How to make a bar graph?

whatisjeff (25)
I wrote a program that allows the user to generate their own poll and tally up the results of the input. At the end, I want the results to be displayed as a horizontal bar graph. Here is what I have so far:

    getline(cin,a3, '\n');

    //Tallying the poll

    cout <<"Here is your poll. Start the tally by selecting an answer. \n";

    while (a!=0)
    {
        cout << poll << '\n' << "1. "<< a1 << '\n' << "2. " << a2 << '\n' << "3. " << a3 << '\n' << "(Enter 0 to stop the poll.)" << '\n';
        cin >> a;

        if (a==1)
        {
            x++;
            cout <<"Thank you for your time. Next person please. \n";
            continue;
        }

        else if (a==2)

        {
            z++;
            cout <<"Thank you for your time. Next person please. \n";
            continue;
        }

        /*Results of the poll. I tried to take a crack at it but I don't know   how to repeat the asterisk so that they go horizontally.*/

        else if (a==0)
        {
            cout <<"Here are the results of your poll: \n";
            cout <<"1 * = 1 vote. \n";

            cout << a1 << '\n';
            for (b=0;b!=x;b++)
            {
                cout << "* \n";
            }

            cout << a2 << '\n';
            for (c=0;c!=y;c++)
            {
                cout << "* \n";
            }

            cout << a3 << '\n';

        }

        else

            cout <<"I'm sorry, that was not a viable answer. Please try again. \n";
            continue;
        }

    }

Omit the \n after each *.
Does this work better for lines 73-89?
