**Please help

*** In C programming. The program will take 3 arguments (in order) - choice infile outfile If the choice is 1, implement the "copy" function that will read the infile, covert the content to all upper cases, and save the result to the outfile. The outfile format should be the same as the infile. If the choice is 2, implement the "sort" function that will read the infile, sort the content by decedent order (a-z), and save the first 10 characters for each line to outfile. The outfile format should be the same as the infile. If the choice is 3, implement the "wc" that will read the infile, count and display the number of words, number of lines, save the result to outfile. You need to handle the following situations and stop the program when they happen. If the number of command-line argument is not 3, print the help manual about how to run the program. If the choice is not 1, 2 or 3, print an error message "Wrong choice, the only available values are 1, 2, 3". If the infile is not found, display an error message "Error! No such file - infile" If the outfile cannot be written, display an error message "Error! Cannot save file - outfile". *** In C programming.
