What this means is that this file contains 12 words, with a comma separating each of the words. You will not know how many words are in the file, until you open and process the file. In fact, one of the files will have over 180,000 words in it.

Your task is to read the file into a dynamically created array. After the file is completely stored, pass that array to a subroutine or subroutines that will find the word or words that have the most vowels (use a, e, i, o, u as vowels), and return that word or those words to the calling program in a dynamically created array that is returned (not passed by reference), to the calling program. The calling program will then print those word(s) and the number of vowels that each has.

You must use defensive coding, there may be more or less words in the file than the first number given. If there are more words in the file than the number of words given at the beginning of the file, stop processing the file when the number of words exceeds what was given at the front of the file. If there are less words than the number of words at the beginning of the file, stop processing when you run out of words.

Remember that any dynamically created arrays must be properly deleted before the program closes.

You may use the string class or c-strings to complete this assignment.

The program must be well documented. Please include a text file of your program processing the three example files, with a file name of lab04XXX.txt, where the XXX is your initials.

Hint: the getline( ) function makes it easy to process comma delimited material, see section 12.5 of your text for an example.

Here are the three example word files. The files the grader will test your program on will be different in size, but be in the same file format. I suggest you test with the first file and after that works properly test with the larger files.

• lab05Small.dat
• lab05Medium.dat
• lab05Large.dat

Provide a user interface that allows the user to add additional words to the array. The user must be able to add one or more words to the array from the keyboard (use a loop).

After the user adds the word, call a function that takes the existing array, adds the new word to the array, and then returns the expanded array. The function prototype for the function should be: void addWord(string * saWords, int & iSize, string sNewWord) The string pointer will be used to receive the existing array and then after modification pass back the new array. The size must be passed by reference, to allow the function to increase the size of the array. Remember to do this, the following steps are required:

• Dynamically create the new array of the proper size (one larger than the current array)
• Copy the old array into the newly created array
• Add the new word into the array as the last word
• Delete the old array
• Increment the size of the array

You should then call the function that finds the word with the most vowels and output the results. The user should then be asked if they want to add another word to the array.

• Your Name
• Purpose of this program.
• Program source code
• Program output, using the small sample data set given above. You need to demonstrate adding three additional words, one of which will have the most vowells of any of the words.
• Pseudocode for the program, including the functions.
• How was this program tested, including the test cases you used to verify the program worked properly.
• What problems/successes did you have with this program?
• An estimate of how much time you spent working on this assignment
