C语言中的gety()函数

头文件graphics.h包含gety()函数，该函数返回当前位置的Y坐标。
句法 ：

int gety();

例子 ：

说明：最初，当前位置的Y坐标为0。使用moveto()函数移动坐标时，Y坐标更改为50。

下面是gety()函数：

// C Implementation for gety()
#include 
#include 
  
// 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, "Current position of y = %d", 
                                     gety());
  
    // outtext function displays text at
    // current position.
    outtext(arr);
  
    // moveto function
    moveto(80, 50);
    sprintf(arr, "Current position of y = %d",
                                     gety());
  
    // outtext function displays text at
    // current position.
    outtext(arr);
  
    getch();
  
    // closegraph function closes the
    // graphics mode and deallocates
    // all memory allocated by
    // graphics system .
    closegraph();
  
    return 0;
}
