错误错误错误！

问题描述

我正在使用turbo c complier获取给定代码： -

i am using turbo c complier for the given code :-

#include<iostream.h>
#include<conio.h>
#include<graphics.h>
class hexa
{
    private:
int x,y,pts[12][12],s;
float h,r;
   public:

void set(){
cout<<"enter the cordinates";
cin>>x>>y;
cout<<"enter the length of hexagonal";
cin>>s;
}
void disp(){
cout<<x<<y;
cout<<s;
}


void Draw()
    {
h = 0.5* s;
r = 0.866*s;



                pts[0][0] =x; pts[0][1] =y;
                pts[1][0] =x+h; pts[1][1] = y+r;
                pts[2][0] =x; pts[2][1] = y+r;
                pts[3][0] =x-h; pts[3][1] =y+r;
                pts[4][0] =x;  pts[4][1] =y-r;
                pts[5][0] =x-h;   pts[5][1] =y-r;
                pts[6][0] =x+h;  pts[6][1] =y-r;


  drawpoly(7,pts[0][0],pts[0][1],pts[1][0],pts[1][1],pts[2][0],pts[2][1],pts[3][0],pts[3][1],pts[4][0],pts[4][1],pts[5][0],pts[5][1],pts[6][0],pts[6][1],pts[0][0],pts[0][1]);





}

};

main()
{
hexa c;

   int gd=DETECT,gm;
   initgraph(&gd, &gm, "C:\\TurboC3\\BGI");

c.set();
c.disp();
c.Draw();


   getch();
   closegraph();
   return 0;


}

它会出现以下错误： -

1）无法将int转换为const int远*

2）类型不匹配参数_polypoints调用drawpoly（int，const int far）

3）额外参数in调用drawpoly（int，const int far）





无法恢复错误plz帮助我..我会谢谢你。

and it gives the following errors :-
1)cannot convert int to const int far*
2)type mismatch parameter _polypoints to call a drawpoly(int,const int far)
3)extra parameter in call to drawpoly(int,const int far)


am not able to recover errors plz help me .. i''ll be thankfull to uh.

推荐答案

drawpoly(7,pts[0][0],pts[0][1],pts[1][0],pts[1][1],pts[2][0],pts[2][1],pts[3][0],pts[3][1],pts[4][0],pts[4][1],pts[5][0],pts[5][1],pts[6][0],pts[6][1],pts[0][0],pts[0][1]);

我认为你应该这样做;

I think you should do;

drawpoly(7, pts);

因为函数需要一个项目计数和指向它们的指针，而不是每个项目单独。



希望这会有所帮助，

as the function expects a count of items and a pointer to them, not each item individually.

Hope this helps,
