📜  C语言中的getx()函数

📅  最后修改于: 2021-05-25 19:40:58             🧑  作者: Mango

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

int getx();

例子 :

说明:最初,当前位置的X坐标为0。使用moveto()函数移动坐标时,X坐标更改为80。

下面是getx()函数:

// C Implementation for getx()
#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 x = %d", 
                                     getx());
  
    // outtext function displays text at
    // current position.
    outtext(arr);
  
    // moveto function
    moveto(80, 50);
    sprintf(arr, "Current position of x = %d", 
                                     getx());
  
    // 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;
}
