    cout << "Enter file name: ";
    string fname;
    cin >> fname;
    ifstream fin;

    clock_t start = clock();

    // Open it and  check it here
    string word2;
    vector<string> str_wrd2;
    while (fin >> word2)
    {
        str_wrd2.push_back(word2);
        
    }
    
    fin >> word2;
    for (int i = 0; i < word2.length(); i++)
    {
        if (islower(word2[i]))
        {
            isupper(word2[i]);
        }
        if (!isalpha(word2[i]))
        {
            fin.unget();
        }
        
    }
     cout << "This word is not contained in the Dictionary: ";
    for (int i = 0; i < word2.length(); i++)
    {
        if (str_wrd2[i] != store[i])
        {
            
            cout << str_wrd2[i];
        }
    }
    
    
    // Don't change this
    clock_t end = clock();
    cout << "Time to check is " << (end - start) / CLOCKS_PER_SEC
        << " seconds. " << endl;
    
    return 0;
}

This is what i have so far and entering moby.txt this prints out

Enter file name: moby.txt
This word is not contained in the Dictionary: MOBYDICK;ORTHEWHALEbyHermanTime to check is 0 seconds. 

im pretty sure it has something to do with the while loops but dont know what it is. any help would be much appreciated thank you =]

oh and this is the pseudocode:
Open words.txt dictionary
Read the file, storing each word in a vector of string
Ask the user for the file to check and open the file
For each word in the file
Strip out any non-alpha characters and convert word to lowercase
If the word is not contained in the dictionary, print it
Print the number of "misspelled" words printed
