This program will convert a set of temperatures from Fahrenheit to Celsius. 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 temperatures in Fahrenheit. You need to display all of the values from the first temperature to the last temperature. You increment from one temperature to the next by the increment value (the third value you read in). You need to convert these temperatures to Celsius. You need to output the temperatures as both Fahrenheit and Celsius. The numbers should be 15 characters wide with 3 digits of precision and need to be in fixed format. Do not use tab characters (t) to output the values For part 2 you MUST have at least 4 functions, including main. The main function will be the driver of the program. It needs to either do the processing or delegate the work to other functions Obviously the main function will have the same function that you have been using for all of your labs. In addition to need to have a function with the following signature: double convert (double fahrenheit) Other functions that you may want to have are A function to read in the values A display function . A display heading function The headings are also required (see the sample output below) The conversion from Fahrenheit to Celsius is celsius - (fahrenheit -32)/1.8 Here is a sample run with valid input: 30 100 20 The output would be Celsius 34.444 23.333 12.222 Fahrenheit 30.000 10.000 10.000 30.000 50.000 70.00 90.000 10.000 21.111 32.222 For data validation you need to make sure the first number read in is less than or equal to the second number. The third number read in must be greater than 0. If this is not the case you need to output the following message and read in three new values
