Unused Character

[Extreme112]

Upon compilation I get a warning saying that "variable ‘z’ set but not used". How do I fix this?

  void num_chars(vector<string> words)
{
    ifstream fin(words[1]);
    char z = fin.get();
    int char_count = 0;
    while (!fin.eof())
    {
        ++char_count;
        z = fin.get();
    }
    cout << words[1] << " contains " << char_count << " characters. \n\n";
}

Why are you initializing z as fin.get() and then assigning it to fin.get() again, inside the while loop?

Also, is there any way we can get the rest of your program? It makes troubleshooting monumentally easier.
