  11. Problem: Program will ask user to input file name.
  12.          Program must open the file for each city to receive the average carbon footprint for the city. 
  13.          Program will then compute the fine that the city must pay according to their average carbon footprint.

  16. Part 1: Data Input
  17. Item            Variable            Data Type           Remarks
  18. Data File Name	DataFile            string		input
  19. dataFile	flagdataFile	    flag		true or false
  20. OutputName	outputFile	    string		output
  21. City Name	cityName	    string		
  22. Carbon Numbers	oneCarbon	    int		
  23. Counter		numTests	    int	
  24. Fine		fine		    double
  25. Average		Average Carbon	    double
  26. Rounded Average	roundedAverage	    double		double rounded	
  27.  
  28. Part 2: Data Ouput
  29. 1. Greet User
  30. 2. Ask User to input file name
  31. 3. Ask User to input the output file name
  32. 4. Output City Name, Rounded Carbon Average, and Fine corresponding to the data input.
  33. 5. If Error, output corresponding error message only.
  34.  
  35. Part 3: Analysis
  36. declare oneCarbon from input file
  37. sum += oneCarbon
  38. averageCarbon = static_cast<double>(sum) / numTests;
  39. roundedAvgCarbon = round(averageCarbon);
  40.  
  41. Part 4: Algorithm
  42. 1. Input all of the required #include and using namespace std.
  43. 2. Greet the user and explain what the program is going to do.
  44. 3. Ask the user to input file name.
  45. 4. Check the file to make sure that it is not empty or have any negative values.
  46.    If input is invalid, print "Invalid Input."
  47.    If input is valid, compute the fine according to the data.
  48. 5. Ouput Closing Statement "THank you for using El Camino's Carbon Footprint Program"
