Question

Ok so im sure im doing something stupid 😀

i have a function:

int wordFunc(string a){
    std::ifstream inp;
    inp.open(a, std::ios::in);
    if (inp.is_open()){
        std::string word;
        unsigned long wordCount = 0;
        while(!inp.eof()){
            inp >> word;
            while(word.length() > 0){
                wordCount++;
            }
            inp.close();
        }
        return wordCount;
    }
}

the string is a user input file.txt – its set to be C:\Dump\user.txt right now

when i call the code with:

int main(){
    string file;
    int words = 0;
    file = "C:\\Dump\\user.txt";

    int a = wordFunc(file, words);
    cout << "Words: " << a << endl;

    return 0;
}

The console just halts – I havnt coded anything in C++ in many a year so im definitely rusty – any help?

EDIT
With the help of some kind sould I ended up going like this

unsigned long wordFunc(const std::string& a){
    std::ifstream inp(a);
    system("cls");
    unsigned long wordCount = 0;
    std::string word;
    while(inp >> word)
    {
        wordCount++;
    }
    return wordCount;
}

For the function – should have posted an update

Your problem is this:

        while(word.length() > 0){
            wordCount++;
        }

This loops forever. You probably mean

        if(word.length() > 0){
            wordCount++;
        }
