Question

In c++ please. Write a program that opens a specified text tile then displays a list of all the unique words found in the file. Hint: Store each word as an element of a set.

Answer 1

C++ code :

#include <bits/stdc++.h>
using namespace std;

// driver code
int main()
{
   // filestream variable file
   fstream file;
   string word, t, q, filename;
   set<string> s;
   //set<string>::iterator it;

   // filename of the file
   filename = "paragraph.txt";

   // opening file
   file.open(filename.c_str());

   // extracting words from the file
   while (file >> word)
   {
       // displaying content
       cout << word << endl;
       s.insert(word);               //insert words into set.
   }

   for(auto i=s.begin();i!=s.end();i++)
    {
      cout<<*i<<endl;                 //print the words.
    }

   return 0;
}

Output:
