#include<bits/stdc++.h>

using namespace std;

int main(){
//declaring fstream object file
fstream file;

//initializing the string variables
string word,filename,search;
int frequency = 0,count = 0;

//input text file
filename = "input.txt";

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

//asking the user to enter the word to be searched in the text file
cout<<"Enter the word to be searched in the text file:"<<endl;
cin>>search;

//loop to search the word
while(file>>word){
//keeping a count of the words
count += 1;
if(word == search){
//if the word is found

//frequency is increased
frequency += 1;
//the number of words after which the searched word was found is displayed
cout<<"The word '"<<search<<"' found at word index: "<<count<<endl;
}
}

//the frequency of the word is printed in the console
cout<<"The frequency of the word '"<<search<<"' in the text file is: "<<frequency<<endl;

return 0;
}
