I need some help with the following:

I need to write a function called PrintLine that can be called three ways...

PrintLine("Some Text", 15);

PrintLine("Some Text");

PrintLine();

Can you help me with writing such a function?

Thanks.

void PrintLine(char *text=NULL, int value=0)    // Value is the line-lenght maybe?
{
     if (text==NULL)
          // print some default text
     if (value==0)
          // take some action for this

      // print your line here
}
