自己写的一个产生分形树叶的c++程序，

fra.cpp是产生分形的主程序，bmp.cpp是把产生的图形写到bmp文件里去，IFS则是产生分形树叶的迭代算法。生成bmp图片是自己写的程序，没有调用系统函数，所以可在任何系统下运行。 程序运行产生一个画了分形树叶的bmp文件。-wrote it myself have a fractal leaves c procedures fra.cpp generated fractal is the main program. bmp.cpp is the Graphics wrote bmp paper somewhere, IFS is generated fractal algorithm leaves. Bmp image is generated its own written procedures, no calling system function, there is no system in operation. Procedures produce a painting of fractal leaves bmp document.
