A small program simulating CAD all coded by C. The program is an assignment from Zhejiang University.
The libraries of the program are all on my another repository "LibraryForC", some of them come from the text book, whose name is "The Art and Science of C Programming language", which Zhejiang University adopted. The main goal of libraries from the text book is to use the API in Windows, providing a easy access to it.
By this simple CAD program, we can draw, move, rotate, zoom in and out the object, including line, rectangle, ellipse. You can also generate the text and move it.
