函数名: moveto 
 功  能: 将CP移到(x, y) 
 用  法: #include <graphics.h> 
         void far moveto(int x, int y); 
 程序例: 
#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());
