Write a C-code which generates a font interactively.This means after every n mouse clicks, a Bezier curve is generated and then the terminal point of the last drawn Bezier curve is taken as the initial point of the next Bezier curve and so on, until the user right clicks the mouse. In this case the curve of desired degree is drawn and the multi piece font boundary is generated. If the font generation required further drawing, the program allows starting again on the same window with previously drawn multi-piece curve.But this time the new curve will start with the fresh selected new point.
