Question

please write it in c++ programming language

Write a program that reads files and prepares an statistical summary for each file processed with the following information: • total number of words in the report; • number of unique words: • number of unique words of more than four letters; Input From the keyboard: 1. The name of the files containing the text to be analyzed From the file: The report to be analyzed; ended by <eof>. Allow the user to continue with another file name or quit. Output 1. For each File being analyzed write the following information to a file. • The name of the file • The statistical summary of the file Data Structures 1. A list of unique words in the report, created as the file is read. If a word is not in the list, put it in the list. If word exists in list, increment a counter showing how many times the word has been used. Word: Sequence of letters ending in a blank, a period, an exclamation point, a question mark, a colon, a comma, a single quote, a double quote, or a semicolon. Numbers do not appear in the words: they may be ignored. Unique word: Words that are spelled the same, ignoring uppercase and lowercase distinctions. Sentence: Words between end of sentence markers or the beginning of the report and the first end of sentence marker. Sample input file attached on blackboard.

this is the rat text file

More what? what more additional information do you want? so i can provide it.

Answer 1

First 3 processed information that you need is given below

C++ Code

#include <iostream>
#include <bits/stdc++.h>
#include <fstream>
#include<string>
int printUniquedWords(char filename[]) ;
using namespace std;
int printUniquedWords(char filename[])
{
    // Open a file stream
    fstream fs(filename);

    // Create a map to store count of all words
    map<string, int> mp;

    // Keep reading words while there are words to read
    string word;
    int uword=0,fourdigits=0;
    while (fs >> word)
    {
        // If this is first occurrence of word
        if (!mp.count(word))
            mp.insert(make_pair(word, 1));
        else
            mp[word]++;
    }

    fs.close();

    // Traverse map and print all words whose count
    //is 1
    for (map<string, int> :: iterator p = mp.begin();
         p != mp.end(); p++)
    {
      
        if (p->second == 1) {
            uword++;
            if((p->first).length()>4){
                fourdigits++;
            }
           // cout <<(p->first).length()<< endl;
        }
    }
    cout<<"\nUniqueWords="<<uword<<"\n";
    cout<<"\nmoreThan4digitUniqueWords="<<fourdigits<<"\n";
}
int main()
{
ifstream fin("rat.txt"); //opening text file
int word=1; //will not count first word so initial value is 1
char ch;

fin.seekg(0,ios::beg); //bring position of file pointer to begining of file

while(fin)
{
fin.get(ch);
if(ch==' '||ch=='\n')
   word++;
}
cout<<"\nTotalWords="<<word<<"\n";
printUniquedWords("rat.txt");
fin.close(); //closing file

return 0;
}

Output

TotalWords:

UniqueWord:

moreThan4digitUniqueWords:
