$(1)$ Write the function containsWord $(5$ pt$)$

$($a$)$ Place a prototype above main$()$ under the comment

$//$ Add the remaining three function prototypes here

int containsWord$($vector words, string word$)$;

$($b$)$ Write a definition for this function below main$()$ under the appropriate comment

$($c$)$ This function should return the index of where word is located in the vector words.

If word is not in the vector words, the function should return $-1.$

$($d$)$ Test $1$ will test the function. You can submit after writing the function to see if it works correctly. You do not need to finish main first.

$(2)$ Write the function processInputFile $(5$ pt$)$

$($a$)$ Place a prototype above main$()$ under the comment

$//$ Add the remaining three function prototypes here

void processInputFile$($vector& words, vector& wordCount, ifstream& file$)$;

$($b$)$ Write a definition for this function below main$()$ under the appropriate comment

$($c$)$ This function should read through the already opened file one word at a time.

i$)$ Each word read in should be pre$-$processed. For each word remove the punctuation from the word and make all the alphabetic characters lower case. You have been provided with two functions to help you with this: string removePunctuation$($string word$)$ and string wordToLowerCase$($string word$).$ See the comment headers for these functions to determine how to use them.

ii$)$ For each word read in$,$ the function should check if it is in the words vector

iii$)$ If it is$,$ the element at the same index in the wordCount vector should be incremented by $1$

iv$)$ If the word is not in the words vector, it should be pushed onto the words vector and $1$ should be pushed on to the wordCount vector

$($d$)$ Hint: Make sure you user your containsWordremovePunctuation and wordToLowerCase

$($e$)$ Test $2$ will test the function. You can submit after writing the function to see if it works correctly. You do not need to finish main first.

$(3)$ Write the function writeOutputFile

$($a$)$ Place a prototype above main$()$ under the comment

$//$ Add the remaining three function prototypes here

void writeOutputFile$($vector words, vector wordCount, ofstream& file$)$;

$($b$)$ Write a definition for this function below main$()$ under the appropriate comment

$($c$)$ This function should write word in the words vector along with the corresponding value from the wordCount vector separated by a space to the already opened file. Each word with it's count should be written on a separate line. The last line of the file should be the total number of words in the words vector.

Example output to the file:

the $102$

three $3$

little $43$

pigs $5...$

happily $1$

ever $1$

Total words: $260$

$($d$)$ This function will be tested with step $4$

$(4)$ Finish writing the function main$()(10$ pt$)$

The main$()$ function has several lines of code for you todo. Write the code to complete each TODO in main$()$
