Question

Please write a C++ code that inputs a CSV file, asks the user if they'd like to remove certain words from the file, and removes the words from the file.

Please note that the CSV file has two columns, the first with the words, and the second with a count of how many times each word appears.

Answer 1

Remove certain words from the file, and removes the words from the file.

#include <iostream>

#include <cstring>

using namespace std;

int main(){

   char string[100], pattern[100];

   char *ptr;

   int length;

   cout << "Enter a string\n";

   cin.getline(string, 100);

    cout << "Enter string to remove\n";

   cin.getline(pattern, 100);

   length = strlen(pattern);

   ptr = strstr(string, pattern);

   strcpy(ptr, ptr+length);

   cout << "Final String\n" << string;

   return(0);

}

Second with a count of how many times each word appears.

#include <bits/stdc++.h>

using namespace std;

int countOccurences(char *str,

                    string word)

{

    char *p;

vector<string> a;

p = strtok(str, " ");

    while (p != NULL)

    {

        a.push_back(p);

        p = strtok(NULL, " ");

    }

int c = 0;

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

if (word == a[i])

            c++;

    return c;

}

int main()

{

    char str[] = "Count the Number of words you want to search count the words ";

    string word = "words";

    cout << countOccurences(str, word);

    return 0;

}

// Hence in Sample Input words are occuring two times

so , OUTPUT = 2.
