Please make it so I can find the average ,minimum and the maximum temperature in celsius

Assume that, for a given town, mid-day daily temperature in Fahrenheit was measured for two weeks and stored in a file called temprature.txt. Write a complete C Language program that reads the stored temperatures, one at a time, from the file temprature.txt and converts the read temperature to its equivalent in Celsius. Your program should store each converted temperature in an output file called results.txt. Your program should also find the average, the minimum, and the maximum temperatures in Celsius and saves the results in the output file. Use data type double for input and output temperatures
