頭文件graphics.h包含getx()函數,該函數返回當前位置的X坐標。句法:
int getx();
例:
說明:最初,當前位置的X坐標為0。使用moveto()函數移動坐標時,X坐標更改為80。
下麵是getx()函數的實現:
// C Implementation for getx() 
#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, "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;
