getx() function in C
  • Difficulty Level : Medium
  • Last Updated : 25 Jan, 2018

The header file graphics.h contains getx() function which returns the X coordinate of the current position.
Syntax :

int getx();

Example :


Explanation : Initially, the X coordinate of the current position is 0. On moving the coordinates using moveto() function, the X coordinate changes to 80.

Below is the implementation of getx() function:




// 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;
}
