Question

Write a C++ program that reads daily weather observation data from a file and writes monthly and annual summaries of the daily data to a file.

a. The daily weather data will be contained in a file named wx_data.txt, with each line of the file representing the weather data for a single day.

b. For each day, the date, precipitation amount, maximum temperature, and minimum temperature will be provided as tab-separated data with the following format: 20180101 0.02 37 23 20180102 0.00 42 18 <...data for the remainder of the year here...>

c. For the first entry in the daily data above, the date is 20180101 (1 January 2018), the precipitation amount is 0.02 inches, the maximum temperature is 37°F, and the minimum temperature is 23°F.

d. You may assume that the weather data is complete (i.e., there is data for each day of every month of the year) and that the data contains no errors.

2. The program must read from file each daily weather observation and write a summary by month and year to a file named wx_summary.txt.

a. The output that is written to file must have the following format:
