Part 1: Daily Averages Consider the small input sample below.
Please write c code.
Part 1: Daily Averages Consider the small input sample below 3 11 12 05 1 8.7 3 11 11 56 143 8.6 3 11 13 01 163 8.9 3 10 18 05 1 7.3 3 10 19 01 1 7.3 2 28 01 02 2 -1.0 2 28 09 07 2-0.5 6 10 17 00 111 18.7 Notice that there are observations present for 4 different days (March 11th, March 10th, Feb. 28th and June 10th) Your task for part 1 is to write a program which reads an input file containing any number of observations and generates an output file called daily_averages_summary.txt containing the average temperature for each month/day in the input file The output will be a text file with one line for each month/day in the input file. Each line will have the format "month day average temperature", where temperature is printed with two decimal places (using the %.2f, specifier). The output must be printed ordered by month and day Days for which no observations were recorded must be omitted from the output. For example, on the input sample above, the output would be 2 28 -0.75 3 10 7.30 3 11 8.73 6 10 18.70Explanation / Answer
