7. (20 pts) Write a C++ application, in the file wordcount.cpp that reads standard input and displays a word count table to standard output. Normalize and lowercase the file text. Sort the output by number of occurrences descending. For example, if the input file is: The tests, my lord, have failed! FAILED have the tests, they have. then your program should output have 3 failed 2 tests 2 the 2 lord 1 my 1 they 1 "Words" are made up of Unicode letters only. Every other character is ignored. Use whatever wonderful functions you can find from the standard library.
