C program to create Indian National Flag using Graphics

In this article, we will discuss how to draw the Indian National Flag using Graphics.

Approach:

• Draw a rectangle using the function rectangle().
• Equally, divide the above rectangle into three parts by creating the line using the function line().
• Draw double lines on each other i.e., draw 4 lines and among them, 2 lines will act as a divider between Red (Light red as there is no direct saffron color present in the graphics library) & White, and the other 2 lines will divide White and Green color.
• The Ashoka Chakra will be made using the function circle().
• To finish, all the spaces will be filled using the functions setfillstyle() and floodfill().

Below is the implementation of the above approach:

C

// C program for the above approach

#include <conio.h>
#include <graphics.h>
#include <stdio.h>

// Driver Code
void main()
{
    // Initialize of gdriver with
    // DETECT macros
    initgraph(&gd, &gm, "C:\\turboc3\\bgi");

    // Creating the base rectangle
    line(250, 100, 250, 600);
    line(250, 100, 250, 600);

    // Fill the White Color
    setfillstyle(SOLID_FILL, WHITE);

    // Create and fill the top strip
    rectangle(225, 600, 275, 610);
    rectangle(200, 610, 300, 620);

    floodfill(227, 608, 15);
    floodfill(202, 618, 15);

    // Fill the Light Red Color
    setfillstyle(SOLID_FILL, LIGHTRED);

    // Create and fill the ashoka
    // chakra with Blue
    rectangle(250, 100, 650, 280);
    line(250, 160, 650, 160);
    floodfill(252, 158, 15);

    // Fill the Blue Color
    setfillstyle(SOLID_FILL, BLUE);

    // Create and fill the left
    // part of the middle strip

    // Create a Circle
    circle(450, 190, 30);
    floodfill(452, 188, 15);

    // Fill the White Color
    setfillstyle(SOLID_FILL, WHITE);

    // Create and fill the right
    // part of the middle strip
    line(250, 160, 480, 160);
    line(250, 220, 480, 220);
    floodfill(252, 162, 15);

    // Fill the White Color
    setfillstyle(SOLID_FILL, WHITE);

    // Create and fill the bottom
    // strip
    line(480, 160, 650, 160);
    line(480, 220, 650, 220);
    floodfill(482, 162, 15);

    // Fill the Green Color
    setfillstyle(SOLID_FILL, GREEN);

    line(250, 220, 650, 220);
    floodfill(252, 278, 15);

    // Close the initialized gdriver
    closegraph();
}

Output:
