To Plot Point Pixel on Screen

To Plot Point Pixel on Screen in cpp using computer graphics library.In this code initialize graphics Library  make background to white we find center position in X axis,& Y axis.Now we put pixel in center positions.

Code

#include<graphics.h>
#include<iostream.h>
#include<conio.h>
#include<stdlib.h>
void get_driver(){
   int gDriver=DETECT,gMode;  // define variables
   initgraph(&gDriver,&gMode,"c:\\tc\\bgi");  // initialize graphics Library
   setbkcolor(15);  // make background to white
}

void main(){
   get_driver();// To make function of define drivers
   int dx,dy,x,y; //define variables
   x = abs(getmaxx()/2);  // To get center on x axis
   y = abs(getmaxy()/2); // To get center on y axis
   putpixel(x,y,4);  //for put pix
   getch(); // getch used to hold program execution
}
