moveto

moveto是計算機術語。

基本介紹

• 中文名：moveto
• 功 能：將CP移到(x, y)
• 用 法：void far moveto(int x, int y)
• 函式名：moveto

基本信息

CDC::MoveTo（int x,int y)

Cpoint MoveTo(int x,int y)

Cpoint MoveTo(POINT point)

x：新位置的橫坐標

y：新位置的縱坐標

point：標識的一個新的位置，以POINT 結構或CPoint 類對象的形式表示。

程式例

#include <graphics.h>

#include <stdlib.h>

#include <stdio.h>

#include <conio.h>

int main(void)

{

/* request auto detection */

int gdriver = DETECT, gmode, errorcode;

char msg[80];

/* initialize graphics and local variables */

initgraph(&gdriver, &gmode, "");

/* read result of initialization */

errorcode = graphresult();

if (errorcode != grOk) /* an error occurred */

{

printf("Graphics error: %s\n", grapherrormsg(errorcode));

printf("Press any key to halt:");

getch();

exit(1); /* terminate with an error code */

}

/* move the C.P. to location (20, 30) */

moveto(20, 30);

/* plot a pixel at the C.P. */

putpixel(getx(), gety(), getmaxcolor());

/* create and output a message at (20, 30) */

sprintf(msg, " (%d, %d)", getx(), gety());

outtextxy(20, 30, msg);

/* move to (100, 100) */

moveto(100, 100);

/* plot a pixel at the C.P. */

putpixel(getx(), gety(), getmaxcolor());

/* create and output a message at C.P. */

sprintf(msg, " (%d, %d)", getx(), gety());

outtext(msg);

/* clean up */

getch();

closegraph();

return 0;
