General overview This program will convert a set of temperatures from Fahrenheit to Celsius and Kelvin. Your program will be reading in three double values. The first values are starting and ending temperatures. The third value is the increment value. There is no prompt for the input. There is an error message that can be displayed. This is discussed later. You need to display output for all of the values between the starting and ending values. First two values are...
