一个简单的玫瑰花程序（二）这个玫瑰花的程序我在3月28日就发过了，可是问题不少，在这个语句（arc(x+64,y-57,300,490,17);）中出现了颜色外泻，请注重，终止角是490度，而不是460度，不过还没有写完，大家可以凭自己的爱好添家或删除其中的语句，绘出更漂亮的图形。谢谢合作！作者：张某地址：云南农叶大学修改后的程序如下：#include <stdio.h>
#include <dos.h>
#include <graphics.h>
#include <math.h>#define FNX(x) (int)(xo+(x)*1.0)
#define FNY(y) (int)(getmaxy()-(yo+(y)*1.0))
#define FNX2(phi) cos(phi)*ac-sin(phi)*bs
#define FNY2(phi) cos(phi)*as+sin(phi)*bc/*画旋转的椭圆*/
void elli(int xo,int yo,int a,int b,double theta)
{
int i;
double da,c,s,ac,as,bc,bs,xf,yf,phi,x,y;
theta=theta*0.01745;
