Write an interactive C program that reads a series of 12 temperatures from a file called "12temp.dat". It should display to the user each temperature and the difference between the current temperature and the one preceding it via cout. The difference is not output for the first temperature that is input. At the end of the program the average temperature should be displayed. For example given the following input data:

34.5 38.6 42.4 46.8 51.3 63.1 60.2 55.9 60.3 56.7 50.3 42.2

34.5
38.6 4.1
42.4 3.8
46.8 4.4
51.3 4.5
63.1 11.8
60.2 -2.9
55.9 -4.3
60.3 4.4
56.7 -3.6
50.3 -6.4
42.2 -8.1
