INTRODUCTION:

You are working on development of a new power plant for Centerville, USA. Average monthly temperature data has been collected as part of designing the new power plant, and you are required to develop a computer program that will perform averaging analysis. The input data file is called temp. 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 temperatures: 12 rows (January December) and 5 years (2012 2016).

ASSIGNMENT:

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 temperatures are store in a two-dimensional array. Manipulate the two-dimensional array to calculate the average temperature for each year and the standard deviation in temperature for each year. Then find the minimum and maximum temperatures and the locations in the array of the minimum and maximum values.

The formula for standard deviation is:

s= (((x-x )^2 ) / (n-1))

where s is the standard deviation, x is the individual sample values, x is the mean value, 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 temperature.

Print the output to the computer screen and to an output file called temp_report. Illustrated below is the output style for the computer screen and the output file.
