Question

Program Description: (C++).

Write a word search program that searches an input data file for a word specified by the user. The program should display the number of times the word appears in the input data file. In addition, the program should count and display the number of characters in the input data file that are not vowels. Your program must do this by providing the following functions :

void processFile(ifstream &inFile, string &word, int &wordCount, int &nonVowelCount) ;

void displayResult(string word, int wordCount, int nonVowelCount) ;

Both functions should be called from main(). No non-constant global variables should be used.

Test your program using the file provided “paragraph.dat”.

"You'll generally read and write longer paragraphs in academic papers. However, too many long
paragraphs can provide readers with too much information to manage at one time. Readers
need planned pauses or breaks when reading long complex papers in order to understand your presented
ideas. Remember this writing mantra: "Give your readers a break!" or
"Good paragraphs give one pause"."

ANSWER:

#include<iostream>

#include<fstream>

using namespace std;

int getNonVowelCount(string &word)

{

int count=0;

for(int i=0; i<word.size(); i++)

{

switch(word.at(i))

{

case 'a':break;

case 'e':break;

case 'i':break;

case 'o':break;

case 'u':break;

case 'A':break;

case 'E':break;

case 'I':break;

case 'O':break;

case 'U':break;

default: count++;

}

}

return count;

}

string removePunctuations(string word)

{

string newString=word;

while(true)

{

if(newString.size()==0)

break;

switch(newString.at(newString.size()-1))

{

//remove last charactre if its a punctuation mark

case '!':newString=newString.substr(0, newString.size()-1);break;

case '.':newString=newString.substr(0, newString.size()-1);break;

case '?':newString=newString.substr(0, newString.size()-1);break;

case '\'':newString=newString.substr(0, newString.size()-1);break;

case '\"':newString=newString.substr(0, newString.size()-1);break;

default: return newString;//else return the trsing

}

}

return newString;

}

void processFile(ifstream &inFile, string &word, int &wordCount, int &nonVowelCount)

{

string curWord;

int nonVowelC=0;

int wCount=0;

while(!inFile.eof())

{

inFile>>curWord;

string noPunctuation=removePunctuations(curWord);

if(noPunctuation.compare(word)==0)

wCount++;

nonVowelC+=getNonVowelCount(curWord);

}

nonVowelCount=nonVowelC;

wordCount=wCount;

}

void displayResult(string word, int wordCount, int nonVowelCount)

{

cout<<"\n\nWord: "<<word<<endl;

cout<<"Word Count: "<<wordCount<<endl;

cout<<"Non Vowel Count: "<<nonVowelCount<<endl;

}

int main()

{

ifstream input;

input.open("paragraph.dat");

string word="";

int wordCount=0;

int nonVowelCount=0;

cout<<"Enter a word to search in the file."<<endl;

cin>>word;

processFile(input, word, wordCount, nonVowelCount);
