I have a text file to be read "Mary had a little lamb its fleece was white as snow and everywhere that Mary went, the lamb was sure to go!".
The program should do the following:
1. count number of words in file
2. print all words, one per line
3. ask user if they want to change any words. if yes, then needs to ask user what word they want to change and what they want to replace it with. then execute a replacement.
4. output words with the replacement, if applicable.
5. output words by their length, and then output words alphabetically (all words one per line)
This is what I have so far, but there are many errors but I dont know how to fix it. Can anyone help?
