XY工作臺四個象限的直線插補程序

1、求助四個象限的直線插補程序2011-5-16 21:55最佳答案#i nclude <stdio.h>#in elude <graphics.h> /* <- in eluded for putpixel() */#include <stdlib.h> /* <- included for abs() */void cb_li ne(i nt x1, i nt y1, i nt x2, i nt y2)int dx, dy, n, k, i, f;int x, y;dx = abs(x2-x1);dy = abs(y2-y1);n = dx +

2、dy;if (x2 >= x1) k = y2 >= y1 ? 1: 4;x = x1;y = y1; else k = y2 >= y1 ? 2: 3;x = x2;y = y2;putpixel(x, y, 1);for (i = 0, f = 0; i < n; i+)if (f >= 0)switch (k) case 1:putpixel(x+, y, 1);f -= dy;break;case 2:putpixel(x, y+, 1); f -= dx;break;case 3:putpixel(x-, y, 1); f -= dy;break;cas

3、e 4:putpixel(x, y-, 1);f -= dx;break;elseswitch (k) case 1:putpixel(x, y+, 1); f += dx;break;case 2:putpixel(x-, y, 1);f += dy;break;case 3:putpixel(x, y-, 1);f += dx;break;case 4:putpixel(x+, y, 1);f += dy;break;int mai n()cb_li ne(0,0,15,20); /* <- you forgot ; here */return 0; /* better return

4、 somethi ng */語言直線插補程序，高手請進采納后追加20分2010-11-8 22:39提問者：1004459133夜曲|懸賞分：5|瀏覽次數(shù)：725次我用c語言寫了一個直線插補程序，用來模擬數(shù)控機床的直線插補運動，但是在c-free軟件中總是無法運行，提示頭文件錯誤，那位高手幫忙解決一下，(在我的基礎(chǔ)上修改)請盡量詳細說明，指導(dǎo)我把這個問題解決就算被采納。具體程序如下：#i nclude <stdio.h>#in clude <graphics.h>#i nclude "con io.h"void mai n()float x1,y1,

5、x2,y2, n1, n2,xe,ye,f, n;prin tf("n請輸入直線的第一個點n");scan f("%f,%f', &x1, &y1);prin tf("n請輸入直線的第二個點n");scan f("%f,%f',x2,y2);/*判斷需要走的步數(shù)*/n1= (y2-y1)>=0?(y2-y1)*100:(y1-y2)*100;n 2=(x2-x1)>=0?(x2-x1)*100:(y2-y1)*100;n=n1+n2;/*第一象限內(nèi)的直線*/ if(x2>=x1) &a

6、mp;&(y2>=y1)int gdriver=DETECT,gmode; int x,y;in itgraph(&gdriver, &gmode,""); cleardevice();xe=x2-x1;ye=y2-y1; moveto(x1,y1);for(f=0; n>O;n-)if(f>=0)li nerel(O.O1,O); f-=ye;elseli nerel(O,O.O1); f+=xe;/*第二象限內(nèi)的直線*/ if(x2>=x1) &&(y2>=y1)int gdriver=DETECT,

7、gmode; int x,y;in itgraph(&gdriver, &gmode,""); cleardevice();xe=x2-x1;ye=y2-y1; moveto(x1,y1);for(f=0; n>O;n-)if(f>=0)li nerel(O.O1,O); f-=ye;elseli nerel(O,O.O1);f+=xe;/*第三象限內(nèi)的直線*/ if(x2<x1)&&(y2>y1)int gdriver=DETECT,gmode; int x,y;in itgraph(&gdriver, &a

8、mp;gmode,""); cleardevice();xe=x2-x1;ye=y2-y1; moveto(x1,y1);for(f=0; n>O;n-)if(f>=0)li nerel(O.O1,O);f-=ye;elseli nerel(O,-O.O1); f+=xe;/*第四象限內(nèi)的直線*/ if(x2<x1)&&(y2<y1)int gdriver=DETECT,gmode; int x,y;in itgraph(&gdriver, &gmode,""); cleardevice();xe=x2-x1;ye=y2
