spectral classes. Stars can also be classified by their magnitude, which measures their brightness. The lower the magnitude, the brighter the star. Magnitudes can range from -7 to 15. The table below lists some common brightest stars and their distance from Earth in light-years. Write a CLIPS program that asks the user for the spectral class and the magnitude of a star. The program should then list all stars matching both the spectral class and the magnitude with their distance from Earth in light-years.

Part 2

Once you have Part 1 working, add a new feature. If no star is found that matches both spectral class and magnitude, list all stars having the specified spectral class, followed by all stars having the specified magnitude. Label each section of output accordingly.

Hint for development:

Because an expert system is not modular or object-oriented, testing cannot be done in the manner you have learned in other classes. If you write the entire program and try to run it, errors will be difficult to locate. Since Part 2 has 2 distinct phases, get each phase working before proceeding to the next phase. It is advisable to context limiting for each of the components in Part 2.

Part 3 

If you have everything working in Parts 1 and 2 but find yourself still wanting more, you can take the challenge. Spectral classes correspond to temperature ranges for the stars as in the table below:

Allow the user to enter the star’s temperature rather than spectral class. Use the temperature to determine the spectral class and proceed with listing the stars as in the previous sections.
