1. Programming Problem 4 in Chapter 5 asked you write a C+t progra user to enter his or her weight and the name of a planet. In Problem 2 asked you to rewrite the program using a Switch st the program so it uses an enumerated type to represent the Chapter 7, Programming rewrite is repeated here. The planetNOw, For ease of reference, the information for the original prob eight must be multiplied for each planet. following table gives the factor by which the weight must be m The program should output an error message if the user doesn't input a corn name. The prompt and the error message should make it clear to the user how name must be entered. Be sure to use proper formatting and appropriate comment your code. The output should be labeled clearly and formatted neatly correct pla net Mercury 0.4155 Venus 0.8975 Earth 1.0 Moon 0.166 Mars 0.3507 Jupiter 2.5374 Saturn 1.0677 Uranus 0.8947 Neptune 1.1794 Pluto0.0899
