Write a C program that inputs a file of measured_data_t records and determines the site with the greatest variation in temperature (defined here as the biggest difference between extrema) and the site with the highest average wind speed for all the days in the file. You may assume that there will be at most ten sites.

Test the program on the following July daily data collected over one week at three sites:

 ID        Day    Wind Speed (knots)    Temperature (deg C)
2001      10               11                         30
