Thread: File I/O Reading from file

Hi, what am I doing wrong I'm reading from a file with words and trying to get the output properly. I know it's reading, and counting the amount of words in it. But when I try to output I get a bunch of gibberish. Any help would be appreciated.

In main I call the load function as follows:

Code:

Myobject newobject;
string filename;cout << "enter filename ";
cin >> filename; newobject.loadthisfile(filename);

Then the function is as follows:

Code:

SIZE=4


void Myobject::loadthisfile(const string & filename)
{
    ifstream input(filename.c_str());
    string newword;
    if (input.fail())
    {
    cout << "couldn't not open file " << filename << endl;
    exit(1);
    }
    
    while (getline(input,newword))              // read one line
    {
    newword = newword.substr(0,SIZE);     // 
    if (isalpha(newword[0]))                //
    {


       if (wordscount >= wordlist.size())  // double  if needed
            {
                wordlist.resize(wordlist.size() * 2);
            }
            wordlist[wordscount] = new Myobject(newword);
            cout<<wordlist[wordscount]<<endl;                 //// produces gibberish ERROR here
            wordscount++;
            cout<<wordscount<<endl;                ///echoes proper number of words from textfile
        
    }
    }
}

What is 'wordlist' ? It seems you're storing 'MyObject' instances into 'wordlist' and then trying to output that ?

Have you overloaded the output operators for class 'MyObject' at least ?

wordslist is of type vector<Myobject*>mywordslist

In that case you might want to overload the output operators for your 'MyObject' class.

Another easier way would be instead of having a vector of 'MyObject', assuming you only want to store the strings, why not just have a vector of strings ?

Code:

std :: vector<std :: string> mywordlist;

Then instead of creating new 'Myobject' instances based on the current string - just push the string into the vector

Code:

mywordlist.push_back(newword);
