What representation are you using in Page to hold a page?

For this example I would have a page being an array of characters where each is initialised to a space. Then drawing is simply a matter of setting the appropriate character. Once all the drawing has been done you then emit the page to stdout.

Can you look at the code and give me an example ?

Your page, as far as I can see only has a width and a height.

No storage for the representation of the page itself.

class Page
char *pagedata;

            pagedata=new char[width*height];

            delete pagedata;

       plot_character(int x,int y,char c)

       void print_page()
             int y=0;
             char *p=pagedata;
             while (y < height)

Still can't figure it out.

What do i put in the main() function that will let me print points and lines anywhere i want in the page ?

How about have the main program reading in from stdin a load of text rows, where each row is a sequence of pairs of coordianets describing a path.

Then read the textual representation and create

(a) a page

(b) a series of point collections where each list of points is a path

when you read EOF then render the page into the sequence of characters and print out on stdout.
