Alt Fn Ctri Part A: Ask the user to keep entering words as long as the user does not write "stop". Record the user input as a string or array element (your choice) by appending them to the current variable. (Hint: use +operator for appending to strings) Note: Make sure to include the user-entered "exit" in your analysis for Part B Note: Using Arrays will get you 10 points of extra credit if done correctly Part B: Once the user enters "exit", then the program should display the following menu: A. Display the total number of words entered by the user B. Display all the words entered by the user C. Display the total number of times the letter ”e" occurs D. Display the total number of words with more the one e" occurrence E. Display all the words in lowercase F. Display all words in uppercase G. Display if a certain word was entered by the user H. Exit Print a goodbye statement for the user to indicate the end of the program. Option Details: Option A; Displays the total number of words entered. Option B: Displays all the words the user entered. Option C: Displays the total number of times the letter e" occurs in all of the words entered Option D: Displays the total number of words with more the one "e" occurrence Option E: Displays all the words in lowercase. Option F: Displays all the words in uppercase. Option G: Asks the user to enter a word and then display if it the word was entered previously or not. Option H: Exits the Program The program should only exit when the user chooses to exit using this option. Note: Remember to include input validation! If the user, enters an option that is not valid (A-H) it should be handled accordingly.
