头文件graphics.h包含moveto()函数,该函数将当前位置更改为(x,y)
用法:
void moveto(int x, int y);
例子:
Input:x = 70, y = 40 Output: Input:x = 50, y = 80 Output:
下面是moveto()函数的实现:
// C Implementation for moveto()
#include <graphics.h>
#include <stdio.h>
// driver code
int main()
{
// gm is Graphics mode which is
// a computer display mode that
// generates image using pixels.
// DETECT is a macro defined in
// "graphics.h" header file
int gd = DETECT, gm;
char arr[100];
// initgraph initializes the
// graphics system by loading a
// graphics driver from disk
initgraph(&gd, &gm, "");
// sprintf stands for “String print”.
// Instead of printing on console, it
// store output on char buffer which
// are specified in sprintf
sprintf(arr, "X = %d, Y = %d", getx(),
gety());
// outtext function displays text at
// current position.
outtext(arr);
// moveto function
moveto(70, 40);
// The function getx returns the X
// coordinate of the current position.
// The function gety returns the y
// coordinate of current position.
sprintf(arr, "X = %d, Y = %d", getx(),
gety());
outtext(arr);
getch();
// closegraph function closes the
// graphics mode and deallocates
// all memory allocated by
// graphics system .
closegraph();
return 0;
}
