tc 下的代码转化为 easyx 下的代码!怎么才能实现呢
//螺旋六边形#include <graphics.h>
#include <math.h>
void polygonc();
void main()
{
int i,r,n,x=320,y=240;
int gdriver=9,gmode=2;
float theta,alfa;
n=30;
theta=6.0;
initgraph(&gdriver,&gmode,"c:\\tc");
cleardevice();
setbkcolor(MAGENTA);
setcolor(WHITE);
r=160;
alfa=60.0;
for(i=0;i<n;i++)
{
polygonc(x,y,r,6,alfa);
r=(int)(0.866*r/cos((30.0-theta)*0.0174533));
alfa=alfa+theta;
}
getch();
closegraph();
}
void polygonc(x0,y0,r,n,af)
int x0,y0,n,r;
float af;
{
int x,y,xs,ys,i;
float dtheta,theta;
if(n<3)
return;
dtheta=6.28318/n;
theta=af*0.0174533;
xs=x0+r*cos(theta);
ys=y0+r*sin(theta);
moveto(xs,ys);
for(i=1;i<n;i++)
{
theta=theta+dtheta;
x=x0+r*cos(theta);
y=y0+r*sin(theta);
lineto(x,y);
}
lineto(xs,ys);
}
