Please code using the C language (NOT C++) and please include comments. Thank you in advance.

Description For this homework, you will be making a command line utility, columnSorter. This program will require one command line parameter, the number of a column. This program will read input data on stdin, saving each line it reads in a list. It will then sort the list based on the values in the indicated column, then it will write all of the data out to stdout. The input data should be in the form of CSV (comma-separated-value). Each line can be divided into a number of columns, being split at commas. We have a couple of simplifications here, just to make this problem a little more manageable: 1. Every line has the same number of columns 2. All of the entries are simple values, integers or words. The text values aren't quoted, and there are no commas inside a value. Here is a short example of some input: Sam,15,banana Julie, 23,grape Scott, 12,kiwi If the program was asked to sort by column 1 (the names), the output would be: Julie,23,grape Sam, 15,banana Scott, 12, kiwi but if the program was asked to sort by column 2 (the numbers), the output would be: Scott, 12,kiwi Sam, 15,banana Julie 23, grape Your program should use at least one structure, and should have at least a couple of functions
