You are working on development of a new water treatment plant for Spokane, Washington. Monthly rainfall data has been collected as part of designing the new water treatment plant, and you are required to develop a computer program that will perform statistical analysis. The input data file is called rainfall. As you examine the input file, you notice that the first record line is the name of the city and type of data, the second record line contains the control numbers, and the remaining record lines are the average monthly rainfall amounts: 12 rows (January – December) and 6 years (2015 – 2020). Write a C program that will read the data from the input file, such that the city name and type of data are stored in a one-dimensional character array, and the rainfall amounts are stored in a two-dimensional array. Manipulate the two-dimensional array to calculate the average rainfall for each year and the standard deviation in rainfall for each year. Then find the minimum and maximum rainfall and the locations in the array of the minimum and maximum values. The formula for standard deviation is:

Manipulate the two-dimensional array to calculate the average rainfall for each year and the standard deviation in rainfall for each year. Then find the minimum and maximum rainfall and the locations in the array of the minimum and maximum values.
The formula for standard deviation is:
s= (x-x)2n-1
where s is the standard deviation, x is the individual sample values, x is the mean value, Σ is the summation, and n-1 is the number of values in the sample minus 1. In this case, n is 12 (number of months in the year) and x is the yearly average rainfall.
Print the output to the computer screen and to an output file called rain_report. Illustrated below is the output style for the computer screen and the output file.
