    help on this very small practice program

    /*Ok first of all I just want to tell you that by this you're not doing my homework, because I am learning on my own right now.....This is just from a book that I am reading....and I decided to do something extra */
    //Listing 10.1 Overloading class member functions

    #include <iostream>

    // Rectangle class declaration
    class Rectangle
    {
    public:
    // constructors
    Rectangle(int width, int height);
    ~Rectangle(){}

    // overloaded class function DrawShape
    void DrawShape() const;
    void DrawShape(int aWidth, int aHeight) const;

    private:
    int itsWidth;
    int itsHeight;
    };

    //Constructor implementation
    Rectangle::Rectangle(int width, int height)
    {
    itsWidth = width;
    itsHeight = height;
    }


    // Overloaded DrawShape - takes no values
    // Draws based on current class member values
    void Rectangle:rawShape() const
    {
    DrawShape( itsWidth, itsHeight);
    }


    // overloaded DrawShape - takes two values
    // draws shape based on the parameters
    void Rectangle:rawShape(int width, int height) const
    {
    for (int i = 0; i<height; i++)
    {
    for (int j = 0; j< width; j++)
    {
    std::cout << "*";
    }
    std::cout << "\n";
    }
    }

    // Driver program to demonstrate overloaded functions
    int main()
    {
    // initialize a rectangle to 30,5
    Rectangle theRect(30,5);
    std::cout << "DrawShape(): \n";
    theRect.DrawShape();
    std::cout << "\nDrawShape(40,2): \n";
    theRect.DrawShape(40,2);
    return 0;
    }

    /* I want to creat a member method that takes in one pararemeter either width or height.... so then I can overload drawshape, and then getting the other missing argument by means of using enum, please help...........*/

    My recommendation is to leave that book completely. I was doing the same thing that you are doing only to find out that I had missed a lot of key information that it missed. Therefore, I had to start all over using a different book. Goto this site:

    cin >> width;
    height = (rand() % 3) + 1;//use enum here instead if you wish
    DrawShape(width, height);
    case 2:
    //similar for width

    }
    cout << "to stop enter zero' << endl;}
