String Comparision

How are the word files stored in a text file.

I am trying to take a word as input from and comparing that word with the words present in my local path.

how to compare the input word to the words in the file.

#include <iostream>
#include <fstream>
using namespace std;

string str;
fstream file;
string word, t, q, filename;

void read()
{
    cout << "Enter the word to search in the dictionary:";
    cin >> str;
    cout << "Your Entered word is :" << str;
    cout << "\nsearching in the librabry(Dictionary).";
    return;
}

void search()
{
    //string str;
    filename = "da1.txt";

    file.open(filename.c_str());
    if (str == word)
    {
        cout << "Found" << word << endl;
    }
    else
    {
        cout << "\nEntered word does not exist in the library." << endl;
    }
    return;
}

int main()
{
    search();
}

I am pretty sure that my word is not being compared to the words in the text.

Your are not calling your method read(), so your var word is null.
Secondly, it seems you want to know if str contain word, instead of a simple equal. Check out this link.
As noted @Paul Sanders, you are not reading data from your file

Your issue is here:

void read()
{
  cout<<"Enter the word to search in the dictionary:";
  cin>>str;
  cout<<"Your Entered word is :"<<str;
  cout<<"\nsearching in the librabry(Dictionary).";
  return;
}

and is caused because:

  1. read() method is never called,
  2. you ask for a word to search but assign that input to str variable
  3. in search method you do if(str==word) so you compare 2 non initialized objects
  4. you should do something like std::string str{};
