Counting the occurrence of words in a file - c

Question

My wordOccurrences don't work if you read a file. They can appear twice in the counting so it doesn't count correctly but if I input from stdin it counts correctly.
So I have to read in a file (-i input.txt) count the words and word occurrences in that file. Output the results in the specific file that is given with -o output.txt. If there is a -c it should ignore punctuation and convert to lowercase
