In C++ Create a function that takes in an array and outputs the min, max and average of the array to a file.
Write a function named repeat_words that takes two string parameters: 1. in_file: the name of an input file that exists before repeat_words is called 2. out_file: the name of an output file that repeat_words creates Assume that the input file is in the current working directory and write the output file to that directory. For each line of the input file, the function repeat_words should write to the output file all of the words that appear more than once on that line. Each word should be lower cased and stripped of leading and trailing punctuation. Each repeated word on a line should be written to the corresponding line of the output file only once, regardless of the number of times the word is repeated. For example, if the following is the content of the file catInTheHat.txt: Too wet to go out and too cold to play ball. So we sat in the house. We did nothing at all. So all we could do was to Sit! Sit! Sit! Sit! The following function call: inF = 'catInTheHat.txt' outF =…

Write a function definition called, sigma, that takes an input file reference and two integer references as its parameters. The function should read the numbers from a file, calculate their total value (cumulative sum), find the largest, and smallest numbers in the file. The function should return the cumulative sum, the largest, and the smallest values to the calling function. Note: the function reads the entire file.

Examine the following three functions that take as argument a file name and return the extension of that file. For instance, if the file name is 'myfile.tar.gz' the returned value of the function should be 'gz'. If the file name has no extention, i.e. when the file name is just 'myfile', the function should return an empty string. def get_extension1(filename): return(filename.split(".")[-1]) def get_extension2(filename): import os.path return(os.path.splitext(filename)[1]) def get_extension3(filename): return filename[filename.rfind('.'):][1:] Which of the these functions are doing exactly what they are supposed to do according to the description above? get_extension3 only get_extension2 only None of them. get_extension1 only
