How to create Pixel in C , C++

 

//c implementation for pupixel()

#include<stdio.h>

#include<graphics.h>

#include<conio.h>

//drive code

void 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, color;

// initgraph initializes the

// graphics system by loading a

// graphics drive from disk

initgraph(&gd, &gm, " ");

//putpixel function

putpixel(85, 35, GREEN);

putpixel(30, 40, RED);

putpixel(115, 50, YELLOW);

putpixel(135, 50, CYAN);

putpixel(45, 60, BLUE);

putpixel(20, 100, WHITE);

putpixel(200, 100, LIGHTBLUE);

putpixel(150, 100, LIGHTGREEN);

putpixel(200, 50, YELLOW);

putpixel(120, 70, RED);

getch();

//closegraph function closes the

//graphics mode and deallocates

//all memory allocated by

//graphics system  .

closegraph();
