Problems with getline() function?

Question

I have a problem with the getline function in the code below. In the "get" info section I want to be able to store a whole sentence, but I can't make it work.

When I open up my program it just skips the input for the info.

p.s: I'm new to C++

Here is the section of the code where i have the problem (Enter the information):

void add() {
    string name;
    string faction;
    string classe;
    string race;
    string info;

    ofstream wowdatabase("wowdatabase.txt", ios::app);
    cout << "Add a race or class" << endl;
    cout << "---------------------------------------------------------" << endl;
    cout << "" << endl;
    cout << "Enter the name of the race or class (only small letters!):" << endl;
    cin >> name;

    cout << "Enter Race (Type -, if writen in name section):" << endl;
    cin >> race;

    cout << "Enter Class (Type -, if writen in name section):" << endl;
    cin >> classe;

    cout << "Enter faction (Alliance/Horde):" << endl;
    cin >> faction;

    cout << "Enter the information:" << endl;
    getline(cin, info);

    wowdatabase << name << ' ' << faction << ' ' << classe << ' ' << race << ' ' << info << endl;
    wowdatabase.close();
    system("CLS");
    main();
}

Now it works fine =) but, when i want to output the info again it only shows the first word in the sentence?

Just a little thing here : `cout << "" << endl;`you don't need the `""`, just `cout << endl;` will suffice. — olevegard, Jan 06 '14 at 14:46

Before this statement

getline(cin, info);

make the following call

cin.ignore( numeric_limits<streamsize>::max(), '\n' );

To use this call you must include header <limits>.

The problem is that after executing statement

cin >> faction;

the new line character that corresponds to enetered key ENTER is in the input buffer and the next getline call reads this character.

After you read fraction an empty line character will be left over. The consequent call to getline will read it. To avoid that add a call to cin.ignore before the getline call.
