Exercise #1

Complete the following constructor Planet(): You must finish the declaration of the default constructor.

For example:

Test	Result
Planet p3; cout << p3.toString() << endl;	{Name: KNOWHERE,Population: 0, Habitable: False, Diameter: 8975.000000, Water: True, Closest Planet: XANDAR, Galaxy: GUARDIANS}

Answer:(penalty regime: 0 %)

NOTE: Remember to constantly verify the Planet class to see if there anything that can help with the solution.
