Question

Before you start doing this code

Read carefully there is a format that you have to follow

Instructions: This program will generate some information for a user about interplanetary travel (pretend we can travel easily to other planets for this problem). This program will perform calculations concerning weight on various planets as well as travel time between planets. (Do not use arrays for this program - make the program as efficient as possible using only selection statements) Your program should start out by displaying the following information about the program: Welcome to INTERPLANETARY TRAVEL PROGRAM: This program enables you to find out your travel time to the planet you want to travel to as well as your weight on there. Please enjoy the program and hope you'll find the perfect planet for you! Next the program should display the following menu:

HERE IS THE FORMAT YOU MUST USE FOR HW #2 - NOTE THE IF ELSE IF...not IF IF IF

HW #2 Format :
